## Frequently Asked Questions

### General

**What is pharmacy billing reconciliation?**
Pharmacy billing reconciliation is the process of comparing your dispensing and billing records against purchase invoices and PBM remittance data to verify that every prescription was billed correctly, reimbursed at the right amount, and that your purchasing costs align with your dispensing records.

**What is an NDC swap and why does it matter?**
An NDC swap occurs when the same medication is billed under different National Drug Code (NDC) numbers across your billing and purchasing data  - often due to manufacturer changes or wholesaler substitutions. NDC swaps create phantom shortages and surpluses in your reports and can silently drain revenue if undetected.

**How much revenue do pharmacies lose to billing errors?**
Industry data shows independent pharmacies typically lose 2-5% of prescription revenue to billing discrepancies, PBM underpayments, and undetected errors. For a pharmacy doing $300,000/month in prescription revenue, that's $6,000 to $15,000 per month in lost revenue.

**How does RxDelta work?**
Upload your billing export (CSV) and purchase order data from your pharmacy system. RxDelta automatically matches every NDC code between billing claims and purchases, detects swaps, identifies shortages and overages, and generates a full reconciliation report with insurance-level analytics  - all in under 3 minutes.

**Which pharmacy systems does RxDelta work with?**
RxDelta works with any pharmacy management system that exports CSV data, including PrimeRx, Liberty, Pioneer, Rx30, Computer-Rx, BestRx, and others. Our intelligent header detection automatically recognizes column layouts from different systems.

**How is RxDelta different from doing reconciliation in Excel?**
Manual Excel reconciliation typically takes 4-6 hours and can't detect NDC swaps. RxDelta completes the same work in under 3 minutes with 98%+ accuracy, automatic swap detection, and insurance-level breakdowns by PBM and BIN number that spreadsheets simply can't provide.

### Pricing & Plans

**How does the reconciliation actually work?**
You upload two files  - your billing export (what you charged insurers) and your purchase history (what you bought from your wholesaler). RxDelta automatically detects the column headers, matches every NDC, and calculates the variances. In seconds, you get a detailed report showing shortages, surpluses, swaps, and exactly where to look.

**What file formats can I upload?**
We accept CSV and Excel (.xlsx) files. Our system recognizes column headers automatically using 200+ synonym variations, so there's no manual field mapping on your end.

**Is my pharmacy data safe?**
Absolutely. All data is encrypted with AES-256, both in transit and at rest. We meet enterprise-grade security standards, and we never share your data with anyone.

**Can I cancel anytime?**
Yes  - cancel whenever you want, no fees, no hoops. Your access stays active through the end of your current billing period.

**What's the difference between Data Access and Managed Reporting?**
With Data Access, you upload your own files and run reports yourself  - full control at the best price. With Managed Reporting, we pull the data for you, clean it up, and deliver monthly reports straight to your dashboard. It's completely hands-off, and you get a dedicated account manager.

**What does the Procurement tier include?**
Everything in Managed Reporting, plus the tools to actually buy smarter. You can order medications directly through our platform, track orders in real time, get inventory optimization recommendations, and lean on us for vendor relationship management.

**What do I get with Premium Optimization?**
It's our everything plan. You get real-time overage monitoring with proactive alerts when pricing anomalies pop up, detailed cost analysis to surface savings, strategic consulting on your medication spend, and a dedicated success manager with 24/7 availability.

**I run multiple pharmacies. How does pricing work?**
We offer custom volume pricing for groups with 3+ locations. Reach out to our team and we'll put together a package that includes consolidated reporting, group-level analytics, and pricing that makes sense for your size.

**Is there a free trial?**
We don't offer a free trial right now  - but our Data Access plan starts at just $200/month with no long-term commitment. Try it out, and if it's not the right fit, cancel anytime.

### Our Mission

Independent pharmacies are the backbone of community healthcare. They fill prescriptions, counsel patients, administer vaccinations, and serve as the most accessible healthcare providers in their neighborhoods. But behind the counter, they're fighting a losing battle against billing complexity.

Every month, pharmacies process thousands of prescriptions across dozens of PBM contracts. Each claim has its own NDC code, its own reimbursement rate, its own potential for error. When manufacturers change NDC numbers, when wholesalers substitute products, when PBMs quietly adjust reimbursement rates  - the discrepancies add up. Industry data shows 2-5% of prescription revenue is lost to these undetected errors.

RxDelta was built because pharmacists shouldn't have to choose between patient care and financial survival. Our platform automates the entire reconciliation process  - from file upload to final report  - so pharmacy teams can spend their time where it matters most.

### What We Stand For

- **Accuracy Over Speed**: We process reconciliations in under 3 minutes, but we never sacrifice accuracy for speed. Our 98%+ match rate means pharmacies can trust the results without manual verification.
- **Built for Independent Pharmacies**: Every feature is designed for the specific challenges independent pharmacies face  - not hospital systems, not chain pharmacies.
- **Transparency in Billing**: Pharmacies deserve to know exactly what they're being paid  - and what they're missing.
- **Security First**: All data is encrypted with AES-256 in transit and at rest. We never share, sell, or expose client data.

### Journey

- **2024**: Founded with a goal to eliminate hours of manual billing reconciliation
- **2024**: Onboarded first 10 pharmacies during early access, built intelligent header detection for 200+ column variations
- **2025**: Launched automated NDC swap detection  - mapping NDC families across manufacturers
- **2025**: Crossed 50 pharmacies with $2.4M+ in cumulative revenue recovered
- **2026**: Expanded into procurement optimization and multi-pharmacy group management

## Revenue Leakage Calculator

Free interactive tool to estimate how much revenue your pharmacy loses to billing discrepancies, NDC swaps, and PBM underpayments.

### How Revenue Leakage Works

Revenue leakage in pharmacy billing comes from several sources that compound over time:

1. **NDC Swaps**  - When manufacturers change NDC codes or wholesalers substitute products, the same drug appears under different codes in billing vs purchasing records. These show up as phantom shortages or surpluses.
2. **PBM Underpayments**  - PBMs may reimburse below contracted rates on certain claims, or apply DIR fees retroactively.
3. **Billing-to-Purchase Mismatches**  - Quantity discrepancies between what was billed to insurers and what was purchased from wholesalers.
4. **Manual Process Errors**  - Spreadsheet reconciliation introduces an 8-15% error rate on top of billing discrepancies.

### Industry Data Points

- Average independent pharmacy prescription revenue: $200,000-$500,000/month
- Billing discrepancy rate (industry range): 2-5% of prescription revenue
- Manual reconciliation time: 4-6 hours per pharmacy per month
- Automated reconciliation time: Under 3 minutes
- RxDelta match accuracy: 98%+
- Revenue recovered across 50+ RxDelta pharmacies: $2.4M+

### Example: $300,000/month Pharmacy

- Monthly revenue leakage at 3.5% discrepancy rate: $10,500
- Annual revenue leakage: $126,000
- Recovery with RxDelta (98% accuracy): $10,290/month ($123,480/year)
- RxDelta Data Access plan cost: $200/month ($2,400/year)
- Net annual benefit: $121,080
- ROI: 5,045%

## What Is an NDC Code?

An NDC (National Drug Code) is a unique 10 or 11-digit identifier assigned to every drug product sold in the United States. It follows a 5-4-2 format: 5 digits for the labeler (manufacturer), 4 digits for the product (drug, strength, formulation), and 2 digits for the package (size and type).

### The NDC 5-4-2 Format

- **Labeler Code (5 digits)**: Identifies the manufacturer, repackager, or distributor. Assigned by the FDA. Example: 00071 = Pfizer, 00002 = Eli Lilly.
- **Product Code (4 digits)**: Identifies the specific drug formulation  - active ingredient, strength, and dosage form. Assigned by the labeler. Different strengths have different product codes.
- **Package Code (2 digits)**: Identifies the package size and type (bottle of 30, bottle of 100, unit-dose blister pack, etc.).

### 10-Digit vs 11-Digit NDC Codes

While the official FDA format is 5-4-2 (11 digits), many systems display NDC codes as 10 digits using a 4-4-2, 5-3-2, or 5-4-1 format. To convert, add a leading zero to the short segment:
- 4-4-2 → add zero to labeler: 01234-5678-90
- 5-3-2 → add zero to product: 12345-0678-90
- 5-4-1 → add zero to package: 12345-6789-00

### NDC Swap Examples

1. **Lisinopril 10mg (manufacturer change)**: Wholesaler switches from Lupin (68180-0514-01) to Solco Healthcare (43547-0351-10). Same drug, completely different NDCs.
2. **Metformin 500mg ER (generic competition)**: 20+ different NDC codes from manufacturers including Amneal, Aurobindo, Mylan, Teva, Sun. A pharmacy may see 3-5 different NDCs for the same drug monthly.
3. **Omeprazole 20mg (package size change)**: Switching from 100-count to 1000-count bottles changes the package code, creating mismatches if matching on full 11-digit NDC.

### How RxDelta Handles NDC Swaps

RxDelta uses NDC family mapping to group all NDC codes for the same drug regardless of manufacturer. Instead of matching on the raw 11-digit NDC, RxDelta normalizes codes to identify therapeutically equivalent products. Only true discrepancies are flagged.

## Automated vs Manual Pharmacy Reconciliation

Independent pharmacies lose 2-5% of prescription revenue to billing discrepancies every month. The question isn't whether to reconcile  - it's whether to spend 4-6 hours doing it manually or 3 minutes with automation.

### Side-by-Side Comparison

| Feature | Manual (Spreadsheets) | Automated (RxDelta) |
|---|---|---|
| Time per reconciliation | 4-6 hours | Under 3 minutes |
| Accuracy | 85-92% (human error) | 98%+ match rate |
| NDC swap detection | Nearly impossible to spot manually | Automatic detection across all carriers |
| Insurance-level breakdown | Requires separate pivot tables per PBM | Built-in analytics by PBM, BIN, and carrier |
| Scalability | Each pharmacy adds 4-6 more hours | Same 3 minutes regardless of volume |
| Column header handling | Manual field mapping every time | Auto-detects 200+ header variations |
| Report generation | Manual chart/table creation | One-click PDF and CSV exports |
| Cost of errors | 2-5% of revenue lost to undetected discrepancies | Catches discrepancies before they compound |
| Staff requirement | Dedicated billing specialist | Any team member can run reports |
| Multi-pharmacy support | Separate spreadsheets per location | Unified dashboard for all locations |

### The Real Cost of Manual Reconciliation

A pharmacy technician earning $20/hour spending 6 hours on reconciliation costs $120 in direct labor  - but that's the small number. The real cost is the 2-5% of revenue that manual methods miss. For a pharmacy doing $300,000/month in prescription revenue, that's $6,000 to $15,000 per month in undetected discrepancies, NDC swaps, and PBM underpayments.

### NDC Swaps: The Hidden Revenue Killer

NDC swaps occur when the same medication is billed under different National Drug Code numbers due to manufacturer changes or wholesaler substitutions. A single drug like lisinopril 10mg can have over 30 different NDC codes from different manufacturers. Manual reconciliation can't reliably track these swaps across thousands of line items. Automated software resolves this by mapping NDC families and flagging true discrepancies.

## RxDelta vs Spreadsheet Reconciliation

Excel and Google Sheets are powerful general-purpose tools  - but pharmacy billing reconciliation requires specialized NDC knowledge, insurance analytics, and swap detection that spreadsheets weren't built for.

### Feature Comparison

| Feature | Excel / Google Sheets | RxDelta |
|---|---|---|
| NDC swap detection | Not possible without custom VBA macros | Automatic  - maps NDC families across manufacturers |
| File upload & parsing | Manual copy-paste, column alignment | Drag-and-drop with auto-header detection (200+ variations) |
| Processing time | 4-6 hours per pharmacy/month | Under 3 minutes per reconciliation |
| Insurance-level analytics | Requires manual pivot tables per PBM/BIN | Built-in breakdowns by PBM, BIN, and carrier |
| Error rate | 8-15% human error rate | Under 2% error rate |
| Report export | Manual formatting for PDF | One-click PDF and CSV exports |
| Multi-pharmacy | Separate files per location | Unified dashboard with group analytics |
| Data security | Depends on device security | AES-256 encryption, enterprise-grade |
| Setup cost | Free (Excel/Sheets license) | Starting at $200/month |

### The ROI Math

For a pharmacy with $350,000/month in prescription revenue using spreadsheets:
- Revenue lost to undetected discrepancies (3%): -$10,500/month
- Staff time for manual reconciliation (6 hrs × $22/hr): -$132/month
- Total monthly cost of spreadsheet approach: -$10,632/month
- RxDelta Data Access plan: $200/month
- Revenue recovered with 98% accuracy: +$10,290/month
- **Net monthly benefit: +$10,090/month**

## Pharmacy Glossary


**Pharmacy Billing Reconciliation**: The process of comparing pharmacy dispensing and billing records against purchase invoices and PBM remittance data to verify every prescription was billed correctly, reimbursed at the right amount, and that purchasing costs align with dispensing records.

**NDC Swap (NDC)**: When the same medication is billed under different National Drug Code (NDC) numbers in billing versus purchasing data, typically caused by manufacturer changes, wholesaler substitutions, or repackaging. NDC swaps create phantom shortages and surpluses that silently drain revenue.

**National Drug Code (NDC)**: A unique 11-digit identifier assigned to each medication in the United States, following the 5-4-2 format: 5 digits for the labeler (manufacturer), 4 digits for the product (strength, dosage form), and 2 digits for the package size. Required on all prescription drug labels by the FDA.

**PBM (PBM)**: Pharmacy Benefit Manager  - a third-party administrator that manages prescription drug benefits on behalf of health insurers, employer groups, and government programs. PBMs negotiate drug prices, process claims, and determine reimbursement rates for pharmacies.

**BIN Number (BIN)**: Bank Identification Number  - a 6-digit code on pharmacy benefit cards that identifies the PBM or claims processor responsible for adjudicating a prescription claim. Used to route claims to the correct payer during real-time adjudication.

**Claims Adjudication**: The real-time process by which a PBM evaluates a pharmacy claim at the point of sale to determine coverage, copay amount, and reimbursement. Adjudication checks patient eligibility, formulary status, drug interactions, prior authorizations, and pricing in milliseconds.

**Remittance**: The payment and associated documentation sent by a PBM or insurer to a pharmacy for processed claims. Remittance advice (RA) details each claim paid, the reimbursement amount, any adjustments, and the total payment. Comparing remittance data against billing records is essential for reconciliation.

**DIR Fees (DIR)**: Direct and Indirect Remuneration fees  - retroactive charges imposed by PBMs on pharmacies, typically assessed after the point of sale based on performance metrics or contractual terms. DIR fees reduce the effective reimbursement pharmacies receive and can turn profitable prescriptions into losses.

**Variance**: The numerical difference between expected and actual values in pharmacy billing reconciliation. A positive variance (surplus) means more units were purchased than billed; a negative variance (shortage) means more units were billed than purchased. Variances indicate potential billing errors, theft, or data entry mistakes.

**Shortage**: A reconciliation result where the billed quantity for a drug exceeds the purchased quantity, indicating more was dispensed than acquired. Shortages may result from unrecorded purchases, NDC swaps, theft, or billing errors. Persistent shortages signal revenue leakage.

**Overage**: A reconciliation result where the purchased quantity for a drug exceeds the billed quantity, meaning more was bought than dispensed. Overages may indicate unbilled prescriptions, data entry errors, or inventory accumulation. Significant overages represent tied-up capital.

**AWP (AWP)**: Average Wholesale Price  - a benchmark price for prescription drugs published by pricing compendia like Medi-Span and First Databank. Often called the 'sticker price' of drugs, AWP serves as the basis for many PBM reimbursement calculations (e.g., AWP minus a percentage discount).

**WAC (WAC)**: Wholesale Acquisition Cost  - the manufacturer's list price to wholesalers, before any discounts or rebates. WAC is considered a more transparent benchmark than AWP and is increasingly used as the basis for drug pricing and reimbursement calculations.

**MAC Pricing (MAC)**: Maximum Allowable Cost  - the highest reimbursement amount a PBM will pay for a generic or multi-source drug. MAC lists are created by PBMs and may not reflect actual pharmacy acquisition costs, often resulting in below-cost reimbursements for independent pharmacies.

**Formulary**: A list of prescription drugs covered by a health plan or PBM, typically organized into tiers that determine patient copay amounts. Tier 1 (preferred generics) has the lowest copays, while higher tiers (specialty, non-preferred brands) have higher costs. Formulary placement significantly affects prescription volume.

**Prior Authorization (PA)**: A requirement by the PBM or health plan that a prescriber obtain approval before a specific medication will be covered. Prior authorizations are used for high-cost drugs, non-preferred medications, and specialty therapies. They add administrative burden and can delay patient access.

**340B Program (340B)**: A federal drug pricing program (Section 340B of the Public Health Service Act) that requires drug manufacturers to provide outpatient drugs at significantly reduced prices to eligible healthcare organizations (covered entities). 340B pricing can be 25-50% below AWP.

**NCPDP (NCPDP)**: National Council for Prescription Drug Programs  - the standards organization that creates and maintains the electronic data interchange standards used in pharmacy claims processing. The NCPDP Telecommunication Standard (D.0) is the universal format for real-time pharmacy claims.

**Third-Party Payer**: Any entity other than the patient that pays for prescription drug costs, including commercial insurers, PBMs, Medicare Part D plans, Medicaid, and employer-sponsored health plans. In the U.S., third-party payers cover approximately 90% of all prescription transactions.

**Copay (Copay)**: A fixed dollar amount a patient pays out-of-pocket for a prescription at the point of sale. Copay amounts are determined by the drug's formulary tier and the patient's health plan. Common copay structures: $10 for Tier 1 generics, $35 for Tier 2 preferred brands, $75+ for Tier 3 non-preferred.

**Coinsurance**: A percentage of the prescription drug cost that the patient pays out-of-pocket (e.g., 20% coinsurance means the patient pays 20% and the insurer pays 80%). More common for specialty drugs and higher formulary tiers than flat copays.

**Deductible**: The amount a patient must pay out-of-pocket for prescription drugs before their insurance coverage begins. During the deductible phase, the patient pays the full negotiated price. Common pharmacy deductibles range from $250 to $2,000 per year.

**GER (GER)**: Generic Effective Rate  - a metric that measures the average reimbursement a pharmacy receives for generic drugs as a percentage of a benchmark price (usually AWP). Used to evaluate PBM contract competitiveness. A GER of AWP-85% means the pharmacy is reimbursed at 15% of AWP.

**Generic Substitution**: The practice of dispensing a generic equivalent instead of a brand-name drug. State laws regulate when substitution is permitted. Generic substitution increases pharmacy margins (generics typically have higher markups) and reduces costs for patients and insurers.

**DAW Code (DAW)**: Dispense As Written  - a code on a prescription claim that indicates whether brand or generic substitution was requested. DAW 0 means substitution is allowed; DAW 1 means the prescriber requested brand only; DAW 2 means the patient requested brand. DAW codes affect reimbursement and patient cost.

**PCN (PCN)**: Processor Control Number  - an additional identifier on pharmacy benefit cards used alongside the BIN number to route claims to the correct processor or plan within a PBM. The BIN identifies the PBM, while the PCN identifies the specific processing path.

**Group Number**: An identifier on a pharmacy benefit card that specifies the employer group or plan under which the patient is covered. Used during claims adjudication to determine the correct formulary, copay structure, and network rules for the claim.

**Acquisition Cost**: The actual price a pharmacy pays to purchase a drug from a wholesaler or manufacturer, including all discounts and rebates. Actual acquisition cost (AAC) is the most accurate measure of pharmacy drug costs and is increasingly used by state Medicaid programs for reimbursement.

**U&C Price (U&C)**: Usual and Customary Price  - the cash price a pharmacy charges to a customer without insurance. PBMs reimburse at the lower of the contracted rate or the U&C price. Pharmacies must report accurate U&C prices; inflated prices can trigger audits and penalties.

**Clawback**: When a PBM retroactively recovers money from a pharmacy after the point of sale. Clawbacks occur through DIR fees, audit recoveries, or pricing adjustments. They reduce the pharmacy's effective reimbursement below what appeared at the time of dispensing.

**Step Therapy**: A utilization management protocol requiring patients to try one or more lower-cost medications before the PBM will cover a higher-cost alternative. Also called 'fail first' policies. Common in managing high-cost therapeutic categories.

**Dispensing Fee**: The professional fee paid to a pharmacy for each prescription dispensed, separate from the drug ingredient cost. Dispensing fees cover the pharmacist's professional services, overhead, and operational costs. Typical dispensing fees range from $1 to $15 depending on the payer.

**ERA (ERA)**: Electronic Remittance Advice  - the electronic version of a payment explanation sent from a PBM or insurer to a pharmacy. ERAs detail each claim's reimbursement, adjustments, and denial reasons, enabling automated posting of payments to pharmacy management systems.

**Inventory Management**: The systematic process of ordering, storing, tracking, and dispensing pharmaceutical inventory. Effective inventory management minimizes carrying costs, reduces expired product waste, ensures adequate stock levels, and supports accurate reconciliation.

**Wholesaler**: A pharmaceutical distributor that purchases drugs from manufacturers and sells them to pharmacies, hospitals, and other healthcare facilities. The three largest wholesalers (McKesson, AmerisourceBergen/Cencora, Cardinal Health) distribute approximately 90% of all pharmaceuticals in the U.S.

**PBM Audit**: A review of pharmacy records conducted by or on behalf of a PBM to verify the accuracy of claims submitted. Audits check prescription validity, dispensing records, pricing accuracy, and regulatory compliance. Failed audits can result in financial recoupments and network termination.

**Reimbursement**: The payment a pharmacy receives from a PBM, insurer, or government program for dispensing a prescription. Reimbursement typically equals the ingredient cost (based on AWP, WAC, or MAC) plus a dispensing fee, minus the patient's copay. The difference between reimbursement and acquisition cost determines pharmacy margin.

**Point of Sale (POS)**: The moment when a prescription is processed and adjudicated in real time at the pharmacy counter. POS adjudication occurs via electronic communication between the pharmacy system and the PBM, determining coverage, copay, and reimbursement within seconds.

**Carrier**: The insurance company or entity that provides the pharmacy benefit to the patient. In claims processing, the carrier is identified by the BIN number on the benefit card. Multiple carriers may use the same PBM for claims processing.

**Labeler Code**: The first 5 digits of a National Drug Code (NDC) that identify the manufacturer, repackager, or distributor of the drug. Assigned by the FDA. Each labeler receives a unique code; changes in labeler codes are a primary cause of NDC swaps during reconciliation.

**Pharmacy Management System (PMS)**: Software used by pharmacies to manage dispensing operations, patient records, claims processing, inventory, and reporting. Common systems include PrimeRx, Liberty, Pioneer, Rx30, Computer-Rx, and BestRx. Data exported from these systems is used for billing reconciliation.

**PrimeRx**: A widely-used pharmacy management system developed by Micro Merchant Systems, popular among independent pharmacies. PrimeRx handles dispensing, claims adjudication, inventory management, and reporting. Its CSV export format is commonly used for reconciliation workflows.

**Therapeutic Equivalence**: The FDA designation that two drug products contain the same active ingredient, dosage form, strength, and route of administration, and are expected to produce the same clinical effect. Therapeutically equivalent drugs may have different NDC codes, which can cause NDC swap issues in reconciliation.

**Narrow Network**: A pharmacy network created by a PBM that limits the number of participating pharmacies, often excluding independent pharmacies in favor of chain or PBM-owned pharmacies. Narrow networks reduce patient choice but can lower costs for the plan sponsor.

**Spread Pricing**: A PBM practice where the PBM charges the health plan a higher price for a drug than it reimburses the pharmacy, keeping the difference (the 'spread') as profit. Spread pricing is increasingly criticized for lack of transparency and has been banned by several states.

**Medication Adherence**: The extent to which patients take medications as prescribed by their healthcare providers. Measured by metrics like PDC (Proportion of Days Covered) and MPR (Medication Possession Ratio). PBMs use adherence metrics in quality programs and DIR fee calculations.

**Star Ratings**: CMS (Centers for Medicare and Medicaid Services) quality ratings for Medicare Part D plans, scored 1-5 stars. Pharmacy performance metrics like medication adherence and generic dispensing rates contribute to plan Star Ratings. Higher ratings result in bonuses; lower ratings can trigger penalties.

**Specialty Pharmacy**: A pharmacy that dispenses high-cost, complex medications requiring special handling, storage, or patient monitoring. Specialty drugs often cost $1,000+ per month and treat conditions like cancer, rheumatoid arthritis, and multiple sclerosis. Specialty pharmacy represents over 50% of total drug spending.

**Revenue Leakage**: Revenue that a pharmacy should have collected but didn't due to billing errors, PBM underpayments, undetected NDC swaps, missed claims, or uncollected copays. Revenue leakage is often invisible without systematic reconciliation and typically represents 2-5% of prescription revenue for independent pharmacies.

**Batch Reconciliation**: The process of reconciling pharmacy billing data in bulk, typically covering a specific time period (weekly, monthly, or quarterly). Batch reconciliation compares aggregate billing and purchasing data rather than individual transactions, identifying patterns and trends across thousands of claims simultaneously.

**Drug Utilization Review (DUR)**: A program that evaluates prescription drug use to ensure medications are appropriate, medically necessary, and unlikely to cause adverse effects. DUR checks occur during claims adjudication (prospective DUR) and through retrospective analysis of claims data.

**Multi-Source Drug**: A drug available from multiple manufacturers, typically a generic drug produced by several generic companies. Multi-source drugs are subject to MAC pricing by PBMs and are a common source of NDC swaps because each manufacturer's version carries a different NDC.

**Pass-Through Pricing**: A PBM pricing model where the health plan pays the pharmacy the exact same amount the PBM reimburses, plus a transparent administrative fee. Eliminates spread pricing. Increasingly demanded by employers and legislated by states seeking PBM transparency.

**Pharmacy Claims Data**: The electronic records generated when prescriptions are adjudicated, containing the drug NDC, quantity, days supply, prescriber, patient, payer, reimbursement amount, and copay. Claims data is the foundation of pharmacy billing reconciliation and analytics.
