Module 7: Billing, Coding & Reimbursement

Mastering the Financial Engine of Specialty Pharmacy Operations.

From Clinical Care to Cash Flow: Understanding the Business Side

You have mastered the intricacies of clinical management, navigated the complex labyrinth of patient access, and become an expert financial shield for your patients. Now, we shift focus to the operational backbone that makes specialty pharmacy possible: the intricate world of billing, coding, and reimbursement.

As a community pharmacist, you were largely insulated from this. Claims were submitted, adjudicated in seconds, and payment (however meager) arrived weeks later. In specialty, particularly within hospitals, health systems, or independent practices, the pharmacist is deeply embedded in the revenue cycle. Understanding how claims are coded, submitted, denied, appealed, and ultimately paid is not just an administrative task—it is fundamental to the financial viability of your service and your ability to care for patients.

This module translates your existing knowledge of NDCs and basic billing into the complex language of medical coding (HCPCS, CPT), revenue codes, complex billing models like “buy-and-bill,” and the strategies needed to fight for every dollar of reimbursement. You will learn to think like a revenue cycle manager, identifying potential denial pitfalls before they happen, crafting powerful appeals, and understanding the opaque world of DIR fees and payer reconciliation. This is the business side of saving lives, and mastering it is essential for the advanced specialty practitioner.

Your Guide to the Reimbursement Landscape

This module demystifies the complex financial operations that underpin specialty pharmacy practice.

7.1 HCPCS, NDC, CPT, and Revenue Code Integration

Decoding the alphabet soup of medical billing codes. Learn how drug (NDC), procedure (CPT), supply (HCPCS), and location (Revenue Code) codes must integrate seamlessly for successful medical benefit claims.

7.2 Buy-and-Bill, White Bagging, Brown Bagging Models

Mastering the different specialty drug procurement and delivery models. Understand the financial risks and operational workflows of provider-administered (“buy-and-bill”) vs. pharmacy-dispensed (“white/brown bagging”) therapies.

7.3 Denial Prevention and Appeal Strategy

Transforming denials from frustrating roadblocks into solvable problems. Learn proactive strategies to prevent common billing denials and master the art of writing compelling, evidence-based appeals for overturned decisions.

7.4 DIR/GER/GCR Fees and Payer Reconciliation

Unmasking the hidden costs of pharmacy reimbursement. Understand the complex and often opaque world of Direct/Indirect Remuneration (DIR), Generic Effective Rates (GER), and payer “clawbacks,” and learn strategies for reconciliation.

7.5 Revenue Cycle Management and KPI Tracking

Thinking like a pharmacy manager. Learn the fundamentals of the revenue cycle, from intake to cash collection, and understand the Key Performance Indicators (KPIs) used to measure the financial health of a specialty pharmacy service.
