Key Takeaways Explain This Topic AI

Third-party insurance requires BIN, PCN, Group ID, and Member ID for processing.

Common rejection codes: NDC not covered, quantity limits exceeded, refill too soon, prior authorization required.

Copays vary by formulary tier: generic (lowest), preferred brand, non-preferred brand, specialty (highest).

Prescription transfers require specific information and documentation per state law.

Prior authorization (PA) is needed when insurance requires prescriber justification before covering a medication.

Last updated: November 2026

Quick Answer: Insurance claims require BIN (Bank Identification Number), PCN (Processor Control Number), Group ID, and Member ID. Common rejections include NDC not covered, refill too soon, and prior authorization required. Copays are based on formulary tiers, with generics typically having the lowest copay.

Outline note: Insurance billing is not one of the Order Entry and Processing knowledge areas on PTCB's January 2026 PTCE outline (4.1 calculations and sig codes, 4.2 administration supplies, 4.3 lot numbers, expiration dates and NDCs, 4.4 returns). PTCB's CPhT Knowledge Reference lists third-party billing information as required background, so study this section as job background.

Understanding insurance billing and prescription processing is essential for pharmacy technicians. This section covers third-party billing, common rejection codes, copays, prior authorizations, and prescription transfers.
