PCM mapping: One PCM stores all APC mapping; each APC will need a PCD.

PCM mapping: One PCM stores all APC mapping; each APC will need a PCD.

• A. One PCM stores all APC mapping; each APC will need a PCD.
• B. Each APC requires its own PCM.
• C. PCM stores mapping for only some APCs.
• D. PCM is deprecated.

Answer: (A)

Centralizing APC mappings in a single PCM provides a single source of truth for how ambulatory services are categorized for payment. Each APC needs a PCD because the PCD holds the actual procedure code data—codes, descriptions, and related metadata—that defines what the APC covers. With one PCM handling all APC mappings, changes in coding rules or reimbursement logic apply uniformly to every APC. Each APC having its own PCD keeps the detailed code information organized and directly linked to that APC, avoiding duplication and confusion. This setup ensures consistency and scalability, whereas splitting mappings across multiple PCM stores or leaving some APCs unmapped would create gaps and inconsistencies.
