What is the primary purpose of payer edits (such as LCDs and CCI edits) in medical coding?

• A. Flag inappropriate code combinations
• B. Determine DRG/APC
• C. Calculate patient eligibility
• D. Identify denials

Answer: (A)

Payer edits focus on enforcing proper coding to ensure claims reflect the actual services and aren’t paid incorrectly. LCDs (Local Coverage Determinations) tell a particular payer what they will cover in specific situations, but the key worker in coding workflows is the set of edits that check code pairs. CCI edits, in particular, compare CPT/HCPCS code pairs and flag or adjust payments when two codes should not be billed together or when one code typically includes another. This helps prevent unbundling, duplicate billing, and improper payments, and supports compliance and audit readiness. They aren’t about determining DRG or APC assignments, which are used for payment classification, nor about deciding patient eligibility. If a prohibited pairing is billed, a denial can occur, but the central purpose of these edits is to catch and prevent inappropriate code combinations before payment is issued.
