What information does the Payment Classification Definition (PCD) record define?

• A. The plan's eligibility rules.
• B. The patient demographic details.
• C. The information needed for the rate x weight calculation for each APC.
• D. The claim submission timeline.

Answer: (C)

The Payment Classification Definition captures the inputs that determine how APC payments are calculated. It maps a set of service characteristics (like CPT/HCPCS codes, revenue codes, and modifiers) to a specific APC and its relative weight, then defines the base rate so the payment can be computed as rate times weight for that APC. This is exactly what the question refers to when it mentions the information needed for the rate × weight calculation for each APC. It’s not about who is eligible, patient demographics, or when a claim must be submitted, which are outside of how APC payments are calculated.
