Block 24a contains which codes?

• A. Diagnosis codes
• B. Place of service codes
• C. Modifiers
• D. Billing charges

Answer: (B)

Block 24a captures the place-of-service code for each service line. This code tells the payer where the service actually took place, such as a physician’s office, an outpatient department, or another care setting. The setting matters because reimbursement rules and rates often differ by location, so coding the exact place of service ensures the claim is processed with the correct payment level. This is separate from diagnosis information, which describes the patient’s condition, and from CPT/HCPCS procedure codes (and any modifiers) that describe what was done, as well as the charges, all of which appear in other parts of the claim. In short, block 24a communicates the context of care location, which directly influences payment.
