Which CPT or HCPCS codes are entered in Block 24D?

Block 24D on the CMS-1500 form is specifically designated for reporting procedures, services, and supplies rendered to the patient. This includes the appropriate Current Procedural Terminology (CPT) codes or Healthcare Common Procedure Coding System (HCPCS) codes that describe the medical services or procedures performed during the patient’s visit. Including these codes is essential as they provide detailed information to the insurance company about the nature of the services billed, which is crucial for the claims process.

Modifiers, which can indicate specific circumstances surrounding the procedures or services provided, are sometimes included in Block 24D, but they are secondary to the primary codes representing the procedures themselves. Diagnosis codes have their own specific section on the CMS-1500 form, typically recorded in Block 21, and patient demographic information is entered in separate blocks meant for that information. The integrity of the billing process relies on accurately reporting the procedures performed, making this answer the correct choice for Block 24D.
