Which two coding elements identify the provider and the provider's specialty on a claim?

• A. CPT and ICD-10-CM codes.
• B. DRG and APC.
• C. NPI and taxonomy codes.
• D. RA and EOB.

Answer: (C)

The concept being tested is how a claim identifies who provided the service and what their specialty is. The best answer uses the National Provider Identifier (NPI) together with taxonomy codes. The NPI is a unique, 10-digit identifier assigned to each individual or organization that provides healthcare services, and it is used in almost all HIPAA-standard transactions to clearly identify who rendered the service. The taxonomy code describes the provider’s professional classification and area of specialty (for example, family medicine, cardiology, pediatrics). While the NPI tells you who the provider is, the taxonomy code tells you what kind of specialist they are, and together they help payers route the claim correctly, confirm credentials, and understand the context of the encounter. Other options don’t fit because CPT and ICD-10-CM codes describe what was done and why (procedures and diagnoses), not who did it or their specialty. DRG and APC group patients for payment purposes, not provider identity. RA and EOB are remittance documents, not identifiers of the provider or their specialty.
