Explanation:

The CMS - 1500 claim form is used for billing physician and non - institutional services. The ANSI ASC X12N 837 (specifically the 837P version within the ANSI ASC X12N 837 family) is the flat - file format that corresponds to the CMS - 1500 claim form for professional (physician and non - institutional) services. NSF is the National Science Foundation (unrelated to billing formats). UB - 04 is used for institutional (hospital) billing. NDC is the National Drug Code (used for identifying drugs, not billing service formats).

Answer:

C. ANSI ASC X12N 837
