Final answer:
The CMS-1500 is the standard form for billing provider fee-for-service claims to commercial health insurance companies, while other forms like UB-04 and ANSI ASC X12N have specific uses.
Step-by-step explanation:
For billing provider fee-for-service claims to commercial health insurance companies, the standard claim form used is the CMS-1500. It's a standardized form used by Medicare and health insurance providers to submit claims for medical services. The other claim forms such as UB-04 and ANSI ASC X12N have their specific uses; UB-04 is commonly used by institutions like hospitals for inpatient and outpatient billing, while ANSI ASC X12N (also known as EDI Health Care Claim Transaction set 837) is used for electronic billing. The CMS-1450 is another name for the UB-04 form and is not generally used for professional fee-for-service billing.
