Which document is primarily used by physicians to bill for services rendered?

The CMS-1500 form is primarily used by physicians and other health care providers to submit claims for reimbursement for services rendered to patients. This form is standardized and widely accepted by various insurance carriers for processing professional medical claims.

The CMS-1500 captures essential information such as the patient's demographic details, insurance information, diagnosis codes, and procedure codes, which are critical for accurately billing and receiving payment from insurance companies.

While the UB-04 form is used mainly by hospitals and other institutional providers to bill for facility services, and the healthcare claim form might refer to various types of claims processing forms, the term "superbill" typically refers to an internal document used by physicians that lists services rendered but isn't submitted directly to insurers. Each of these alternatives has specific contexts and uses, but the CMS-1500 is the primary form for individual physicians to bill for their services.
