Final answer:
Submit electronic claims to a third-party payer using CMS-1500, UB-04, or 837P formats; CMS-1500 for multiple health care services, UB-04 mainly by hospitals, and 837P for electronic data interchange. The 276/277 transactions are for claim status updates, not billing.
Step-by-step explanation:
The formats used to submit electronic claims to a third-party payer include CMS-1500, UB-04, and 837P. The CMS-1500 is a standard form used in the healthcare industry to bill Medicare and Medicaid, as well as private insurers for healthcare services. The UB-04 form, also known as the CMS-1450, is another format which is used by hospitals to bill for inpatient and outpatient services. The 837P (Professional) is an electronic data interchange (EDI) format adopted as the standard for transmitting healthcare services information. This includes billing information from healthcare providers to payers, such as insurers or health maintenance organizations (HMOs). Conversely, the 276/277 are not specifically used for billing; instead, they are transactions primarily used for getting claim status updates from payers.
