What is an 837P electronic claim?
The 837P is the standard electronic professional claim format used by health care professionals and suppliers. It serves the electronic professional-claim workflow that corresponds broadly to information submitted on the CMS-1500 paper claim form.
CMS identifies ANSI ASC X12N 837P Version 5010A1 as the current electronic professional claim version. Payers, Medicare Administrative Contractors, clearinghouses, and billing services may also have enrollment, connectivity, companion-guide, and other submission requirements.
Important distinction: MedClaimSoftware creates the 837P file. The actual transmission step happens outside the program through the submission route you use.

Do I need a clearinghouse?
That depends on the payer and the electronic connection available to you. Some organizations submit through a clearinghouse or billing service; Medicare professional claims may involve a Medicare Administrative Contractor and EDI enrollment/connectivity requirements. The 837P software does not replace those arrangements—it creates the claim file used in the workflow.
