Availity Claim Status API

The Availity Claim Status API enables the standard ASC X12N 276 and 277 transactions, allowing providers to find, create, and manage claim status inquiries against payer systems. REST APIs bridge provider billing systems and payers through the Availity clearinghouse network. Supports both standard 276/277 workflows and enhanced claim status with summary and detail search.
