OA-277: Claim Undetermined During Premium Grace Period (SHOP)

What Does OA-277 Mean?

OA-277 indicates a temporary adjustment during the premium payment grace period under the SHOP Exchange. The claim is not permanently denied — it is in a holding pattern while the payer waits to confirm premium payment. Once the grace period resolves, the claim will be reprocessed or the coverage will terminate.

CARC 277 is a temporary hold, not a permanent denial. It appears when a claim is submitted during the premium payment grace period for a plan purchased through the Health Insurance SHOP (Small Business Health Options Program) Exchange. The payer cannot process the claim because it is waiting to confirm whether the patient's employer or the patient paid the insurance premium on time.

The 31-day SHOP grace period creates a coverage limbo where the payer holds claims rather than adjudicating them. Once the grace period concludes — either because the premium was paid or because non-payment was confirmed — the claim will be automatically reprocessed. If the premium was paid, the claim processes normally. If coverage terminated due to non-payment, the provider will need to bill the patient directly.

This code is exclusively used with Group Code OA and is specific to SHOP Exchange plans. It differs from standard eligibility denials because the coverage is not yet determined — it is genuinely pending rather than denied.

How to Resolve

Monitor the claim during the grace period, verify premium payment status with the payer, and take appropriate action once the status is determined.

1. Verify the grace period Confirm the claim is held due to the 31-day SHOP Exchange premium grace period by reviewing the remittance details.

3. Wait for automatic reprocessing The claim should be automatically reprocessed once the grace period concludes and premium status is confirmed.
4. Request manual reprocessing if needed If the premium was paid but the claim was not reprocessed, contact the payer to request manual reprocessing.
5. Bill patient if coverage terminated If the premium was not paid and coverage is terminated, bill the patient directly for the full amount.
