OA-190: Billing for SNF Qualified Stay Already Covered
The SNF billing issue appeared during coordination of benefits. Determine which payer's rules apply.
What Does OA-190 Mean?
With OA (Other Adjustments), the SNF consolidated billing issue was flagged during coordination of benefits. Review the COB details and determine which payer applies the SNF billing rules.
CARC 190 indicates that the service billed was rendered to a patient during a qualifying Skilled Nursing Facility (SNF) stay, and under Medicare's SNF Consolidated Billing rules, the service is bundled into the SNF's per diem payment. Outside providers cannot bill Medicare separately for services that fall within SNF consolidated billing — they must bill the SNF directly.
SNF consolidated billing covers most services provided during a qualifying stay, including therapy services (PT, OT, speech), laboratory tests, certain diagnostic services, DME, and supplies. However, specific services are excluded from consolidated billing and can be billed separately, such as certain physician services, dialysis, and some high-cost procedures. The key is determining whether the specific service falls within or outside the consolidated billing rules.
How to Resolve
- Review COB details Determine which payer in the coordination chain applied the SNF consolidated billing rule.
- Verify the SNF stay status Confirm whether the patient had a qualifying SNF stay.
- Coordinate billing accordingly Bill the SNF directly or appeal to the appropriate payer.
Billing for SNF Qualified Stay Already Covered grouped under OA is an Other Adjustment that doesn't fall into the standard contractual write-off or patient responsibility categories. Whether action is needed depends on the specific reason — review any accompanying RARC codes and payer guidance to decide whether this is a final adjustment to accept or an issue to resolve through resubmission.
