OA-273: Coverage/Program Guidelines Exceeded
Coverage limits were exceeded under an other adjustment. Check if a secondary payer can cover the excess.
What Does OA-273 Mean?
OA-273 indicates the excess coverage adjustment involves coordination of benefits or falls outside standard contractual and patient responsibility categories. A secondary payer may need to evaluate the excess amount.
When CARC 273 appears on a remittance, the payer is indicating that the billed service went beyond the limits established in the patient's coverage or program guidelines. Unlike CARC 272 (guidelines not met), CARC 273 specifically signals that a maximum was reached or surpassed. The service itself may be covered in principle, but the patient has exhausted their available benefits for that service type — whether measured in visit counts, units, dollar amounts, or time periods.
This denial is common in rehabilitation services (physical therapy, occupational therapy, speech therapy), behavioral health, chiropractic care, and any specialty where payers impose visit limits or benefit caps. For example, a plan may cover 20 physical therapy visits per calendar year — visit 21 triggers CARC 273. Similarly, a plan may limit the number of units of a specific drug or supply, and billing beyond that cap results in this adjustment.
The group code is critical for determining your next step. Under CO, the excess amount is a contractual write-off that the provider absorbs. Under PR, the patient is responsible for the overage. In both cases, there may be an opportunity to appeal if the additional services were medically necessary. Many payers have exception processes where a provider can request additional visits or units beyond the standard cap by submitting clinical documentation demonstrating ongoing medical need. The key is to request these exceptions proactively — ideally before the patient reaches the benefit limit — rather than retroactively after a denial.
How to Resolve
Verify the benefit limit that was exceeded, confirm coding accuracy, and appeal with medical necessity documentation if the additional services were clinically required.
- Identify secondary coverage Check the patient's records for secondary insurance that may cover services beyond the primary plan's limits.
- Submit to the secondary payer Forward the excess charges to the secondary payer with the primary remittance showing the OA-273 adjustment.
How to Prevent OA-273
- Verify all insurance coverage at intake to ensure claims exceeding primary plan limits are properly routed to secondary payers
- Track OA adjustments for systematic routing to secondary payer workflows
General Prevention
- Verify the patient's remaining benefit limits and coverage caps before rendering services
- Obtain prior authorization when approaching plan limits to confirm coverage for additional services
- Track patients' utilization against their plan limits throughout the benefit period
- Maintain clear communication with patients about their remaining covered benefits before scheduling additional services
- Review payer coverage guidelines regularly to stay current with frequency limits, unit caps, and benefit maximums
- Implement billing system alerts that flag when a patient is approaching or has exceeded their coverage limits
