OA-258: Claim Not Covered - Patient in Custody or Incarcerated

What Does OA-258 Mean?

When paired with Group Code OA, CARC 258 typically appears in a secondary payer or coordination of benefits context. The adjustment for claim not covered - patient in custody or incarcerated is being processed through COB rules. The financial responsibility depends on the specific coordination arrangement between payers.

CARC 258 appears when a payer denies a claim because the patient was identified as being in custody or incarcerated at the time the service was rendered. Under most insurance policies, Medicaid rules, and commercial plan terms, coverage is suspended or excluded during periods of incarceration because the custodial authority — the federal Bureau of Prisons, state Department of Corrections, or local jail system — assumes responsibility for the inmate's healthcare.

The most common trigger is the federal Medicaid inmate exclusion, which prohibits Medicaid payment for services provided to incarcerated individuals. Some states allow an exception for inpatient hospital stays of 24 hours or more, but outpatient services are generally excluded. Commercial insurers may also have policy provisions that suspend coverage during custody periods.

CARC 258 appears with Group Code CO, indicating the denial is a contractual adjustment. However, the resolution path depends on whether the patient was actually in custody. If the patient was not incarcerated on the date of service — perhaps they had been released before the encounter or the payer's data is outdated — the provider should appeal with documentation proving the patient's non-custody status. If the patient was genuinely incarcerated, the provider should submit the claim to the responsible government custodial authority.

How to Resolve

1. Review the coordination of benefits Examine the OA-258 adjustment and determine how it fits within the primary/secondary payer relationship.
2. Verify primary payer adjudication Review the primary payer's EOB to understand the basis for the secondary payer's OA adjustment.
3. Determine appropriate action Based on the COB review, decide whether to accept the adjustment, submit additional documentation, or file an appeal with the secondary payer.
4. Follow up Monitor the claim and take additional action as needed based on the COB determination.

How to Prevent OA-258

• Maintain current coordination of benefits information for patients with multiple insurance plans
• Submit complete documentation including primary payer EOBs when filing secondary claims
• Verify secondary payer requirements before claim submission
• Track OA adjustment patterns to identify systemic COB issues
