CO-202: Non-Covered Personal Comfort or Convenience Services

What Does CO-202 Mean?

CO-202 means the payer has denied the service as a non-covered personal comfort item and the provider must absorb the adjustment. Under CO, the provider cannot transfer this balance to the patient. This typically occurs when no ABN was obtained before delivering the comfort service, or when the payer contract specifically excludes the service category. The only recourse under CO is to appeal if you have clinical documentation supporting medical necessity.

CARC 202 denies payment because the payer has determined that the billed service falls into the category of personal comfort or convenience rather than medical necessity. This classification covers items and services that make the patient more comfortable but are not required for their clinical care — private rooms when a semi-private room is available and clinically adequate, television or phone rentals, guest meals, cosmetic enhancements, and similar amenities.

The critical distinction with CARC 202 is between genuine comfort items and services that appear to be comfort items but have a legitimate clinical justification. A private room requested for patient preference is a comfort item. A private room required for airborne infection isolation is medically necessary. The difference lies entirely in the clinical documentation — if the physician documented the medical reason for the service, the denial can often be overturned on appeal.

For Medicare claims, the Advance Beneficiary Notice (ABN) is central to how this denial is resolved. If an ABN was issued before the service and the patient signed it acknowledging potential non-coverage, the provider can bill the patient under PR. If no ABN was obtained, the provider typically must absorb the cost under CO. This makes proactive identification of potentially non-covered comfort services and timely ABN issuance essential to financial protection.

Common Causes

How to Resolve

Determine whether the service was medically necessary or truly a comfort item, then appeal with documentation or bill the patient based on ABN status.

1. Evaluate medical necessity Review the clinical documentation to determine if the service had a legitimate clinical purpose. A private room for MRSA isolation, for example, is not a comfort item.
2. Appeal with clinical documentation If medical necessity exists, submit an appeal with physician orders, clinical notes, infection control documentation, or other evidence demonstrating that the service was required for the patient's clinical care.
3. Verify ABN status If the service is a true comfort item, check whether an ABN was obtained. If yes, you may be able to rebill under PR with the GA modifier (ABN on file) instead of absorbing the write-off.
4. Post as contractual write-off if no ABN If no ABN was obtained and the service is genuinely non-covered, post the amount as a contractual write-off and update your processes to capture ABNs for similar services going forward.

Common RARC Pairings

The RARC code tells you exactly what triggered the CO-202:

How to Prevent CO-202

• Maintain a list of services commonly classified as personal comfort or convenience by each major payer and ensure ABNs are issued for all such services
• Document the clinical necessity for any service that could be misclassified as a comfort item at the time the service is ordered — not after the denial
• Implement a pre-billing review for facility charges commonly associated with CARC 202 (private rooms, special accommodations, non-standard supplies)
• Train physicians and clinical staff to include specific clinical justification in their orders when requesting services that could be deemed comfort items

General Prevention

• Maintain an up-to-date list of services classified as personal comfort or convenience by each major payer
• Obtain an Advance Beneficiary Notice (ABN) before providing any service that may be classified as personal comfort or convenience
• Document the medical necessity for services that could be misclassified as comfort items (e.g., private room for isolation, special diet for clinical reasons)
• Train billing staff to use appropriate modifiers and coding when billing services that border between medical necessity and comfort
• Implement pre-billing review for facility charges that commonly trigger CARC 202 (private rooms, special accommodations, non-standard supplies)
