CO-97 — Bundled — included in another adjudicated service
Claim-adjustment reason code 97 · typically reported as CO-97
What it means
Payment for this line is considered part of another service already paid. On practitioner claims this is typically an NCCI procedure-to-procedure (PTP) edit; DME supplier claims have no NCCI PTP table, so for DME it reflects a payment rule that includes the item in another allowance.
Why DME claims hit it
- Supplies billed separately that are included in the device allowable
- Accessory or option billed separately when the DME MAC policy includes it in the base item allowance
- Repair parts billed during a rental period (maintenance is in the rental payment)
How to fix it
- Check the DME MAC policy article for what the base item allowance includes; if the item is separately payable and documented, correct and resubmit
- If truly bundled, write off and stop billing the component separately
Appeal posture
Only when the policy makes the item separately payable and documentation supports it.
