Denial code 97CO-97: Bundled into another procedure
Included in the payment for another service (bundled).
What to doAppeal with evidence
Often recoverableYes, when worked
The letters in front matter. CO means the office can't bill the patient for the amount; PR means the patient may owe it. The same number can appear with either, so read both parts.
Why dental offices see it
- The insurer treats the service as part of another one done the same day (for example a buildup or a palliative treatment).
- Two codes were billed that the plan considers one service.
What to do
- Check whether the services were truly separate and distinct.
- If they were, appeal with notes and x-rays showing each one.
- If not, the bundled amount is usually a write-off under a PPO contract.
Stop it next time
Know which procedure pairs each insurer bundles, and document separate services clearly.
