CO-112Contractual ObligationDocumentation
CO-112 Denial Code: Service not furnished directly / not documented
The payer concluded the service wasn't personally furnished to the patient or isn't supported in the record — an audit-flavored denial.
Why CO-112 happens
- ●Incident-to or supervision requirements not met
- ●Documentation doesn't show the billed service actually occurred
How to fix a CO-112 denial
- 1
Appeal with records proving who performed the service and how
- 2
If supervision rules were genuinely missed, write off and fix the workflow — do not rebill under another provider
How to prevent it
Audit incident-to and split/shared visit compliance quarterly.
