Quick Explanation
This denial indicates that the payer determined the billed service was not provided directly to the patient by the rendering provider, or that the service does not meet the criteria for a direct patient encounter. It frequently arises when documentation fails to substantiate the provider's direct physical or synchronous virtual involvement with the patient during the encounter.
Common Causes for CO-112
Denials with code CO-112 typically happen for the following specific reasons:
- Billing for direct face-to-face evaluation and management (E/M) services when the provider only communicated with a caregiver or family member without meeting specific CPT exception criteria.
- Failing to meet CMS 'incident-to' guidelines, such as billing under a physician's NPI when the supervising physician was not physically present in the office suite to oversee the auxiliary staff.
- Inappropriate billing of telehealth or remote services without using the correct modifiers (e.g., 95, GT) or using codes that strictly require physical, face-to-face contact.
- Billing for administrative, care coordination, or portal-based services using codes that represent direct clinical patient care.
How to Prevent CO-112 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify and document the physical presence of the supervising physician within the office suite for all services billed under 'incident-to' guidelines.
- Utilize specific non-face-to-face CPT codes (e.g., caregiver training, chronic care management) when services are rendered without the patient present.
- Apply appropriate telehealth modifiers and place-of-service codes to accurately represent virtual, synchronous direct care.
- Conduct regular audits of electronic health record (EHR) templates to ensure they prompt providers to explicitly document direct patient interaction and contact time.

Denial Code: CO-112 - Service not furnished directly to the patient
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CO-112: "Service not furnished directly to the patient".
We are appealing the denial of this claim (CO-112) as the medical record clearly demonstrates the service was furnished directly to the patient in accordance with CMS and AMA CPT guidelines. The attached documentation for the date of service confirms that the rendering provider established direct, active contact with the patient (either through face-to-face clinical interaction or validated synchronous telehealth protocol). Furthermore, all billing requirements, including direct provider involvement and appropriate supervision guidelines where applicable, have been met and documented. We respectfully request that you review the enclosed clinical chart notes and reverse this denial to allow for prompt payment of the service.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
