Denial Code: CO 288 - Multi-specialty denial code

Dear Appeals Department,

I am writing to appeal the denial of the above-referenced claim, which was denied with code CO 288: "Multi-specialty denial code".

In accordance with CMS Medicare Claims Processing Manual Chapter 12, Section 30.6.5, physicians in the same group practice who are in different specialties may be paid for separate E/M services rendered to the same beneficiary on the same day, provided the services are for distinct, medically necessary reasons. In this clinical scenario, the patient was evaluated by Dr. [Insert Provider A Name] ([Insert Specialty A]) for [Insert Condition A] and by Dr. [Insert Provider B Name] ([Insert Specialty B]) for [Insert Condition B]. These represent entirely separate, non-overlapping clinical evaluations performed by distinct specialties that cannot be consolidated. The attached clinical documentation clearly supports the independent medical necessity of both encounters, and we respectfully request that this denial be overturned and the claim processed for payment.

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]
