Quick Explanation
Denial code CO 288 occurs when a claim fails to comply with specific billing regulations designated for multi-specialty physician groups or clinics. This typically happens when multiple providers of different specialties under the same Tax Identification Number (TIN) render services to the same patient on the same day, and the payer's system cannot differentiate the distinct nature of each visit.
Common Causes for CO 288
Denials with code CO 288 typically happen for the following specific reasons:
- Providers from different specialties within the same group practice billing E/M codes for the same patient on the same date of service without differentiating modifiers.
- Incorrect or missing taxonomy codes on the claim, causing the payer to misidentify the providers as practicing under the same specialty.
- Submitting claims with identical or overlapping ICD-10 diagnosis codes for distinct specialty evaluations, signaling redundant care to the payer.
- Failure to append Modifier 25 or other appropriate modifiers to show that the multi-specialty services were separate and medically necessary.
How to Prevent CO 288 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify and maintain accurate provider enrollment, ensuring unique NPIs and distinct taxonomy codes are registered with all contracted payers.
- Utilize distinct ICD-10-CM diagnosis codes for each specialist's encounter to clearly illustrate the unique clinical conditions being managed.
- Append appropriate modifiers, such as Modifier 25, when different specialists must evaluate the same patient on the same calendar day.
- Configure claim scrubber edits to flag same-day, same-TIN multi-specialty claims for manual review of documentation and coding prior to submission.

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]
