Quick Explanation
Denial code CCM28 indicates that the payer has determined the billed nutritional assessment was not comprehensive enough to meet their clinical documentation requirements. This typically means the medical record lacked essential assessment components, such as detailed dietary histories, anthropometric measurements, or a fully defined nutritional care plan.
Common Causes for CCM28
Denials with code CCM28 typically happen for the following specific reasons:
- Omission of mandatory clinical elements such as height, weight, body mass index (BMI), or relevant laboratory values in the patient record.
- Failure to document a highly individualized nutritional plan of care with specific, measurable goals and intervention strategies.
- Submitting claims for a comprehensive medical nutrition assessment (e.g., CPT 97802) when the documentation only supports a basic nutritional screening or brief progress check.
- Absence of a formal, documented referral from a treating physician establishing the medical necessity for a comprehensive nutritional evaluation.
How to Prevent CCM28 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Utilize structured Electronic Health Record (EHR) templates specifically designed for Registered Dietitians to ensure all CMS-required elements of a comprehensive assessment are completed.
- Conduct regular staff education on the clinical documentation standards outlined in CMS National Coverage Determination (NCD) 180.1 for Medical Nutrition Therapy.
- Establish a pre-billing review process to verify that every initial nutritional assessment claim contains documented anthropometrics, dietary history, and a clear treatment plan.
- Verify that a valid, signed physician referral detailing the patient's qualifying medical condition (e.g., diabetes or non-dialysis renal disease) is scanned into the chart prior to billing.

Denial Code: CCM28 - Nutritional assessment not comprehensive
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CCM28: "Nutritional assessment not comprehensive".
We are formally appealing the denial of the comprehensive nutritional assessment billed under procedure code 97802 for the patient. In accordance with CMS National Coverage Determination (NCD) 180.1 and American Medical Association (AMA) CPT guidelines, the attached medical documentation for the encounter on the specified date of service demonstrates a fully comprehensive assessment. The record contains all requisite elements, including detailed anthropometric measurements, biochemical data review, clinical and dietary history, and a customized nutritional plan of care with established therapeutic goals. Because the clinical documentation completely satisfies the requirements for a comprehensive medical nutrition therapy assessment, we request that this denial be overturned and the claim be reprocessed for immediate 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]
