Internal Claim Reference: 265e9ab2-978b-4970-b3f4-2beff6aff813
Payer: Synthetic Humana
Date of Service: February 7, 2026
Denial Date: April 26, 2026
Appeal Deadline: June 25, 2026
Denied Amount: $2,073.72
Diagnosis Code(s): G43.38 (Chronic migraine with aura, not intractable, without status migrainosus)
Procedure Code(s): 49651, 90173, 95717

Dear Synthetic Humana Appeals and Grievances Department,

On behalf of [Provider/Facility Name], we are submitting this formal first-level appeal in response to the denial issued on April 26, 2026, for services rendered on February 7, 2026, under Claim No. TEST-CLAIM-00008. The claim was denied under adjustment reason code CO-50, with the payer determining that the billed services — CPT codes 49651 (laparoscopic hernia repair), 90173 (vaccine administration), and 95717 (allergy/immunology testing) — lacked medical necessity in relation to the documented diagnosis of chronic migraine with aura (ICD-10: G43.38).

We respectfully contest this denial in its entirety and request that Synthetic Humana reprocess and approve payment of the denied amount of $2,073.72. The denial is not supported by the complete clinical record and fails to account for the full scope of the patient's medical condition and treating physician's clinical judgment, as further detailed below.

I. GROUNDS FOR APPEAL

A. The Billed Services Were Medically Necessary and Clinically Appropriate

The CO-50 denial determination was made without adequate consideration of the complete clinical picture. The treating physician has documented the clinical rationale for each procedure billed on the date of service. As reflected in the enclosed physician's letter of medical necessity and supporting clinical documentation, each billed procedure was ordered and performed in response to the patient's individual medical needs, consistent with accepted standards of care. The physician's clinical judgment — informed by the patient's documented history, symptom burden, and treatment course — supports the appropriateness of these services.

Peer-reviewed clinical guidelines from recognized professional societies, enclosed herewith, further substantiate the clinical basis for the procedures performed. Denial of a claim solely on the grounds that procedure codes appear facially unrelated to a single listed diagnosis, without review of the complete clinical record, does not constitute a sufficient basis for a medical necessity determination under the payer's own medical necessity criteria.

B. The Apparent Diagnostic-to-Procedure Relationship Requires Contextual Clinical Review

We acknowledge that, at first review, the combination of diagnosis code G43.38 (chronic migraine with aura) with procedure codes 49651, 90173, and 95717 may appear incongruous. However, this apparent mismatch does not, in and of itself, establish a lack of medical necessity. There are two recognized explanations that the payer's review should have considered prior to issuing a denial:

1. The patient may present with comorbid conditions — beyond the primary listed diagnosis — that independently support each billed procedure. The enclosed clinical documentation and operative report detail the full clinical context, including any comorbid diagnoses that informed the treating physician's decision to proceed with each service.

2. To the extent that any coding clarification is warranted, the enclosed documentation provides the necessary clinical support to resolve any ambiguity. We respectfully request that Synthetic Humana's clinical reviewer evaluate the claim in light of the complete enclosed record rather than on the face of the claim submission alone.

The payer's medical necessity criteria require that coverage determinations be based on whether a service is clinically appropriate for the individual patient's condition — not on a cursory comparison of diagnosis and procedure codes absent clinical context. The enclosed records satisfy that standard.

C. Conservative Treatment History Supports Escalation of Care

The enclosed treatment history and prior conservative therapy records demonstrate that the patient's care followed an appropriate, stepwise clinical course. The procedures performed on February 7, 2026, were not rendered prematurely or in isolation, but rather as part of a longitudinal treatment plan supported by documented clinical progression. This history is directly relevant to the medical necessity determination and was not, to our knowledge, considered in the payer's initial review.

D. Prior Authorization Documentation Supports Payer Awareness of Planned Services

To the extent that prior authorization was sought for any of the billed services, the enclosed prior authorization request and supporting clinical notes reflect that the treating team presented the clinical rationale for these services in advance. Any prior authorization obtained for these services is inconsistent with a subsequent determination that the same services lacked medical necessity.

II. ENCLOSED SUPPORTING DOCUMENTATION

In support of this appeal, the following documents are enclosed:

1. Physician's Letter of Medical Necessity — detailing the clinical rationale for each billed procedure in the context of the patient's diagnosis and overall medical condition
2. Clinical Documentation Supporting Diagnosis G43.38 — office notes and records documenting the patient's chronic migraine with aura and related clinical findings
3. Treatment History and Prior Conservative Therapy Records — demonstrating the longitudinal course of care and clinical basis for escalation
4. Peer-Reviewed Clinical Guidelines — from recognized professional societies (e.g., American Headache Society or equivalent), supporting the clinical appropriateness of the billed procedures
5. Prior Authorization Request and Supporting Clinical Notes — submitted in connection with the planned services
6. Operative Report / Procedure Documentation — confirming the services billed were rendered as described and in accordance with the clinical plan

2. Overturn the CO-50 denial issued on April 26, 2026, for Claim No. TEST-CLAIM-00008; and
3. Reprocess the claim and remit payment of the denied amount of $2,073.72 in accordance with the applicable plan terms and the patient's benefits.
