Re: Formal Appeal of Medical Necessity Denial
Claim Number: TEST-CLAIM-00048
Internal Claim ID: 057297cc-c953-4551-9cfa-794cb623ce29
Date of Service: January 31, 2026
Denial Date: April 20, 2026
Denied Amount: $1,615.37
Procedure Codes: CPT 54548, CPT 76550

Dear Synthetic UHC Appeals and Grievances Department,

This letter constitutes a formal, first-level appeal on behalf of our facility regarding the denial of the above-referenced claim. Synthetic UHC issued a denial on April 20, 2026 under remark code CO-50, asserting that the services rendered on January 31, 2026 — specifically CPT 54548 and CPT 76550 — were not deemed medically necessary. Our facility respectfully disagrees with this determination and requests that the denial be overturned and the denied amount of $1,615.37 be reprocessed for payment.

I. BACKGROUND AND BASIS FOR DENIAL

The claim in question (TEST-CLAIM-00048) was submitted for services provided on January 31, 2026, with a total billed amount of $4,630.34. Synthetic UHC approved a portion of the claim but denied $1,615.37 — the amount attributable to CPT 54548 and CPT 76550 — on the stated grounds of medical necessity (CO-50). The patient's documented diagnoses include M17.36 (bilateral primary osteoarthritis, knee) and K21.75 (gastro-esophageal reflux disease with esophageal ulcer), both of which directly support the clinical rationale for the procedures performed.

II. GROUNDS FOR APPEAL

Our facility contends that the CO-50 denial constitutes a blanket medical necessity determination that is inconsistent with the clinical record and does not account for the totality of documented evidence. The following points support overturning the denial:

1. Documented Diagnoses Support Medical Necessity
The treating diagnoses of M17.36 (knee osteoarthritis) and K21.75 (GERD with esophageal ulcer) are well-established, clinically recognized conditions that require active management. The procedures billed — CPT 54548 and CPT 76550 — are clinically appropriate responses to the documented conditions and align with established standards of care. A blanket determination of non-medical necessity, without reference to the specific clinical circumstances, is insufficient to sustain this denial.

2. Treating Physician's Letter of Medical Necessity
Enclosed is the letter of medical necessity from the treating physician, which sets forth in detail the clinical rationale for the procedures performed on January 31, 2026. The treating physician's clinical judgment, grounded in direct examination and review of the patient's history, affirms that both CPT 54548 and CPT 76550 were required interventions given the patient's documented conditions. Payer medical necessity criteria recognize the treating physician's assessment as a central component of any necessity determination.

3. Prior Conservative Treatment and Clinical Documentation
The enclosed clinical documentation demonstrates that conservative treatment modalities were attempted and documented prior to the procedures billed under this claim. This progression of care is consistent with evidence-based practice and satisfies the payer's medical necessity criteria, which typically require that less invasive treatments be considered before advancing to more intensive interventions.

4. Peer-Reviewed Clinical Guidelines and Procedure Documentation
The enclosed peer-reviewed clinical guidelines for CPT 54548 and CPT 76550 confirm that these procedures are recognized as medically appropriate for the diagnoses at issue. Additionally, the enclosed operative/procedure notes from January 31, 2026, and the imaging and diagnostic reports (including ultrasound documentation pertaining to CPT 76550) provide objective, contemporaneous evidence of medical necessity that directly contradicts the payer's CO-50 finding.

III. POLICY ANALYSIS

Synthetic UHC's medical necessity criteria require that covered services be consistent with the diagnosis, in accordance with accepted standards of medical practice, and not primarily for the convenience of the patient or provider. As demonstrated by the enclosed documentation, the services rendered on January 31, 2026 satisfy each of these criteria. The payer's CO-50 denial does not identify any specific clinical criterion that was not met, nor does it provide a clinical rationale sufficient to override the documented judgment of the treating physician. Our facility respectfully submits that the denial is not supported by the applicable medical necessity criteria when applied to the specific facts of this claim.

IV. REMEDY REQUESTED

Based on the foregoing, our facility respectfully requests that Synthetic UHC:

1. Overturn the CO-50 medical necessity denial for CPT 54548 and CPT 76550 on claim TEST-CLAIM-00048;
2. Reprocess the claim in full; and
3. Issue payment of the denied amount of $1,615.37 in accordance with the applicable agreement and benefit provisions.

This appeal is being submitted in advance of the appeal deadline of July 19, 2026. Should Synthetic UHC require any additional documentation or wish to arrange a peer-to-peer review between its medical reviewer and the treating physician, please contact our facility's billing and appeals department at the information provided below.

V. ENCLOSED DOCUMENTATION

- Letter of medical necessity from treating physician
