       Date of Service:    2026-03-16

       Diagnosis Code:     ICD-10 N39.99

Dear Synthetic Humana Appeals Department,

On behalf of [Hospital/Facility Name], we are writing to formally appeal the denial issued on 2026-05-15 for Claim Number TEST-CLAIM-00078, associated with services rendered on 2026-03-16. The claim was denied under reason code CO-252, indicating that an attachment or other documentation is required to adjudicate the claim. We respectfully contest this denial and submit herewith the documentation necessary to satisfy the payer's request and facilitate prompt adjudication.

I. BACKGROUND AND BASIS FOR APPEAL

On 2026-03-16, our facility provided medically necessary urological services to the above-referenced patient, including procedures reported under CPT codes 50668 (nephrectomy procedure) and 54500 (urological procedure), for the diagnosis of other specified urinary disorder (ICD-10: N39.99). A total amount of $1,136.87 was billed, of which $758.04 remains denied. The denial issued on 2026-05-15 does not reflect a determination that the services were non-covered or medically unnecessary; rather, it is an administrative suspension pending receipt of supporting clinical documentation.

II. GROUNDS FOR OVERTURN

The CO-252 denial code represents an administrative hold, not a substantive adverse determination on coverage or medical necessity. Accordingly, the denial should be overturned and the claim reprocessed upon review of the enclosed documentation, which directly addresses the stated deficiency. Specifically:

  1. Medical Necessity and Clinical Indication Are Fully Documented. The enclosed letter of medical necessity, pre-operative clinical notes, and patient history collectively establish the clinical basis and indication for the nephrectomy and urological procedures performed. The diagnosed urinary disorder (N39.99) and the clinical course leading to surgical intervention are thoroughly documented therein.

  2. Operative and Pathology Records Confirm Services as Billed. The enclosed operative report provides a complete account of the procedures performed on 2026-03-16, confirming the services corresponding to CPT codes 50668 and 54500. The enclosed pathology report further corroborates the clinical findings identified during and arising from the surgical procedure.

  3. Diagnostic Studies Support the Diagnosis and Treatment Plan. The enclosed imaging studies (which may include ultrasound, CT, and/or MRI results, as applicable) and laboratory results substantiate the diagnosis of the urinary disorder and confirm that surgical intervention was the appropriate and indicated course of treatment.

  4. The Denial Is Purely Administrative and Curable. Per Synthetic Humana's documentation submission requirement policy, a CO-252 denial indicates the claim was suspended pending receipt of supporting attachments rather than denied on substantive grounds. Submission of the requested documentation within the applicable appeal window — well in advance of the 2026-07-14 deadline — constitutes a straightforward and complete remedy to the stated deficiency.

III. SUPPORTING DOCUMENTATION ENCLOSED

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

  1. Operative report (2026-03-16)
  2. Pathology report
  3. Pre-operative clinical notes and patient history
  4. Letter of medical necessity documenting indication for CPT 50668 and CPT 54500
  5. Imaging studies (ultrasound, CT, and/or MRI) supporting the diagnosis
  6. Laboratory results
  7. Discharge summary
  8. This appeal letter

IV. REQUESTED REMEDY

We respectfully request that Synthetic Humana:

  (a) Accept and review the enclosed documentation in response to the CO-252 denial;
  (b) Reprocess Claim Number TEST-CLAIM-00078 in its entirety; and
  (c) Issue payment of the denied amount of $758.04 in accordance with the applicable contract terms and benefits.

We believe the enclosed documentation fully satisfies the payer's stated documentation requirement and that no substantive basis for denial exists. Should additional information be needed to complete adjudication, please contact our Appeals Department at [Contact Name, Phone, and Address] at your earliest convenience.

Thank you for your prompt attention to this matter. We trust that upon review of the enclosed records, this claim will be approved and payment issued accordingly.

Respectfully submitted,
