Internal Claim Reference: 6c9dbc55-fcaf-43d1-9038-25721734d94e
Payer: Synthetic Medicaid-TX

Denial Date: 2026-05-30
Denied Amount: $551.10
Appeal Deadline: 2026-06-29

Dear Appeals and Grievances Department,

This letter constitutes a formal appeal on behalf of our facility regarding the denial of the above-referenced claim. We respectfully request that Synthetic Medicaid-TX overturn the denial issued on 2026-05-30 and reprocess the claim for payment of the denied amount of $551.10.

I. DENIAL REASON

The claim was denied under reason code CO-16: "Claim/service lacks information or has submission/billing error(s)." This denial does not constitute a coverage exclusion or a determination that the services rendered were not medically necessary. Rather, it reflects a correctable informational or coding deficiency, which we are addressing through this appeal and the enclosed supporting documentation.

II. BASIS FOR APPEAL

We believe the denial should be overturned for the following reasons:

  • The CO-16 denial is correctable in nature. A CO-16 denial code, by definition, indicates that the claim lacked required information or contained a submission or billing error — it does not reflect a determination that the services are non-covered or clinically inappropriate. Synthetic Medicaid-TX's own claim submission and billing error correction policy recognizes that such deficiencies are remedied through the submission of a corrected claim with clarified documentation, and we are providing that clarification herewith.

  • The apparent CPT-to-diagnosis linkage requires clarification, which we are providing. The claim billed three procedure codes — CPT 81066 (genetic testing), CPT 17989 (destruction of skin lesion), and CPT 51104 (urinary bladder biopsy) — in conjunction with ICD-10 diagnosis code M17.74 (primary osteoarthritis, right knee). We acknowledge that the relationship between these procedure codes and the primary billed diagnosis may not have been self-evident from the claim form alone, and that this apparent mismatch likely triggered the deficiency flag. The enclosed explanation of medical necessity and clarification letter directly address the clinical rationale linking each CPT code to the diagnoses and clinical circumstances present at the time of service on 2026-04-27.

  • Supporting documentation demonstrates medical necessity for each billed procedure. The enclosed itemized superbill and/or operative report, medical record documentation, and procedure-specific explanation of medical necessity collectively establish the clinical basis for CPT codes 81066, 17989, and 51104 as performed on the date of service. These documents provide the diagnosis-to-procedure crosswalk necessary for the claim to be adjudicated as a clean claim.

  • The denial is timely and properly appealed within the payer's appeal window. The denial was issued on 2026-05-30, and this appeal is being submitted in advance of the appeal deadline of 2026-06-29, in full compliance with Synthetic Medicaid-TX's appeals and grievances requirements.

III. ENCLOSED SUPPORTING DOCUMENTATION

In support of this appeal, the following documents are enclosed for the reviewer's consideration:

  1. Corrected claim submission with accurate coding and billing information
  2. Itemized superbill and/or operative report detailing each procedure performed on 2026-04-27
  3. Procedure-specific explanation of medical necessity for CPT codes 81066, 17989, and 51104
  4. Clarification letter addressing the stated submission/billing error(s) and CPT-to-diagnosis linkage
  5. Medical record documentation supporting the billed ICD-10 diagnosis code (M17.74) and the additional clinical conditions present at the time of service
  6. Payer's coding edits report or specific error notification (as received)

IV. REQUESTED REMEDY

We respectfully request that Synthetic Medicaid-TX:

  1. Overturn the CO-16 denial issued on 2026-05-30 for External Claim ID TEST-CLAIM-00005;
  2. Reprocess the claim in full upon review of the enclosed corrected claim and supporting documentation; and
  3. Issue payment of the denied amount of $551.10 in accordance with the applicable fee schedule and plan provisions.

We are committed to resolving this matter in a timely and collaborative manner and welcome any additional information requests from the clinical or claims review team. Please direct any correspondence or requests for additional documentation to the contact information below.

Thank you for your prompt attention to this appeal.
