Date of Service: January 19, 2026
Denial Date: April 3, 2026
Procedure Code(s): CPT 56129

Denied Amount: $1,291.15
Appeal Deadline: July 2, 2026

Dear Appeals and Grievances Review Committee:

This letter constitutes a formal written appeal on behalf of the treating facility regarding the denial of Claim TEST-CLAIM-00081, issued by Synthetic BCBS-TX on April 3, 2026. The claim was denied under reason code CO-197 (Precertification/authorization/notification absent) for services rendered on January 19, 2026, resulting in a denied amount of $1,291.15. We respectfully request that this denial be overturned and that the claim be reprocessed for payment of the full denied amount.

I. GROUNDS FOR APPEAL

We contest this denial on the following bases:

1. Prior Authorization Was Obtained Prior to or Concurrent with Service Delivery

Contrary to the assertion in the CO-197 denial, a prior authorization request was submitted to Synthetic BCBS-TX in connection with the services rendered on January 19, 2026. Enclosed with this appeal are the prior authorization request and the prior authorization approval letter issued by the payer, which together demonstrate that precertification was in fact obtained. The payer's own internal records should reflect the existence of this authorization. A denial citing the absence of precertification, when such authorization exists on record, constitutes an administrative error that warrants immediate correction.

We further note that the denial was not issued until April 3, 2026 — approximately two and one-half months after the date of service. This delay raises the concern that the payer may not have cross-referenced its authorization records prior to issuing the denial. We respectfully urge the appeals reviewer to conduct a thorough search of the payer's authorization database prior to rendering a decision on this appeal.

2. The Payer's Authorization Requirement May Not Have Applied to This Procedure Under the Member's Plan

In the alternative, we call the appeals reviewer's attention to the procedure-diagnosis pairing at issue: CPT 56129 (vulvectomy) was billed in conjunction with diagnosis code K21.59 (gastroesophageal reflux disease). We request that the reviewing body scrutinize whether precertification was actually required under the member's specific benefit plan for CPT 56129 in the context of this clinical presentation and diagnosis. If the member's plan documents do not mandate prior authorization for this procedure under the applicable clinical circumstances, the CO-197 denial is inapplicable and the claim should be paid as submitted.

II. SUPPORTING DOCUMENTATION

The following documents are enclosed in support of this appeal:

- The prior authorization request submitted in connection with the January 19, 2026 date of service
- The prior authorization approval letter from the payer
- The operative report for CPT 56129 performed on January 19, 2026
- Clinical documentation supporting the medical necessity of the procedure
- Proof of timely submission of the authorization request (including timestamps, fax confirmation, or portal submission evidence, as applicable)
- Communication logs reflecting authorization inquiries and any payer responses

These documents collectively establish that precertification was sought and obtained, and that the services were medically necessary and clinically appropriate. We respectfully submit that the enclosed letter of medical necessity and the operative report further corroborate the clinical rationale for the procedure performed.

III. REQUESTED REMEDY

For the reasons set forth above, we respectfully request that Synthetic BCBS-TX:

1. Overturn the CO-197 denial issued on April 3, 2026, with respect to Claim TEST-CLAIM-00081;
2. Reprocess the claim in full; and
3. Issue payment of the denied amount of $1,291.15 in accordance with the member's applicable benefit plan and the contracted rate between the facility and Synthetic BCBS-TX.

If additional information is required to resolve this appeal, please contact the facility's billing and authorization department at the address or phone number on file. We trust that upon review of the enclosed documentation, the merit of this appeal will be evident, and we look forward to a prompt and favorable determination.

This appeal is being submitted within the applicable appeal deadline of July 2, 2026.

Respectfully submitted,
