Re:    Formal Appeal of Claim Denial
       Claim Number:       TEST-CLAIM-00067
       Payer:              Synthetic BCBS-TX
       Date of Service:    December 24, 2025
       Denial Date:        March 10, 2026
       Denial Code:        CO-198 – Precertification/Authorization Exceeded
       Denied Amount:      $4,995.23
       Appeal Deadline:    June 8, 2026

Dear Appeals and Grievances Department:

On behalf of [Facility Name] (hereinafter "the Facility"), we respectfully submit this formal written appeal challenging the denial issued on March 10, 2026, for Claim Number TEST-CLAIM-00067. The claim was denied under remark code CO-198, asserting that the precertification or authorization obtained for the December 24, 2025, services was exceeded. For the reasons set forth below, and as substantiated by the enclosed supporting documentation, the Facility respectfully requests that Synthetic BCBS-TX overturn this denial, reprocess the claim, and issue payment of the full denied amount of $4,995.23.

---

I. BACKGROUND AND BASIS FOR DENIAL

The Facility rendered services on December 24, 2025, including CPT 29442 (arthroscopic joint procedure) and CPT 89730 (tissue/cell analysis), in connection with the member's diagnosis of I10.35. The total billed amount for these services was $5,374.18, of which $4,995.23 was denied. The stated basis for denial is CO-198: the payer's determination that the services performed exceeded the scope, quantity, or other parameters of the precertification on file.

The Facility contests this determination in its entirety. Prior authorization was obtained in advance of the December 24, 2025, services, and the enclosed documentation demonstrates that the procedures performed either fell squarely within the authorized scope and date range, or constituted medically necessary modifications to authorized care that should not give rise to a blanket denial of payment.

---

II. GROUNDS FOR APPEAL

A. The Authorized Procedures Were Performed Within the Valid Precertification Period

As reflected in the enclosed prior authorization approval letter and precertification documentation, authorization was secured prior to the date of service. The Facility's itemized billing statement confirms that CPT 29442 and CPT 89730 were rendered on December 24, 2025 — a date that falls within the authorized service date range. The denial on grounds that authorization was "exceeded" is therefore not supported by the record, and the Facility respectfully submits that the payer's determination was issued in error.

B. The Performed Procedures Are Consistent With the Authorized Scope

Both CPT 29442 (arthroscopic joint procedure) and CPT 89730 (tissue/cell analysis) are reflected in or are consistent with the precertification documentation on file. The enclosed operative report/procedure note for CPT 29442 and the enclosed laboratory or pathology report supporting CPT 89730 confirm the clinical basis for each service and demonstrate alignment with the authorized treatment plan. There is no basis for the payer's conclusion that these services surpassed the granted authorization.

C. Any Variance From the Original Authorization Was Medically Necessary and Should Be Recognized by the Payer

In the event that Synthetic BCBS-TX maintains that one or both procedures deviated from the precise parameters of the original precertification, the Facility submits that such deviation, if any, was the result of medically necessary clinical judgment exercised at the point of care. The enclosed letter of medical necessity from the treating physician documents the clinical rationale for the services as delivered on December 24, 2025. Payer policy governing prior authorization scope and quantity limits should not be applied in a manner that results in the wholesale denial of medically necessary care where authorization was obtained in good faith and the services rendered were clinically required.

D. A Denial of $4,995.23 on a Claim With a Valid Authorization Is Disproportionate and Inconsistent With Payer Policy

The Facility recognizes that Synthetic BCBS-TX maintains a prior authorization scope and quantity limit requirement under its applicable coverage policies. However, those policies contemplate a good-faith review of whether services rendered are consistent with granted precertification — not an automatic, blanket denial of nearly $5,000 in services performed on a date for which authorization was obtained. The Facility respectfully asserts that a full denial under CO-198 is not warranted under these facts and urges the payer to conduct a thorough review of the enclosed documentation before affirming the denial.

1. Prior authorization approval letter
2. Precertification documentation with authorized amount and service date range
3. Operative report/procedure note for CPT 29442 (arthroscopic procedure)

5. Letter of medical necessity from the treating physician
6. Itemized billing statement confirming date of service alignment with the authorization period

IV. REQUESTED REMEDY

Based on the foregoing, the Facility respectfully requests that Synthetic BCBS-TX:

1. Overturn the CO-198 denial issued on March 10, 2026, for Claim Number TEST-CLAIM-00067;
2. Reprocess the claim in full in light of the enclosed authorization and clinical documentation; and
3. Issue payment of the denied amount of $4,995.23 in accordance with the applicable contracted rate and benefit provisions.

Should the payer require additional clinical documentation or wish to arrange a peer-to-peer review with the treating physician, the Facility welcomes that opportunity and requests that any such outreach be directed to [Facility Appeals Contact Name and Contact Information].

This appeal is submitted on a timely basis ahead of the June 8, 2026, appeal deadline. The Facility reserves all rights to further levels of appeal, external review, and any other remedies available under applicable law and the parties' agreement, should this appeal not be resolved in the Facility's favor.
