Denial Code: SLP04 - Voice therapy medical necessity unclear

Dear Appeals Department,

I am writing to appeal the denial of the above-referenced claim, which was denied with code SLP04: "Voice therapy medical necessity unclear".

We are appealing the denial of voice therapy services (CPT code 92507) billed under denial code SLP04. In accordance with CMS Local Coverage Determinations (LCD) for outpatient speech-language pathology and ASHA clinical guidelines, voice therapy is medically necessary when a patient exhibits a documented voice disorder that restricts functional communication. A laryngeal examination was performed by an otolaryngologist prior to the initiation of therapy, confirming an organic/functional pathology. The initial speech-language evaluation established objective baseline deficits utilizing the Voice Handicap Index (VHI) and outlined a rehabilitative plan of care with specific, measurable goals. The subsequent progress notes demonstrate the patient's active, documented improvement under the skilled guidance of an SLP, proving the restorative nature of the therapy. We respectfully request that this denial be reversed and the claim processed for payment.

Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].

We respectfully request that you reprocess this claim for payment.

Sincerely,

[Your Name]
