Nationally, coverage and reimbursement for small-volume oral lubricants matter because they affect access for patients with dry mouth from medications, radiation therapy, Sjögren’s syndrome, or other causes. Payment policies influence whether patients receive these products through pharmacy benefits, durable medical equipment channels, or medical benefit carve-outs.

Readers will find a concise explanation of what the code represents, typical sites of service, and what to expect in payer coverage frameworks. The publication summarizes benchmarks for usage and reimbursement where available, highlights common billing and coding considerations tied to dispensing small-volume oral lubricants, and outlines the clinical context in which A9155 is commonly used.

Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient oncology clinic with persistent xerostomia following head and neck radiation therapy. The patient reports dry mouth symptoms that interfere with oral intake, dentition maintenance, and sleep. The clinician assesses oral mucosa, reviews radiation dose history, and documents symptomatic dry mouth despite saliva substitutes and topical measures. The clinician orders dispensation of A9155 (Artificial saliva, 30 ml) to be provided by the clinic or dispensed via a contracted durable medical supply vendor. The clinical workflow includes medication counseling on frequency of use, documentation of medical necessity tied to the patient’s diagnosis (for example, radiation-induced xerostomia or Sjögren’s syndrome), recording the quantity dispensed, verifying insurance benefits and coverage criteria, and attaching the appropriate diagnosis code(s) to support coverage. If coverage requires a prescription, a dated and signed order is placed in the medical record. Billing is submitted to the patient’s payor using HCPCS code A9155, with any applicable modifier to explain circumstances (for example, reduced services or an unusual procedural service). Typical sites of service are outpatient clinics, oncology infusion centers, radiation oncology clinics, dental specialty clinics, and home health settings where topical oral agents are provided as part of supportive care.
