Patients with an existing diagnosis of squamous cell carcinoma of the esophagus

M1192 (“Patients with an existing diagnosis of squamous cell carcinoma of the esophagus”) is a code used to bill for equipment, supplies, drugs, or non-physician services in the HCPCS Level II code set. Whether it is billed — and whether a payer covers it — depends on the clinical setting, documentation, and plan rules.
