Respiratory Question for the Week of August 20, 2018


How is oxygen billed to Medicare?


There is no CPT® code for oxygen. Do not bill for oxygen using the unlisted CPT code 94799. Bill it with the revenue code 0271, designating it as a supply. It must be billed in “measurable” units, such as per liter, per hour, per quarter hour, per minute. There must be a written order for the oxygen. “PRN Oxygen” is not satisfactory for Medicare reimbursement.
