Question: What code applies to a face-to-face evaluation for a power wheelchair? Maryland Subscriber Answer: The best code choice is G0372 (Physician service required to establish and document the need for a power mobility device [use in addition to primary evaluation and management code]). Note that the face-to-face requirement is met when the physician evaluates the patient within the specified timeframe. Also note that you may bill this in addition to an E/M code that otherwise describes the encounter.
