G0383 descriptor and code status

The October 2026 HCPCS Level II file describes G0383 as “Level 4 hospital emergency department visit provided in a type b emergency department; (the ed must meet at least one of the following requirements: (1) it is licensed by the state in which it is located under applicable state law as an emergency room or emergency department; (2) it is held out to the public (by name, posted signs, advertising, or other means) as a place that provides care for emergency medical conditions on an urgent basis without requiring a previously scheduled appointment; or (3) during the calendar year immediately preceding the calendar year in which a determination under 42 cfr 489.24 is being made, based on a representative sample of patient visits that occurred during that calendar year, it provides at least one-third of all of its outpatient visits for the treatment of emergency medical conditions on an urgent basis without requiring a previously scheduled appointment)”. It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0383 CPT code", G0383 is a HCPCS Level II code maintained by CMS, not an AMA CPT code; both go in the same procedure-code field on the claim.
