E0691 descriptor and code status

The October 2026 HCPCS Level II file describes E0691 as “Ultraviolet light therapy system, includes bulbs/lamps, timer and eye protection; treatment area 2 square feet or less”. It sits in the E section (durable medical equipment), listed with the other E codes. Although searches often call it the "E0691 CPT code", E0691 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.
