Billing code 95044: Patch testingMedicare rate & RVUs

Medicare pays $5.01 for 95044 nationally in the office. Local office rates run $4.19–$6.92.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 95044 covers

Patch testing identifies delayed reactions associated with allergic contact dermatitis. Small amounts of suspected allergens, such as nickel, fragrance mixes, preservatives, rubber accelerators, or topical medications, are applied to the skin under patches, commonly on the upper back. Clinics may use prepared panels or appropriately prepared substances from a patient's own products. Patches generally remain in place for about 48 hours before removal and an initial reading; a later reading helps identify delayed reactions. Dermatologists and allergists commonly order and interpret the tests, while nurses or medical assistants apply the patches in the office.

Report one unit for each separate patch test, not for each strip or panel. A panel with 35 separately applied tests supports 35 units; document the substances tested, test count, and readings. Select patch testing for suspected delayed contact reactions rather than immediate allergy assessed by prick testing. CMS assigns no physician work RVUs to 95044; its relative value reflects practice expense and malpractice. CMS treats it as an incident-to service billed only when performed under physician supervision. A separately reported E/M requires a significant, independently documented evaluation beyond routine testing and interpretation; use modifier 25 on the E/M when both services occur on the same date.
