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.

- 95028Allergy skin testing
- Both can assess delayed reactions, but 95028 introduces the test substance intradermally. 95044 applies it to the skin surface.
95044 billing questions
How many units of 95044 are reported?
Report one unit per separate patch test, not per strip or panel. Document each substance and test site so the unit count can be verified.
Are patch removal and delayed readings billed separately?
No. Removal and readings are part of the patch testing service; routine interpretation of the results does not by itself support a separate E/M.
Can an E/M be billed on the day patches are applied?
Yes, if a significant, separately identifiable evaluation is documented beyond the work associated with testing. Append modifier 25 to the E/M reported on the same date.
Why does 95044 have no physician work RVUs?
CMS values 95044 through practice expense and malpractice RVUs and treats it as an incident-to service billed only when performed under physician supervision. A separate E/M is reported only when its own documentation and service requirements are met.
When should photo patch testing be reported instead?
When patches are used with controlled light exposure to investigate photoallergic contact dermatitis, report the photo patch tests with 95052 rather than 95044.
