Allergy testing
About 95052: Photopatch allergy testing
Photopatch testing evaluates suspected light-dependent contact allergy by comparing skin reactions to applied substances with and without light exposure.
Photopatch testing evaluates suspected photoallergic contact dermatitis, such as a reaction linked to a topical medication, sunscreen, or fragrance after sun exposure. The clinician applies suspected substances to the skin under patches, then exposes one test area to light while keeping a comparison area shielded. Subsequent skin responses are interpreted to determine whether the reaction depends on light. Dermatologists and allergists commonly perform this testing in an office setting.
Report 95052 for the photopatch procedure, which includes application and interpretation. Documentation should identify the clinical concern, substances tested, test locations, exposure and comparison conditions, and observed reactions. CMS assigns 0 work RVUs, 0.17 practice-expense RVUs, and 0.01 malpractice RVUs. This is an incident-to service and is billed only when performed under physician supervision.

95052 billing questions
How does 95052 differ from 95044?
95052 evaluates whether light contributes to a skin reaction to an applied substance. 95044 is used for conventional patch or application testing without the photopatch comparison.
How does photopatch testing differ from 95056?
Photopatch testing assesses reactions to applied substances with and without light exposure. 95056 evaluates the skin's response to light itself, without testing an applied contact allergen.
Does 95052 include application and interpretation?
Yes. The photopatch service includes applying the test materials and interpreting the reactions; document the testing and findings in the record.
Can staff perform the testing for a physician claim?
CMS identifies 95052 as an incident-to service, so it is billed only when performed under physician supervision.
What documentation supports reporting 95052?
Document the suspected light-dependent contact reaction, the substances and sites tested, which area received light exposure, the comparison conditions, and the interpreted skin findings.
