CPT® Code 96910

Photochemotherapy is a specialized treatment modality that combines the use of light therapy with photosensitizing agents to manage severe skin conditions that respond positively to light exposure. The procedure described by CPT® Code 96910 specifically refers to the Goeckerman treatment, which utilizes a combination of coal tar and ultraviolet B (UVB) light, or alternatively, petrolatum with UVB light. This therapy is particularly effective for conditions such as psoriasis, eczema, vitiligo, and mycosis fungoides, which are known to be responsive to phototherapy. In the context of this treatment, coal tar serves as a topical agent that enhances the skin's response to UVB light, while petrolatum acts as a moisturizing barrier that can also facilitate the effects of UVB exposure. The application of these substances is followed by controlled exposure to UVB light, which is administered in a light booth for a predetermined duration based on the specific skin condition being treated. This structured approach aims to reduce inflammation, promote healing, and improve the overall appearance of the skin affected by these challenging dermatological conditions.
