Pityriasis versicolor

This code represents a superficial fungal infection of the skin, also known as tinea versicolor, caused by the Malassezia yeast. It typically presents as discolored patches on the trunk, neck, and arms, which can be hypopigmented or hyperpigmented, and may be mildly scaly or itchy. The condition is generally benign and primarily a cosmetic concern.

Use this code when documentation indicates a diagnosis of pityriasis versicolor, tinea versicolor, or dermatomycosis furfuracea. This diagnosis is often made clinically based on the characteristic appearance of the lesions, sometimes confirmed with a KOH prep showing hyphae and spores.

• Do not confuse with other dermatophyte infections; this is a superficial yeast infection.
• Ensure documentation specifies "versicolor" to differentiate from other forms of pityriasis.
• No laterality is specified for this code, as it typically affects multiple areas of the body.
