Other acute skin changes due to ultraviolet radiation (L56)

Browse all the diagnosis codes used for other acute skin changes due to ultraviolet radiation (l56). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Hydroa Vacciniforme - A vesicular and bullous eruption having a tendency to recur in summer during childhood and commonly appearing on sun-exposed skin. The lesions are surrounded by an erythematous zone and resemble a vaccination. (From Dorland, 27th ed)

Keratinocytes - Epidermal cells which synthesize keratin and undergo characteristic changes as they move upward from the basal layers of the epidermis to the cornified (horny) layer of the skin. Successive stages of differentiation of the keratinocytes forming the epidermal layers are basal cell, spinous or prickle cell, and the granular cell.

Porokeratosis - A heritable disorder of faulty keratinization characterized by the proliferation of abnormal clones of KERATINOCYTES and lesions showing varying atrophic patches surrounded by an elevated, keratotic border. These keratotic lesions can progress to overt cutaneous neoplasm. Several clinical variants are recognized, including porokeratosis of Mibelli, linear porokeratosis, disseminated superficial actinic porokeratosis, palmoplantar porokeratosis, and punctate porokeratosis.

Rosacea - A cutaneous disorder primarily of convexities of the central part of the FACE, such as FOREHEAD; CHEEK; NOSE; and CHIN. It is characterized by FLUSHING; ERYTHEMA; EDEMA; RHINOPHYMA; papules; and ocular symptoms. It may occur at any age but typically after age 30. There are various subtypes of rosacea: erythematotelangiectatic, papulopustular, phymatous, and ocular (National Rosacea Society's Expert Committee on the Classification and Staging of Rosacea, J Am Acad Dermatol 2002; 46:584-7).

Rosaceae - The rose plant family in the order ROSALES and class Magnoliopsida. They are generally woody plants. A number of the species of this family contain cyanogenic compounds.

Rosales - An order of the class MAGNOLIOPSIDA. Its members include some of the most known ornamental and edible plants of temperate zones including roses, apples, cherries, and peaches.

Skin Pigmentation - Coloration of the skin.

Sunbathing - Exposing oneself to SUNLIGHT or ULTRAVIOLET RAYS.

Suntan - An induced skin pigment (MELANIN) darkening after exposure to SUNLIGHT or ULTRAVIOLET RAYS. The degree of tanning depends on the intensity and duration of UV exposure, and genetic factors.

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
