Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the L44 range.
Keratosis Lichenoides Chronica
A rare skin disorder with brownish-purple, thick scaly papules or small nodules arranged in a linear or reticulate pattern on the trunk and limbs. Many cases are associated with seborrheic dermatitis- or rosacea-like lesions on the face. It is distinguished from lichen planus by the absence of pruritus, a lack of response to a topical or systemic corticosteroid and the presence of focal parakeratosis in histological samples.
Lichen Nitidus
A chronic inflammatory disease characterized by shiny, flat-topped, usually flesh-colored micropapules no larger than the head of a pin. Lesions are localized in the early stages, found chiefly on the lower abdomen, penis, and inner surface of the thighs. Distribution may become generalized as the disease progresses.
Pityriasis Rubra Pilaris
A chronic skin disease characterized by small follicular papules, disseminated reddish-brown scaly patches, and often, palmoplantar hyperkeratosis. The papules are about the size of a pin and topped by a horny plug.
Skin Diseases, Papulosquamous
A group of dermatoses with distinct morphologic features. The primary lesion is most commonly a papule, usually erythematous, with a variable degree of scaling on the surface. Plaques form through the coalescing of primary lesions.
About the L44 Code Range
These skin disorders include pityriasis rubra pilaris, several named lichen conditions, and infantile papular acrodermatitis.
The subdivisions separate the named conditions: L44.0 is pityriasis rubra pilaris. L44.1, L44.2, and L44.3 distinguish lichen nitidus, lichen striatus, and lichen ruber moniliformis. L44.4 is infantile papular acrodermatitis, also called Gianotti-Crosti syndrome. L44.8 and L44.9 distinguish other specified disorders from an unspecified disorder.
