    ICD-10-CM Code For Atrophic Disorders Of Skin: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group L90 includes atrophic skin disorders such as localized and generalized cutaneous atrophy, idiopathic guttate atrophy, and other conditions characterized by thinning or loss of dermal tissue and scarring. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving loss of skin substance, changes in skin architecture, and related sequelae that affect management decisions and monitoring. Accurate coding within the ICD-10-CM L90 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM L90: Atrophic Disorders Of Skin Overview

    The diagnoses in this group represent skin conditions characterized by thinning, loss of tissue, or localized loss of dermal or subcutaneous structures affecting the integumentary system. These codes capture disorders such as localized and generalized cutaneous atrophy and scarring conditions that alter skin integrity. Accurate coding is important for complete clinical documentation and supports correct reimbursement by reflecting disease severity and treatment needs.

    When to Use

    Use a code from this group when clinical documentation identifies atrophic changes of the skin, such as localized thinning, depressed scars, or generalized cutaneous atrophy that require monitoring or management. Select the most specific code that reflects the documented anatomical distribution and etiology when available to support accurate clinical records and billing.

    Typical Clinical Scenarios

    • An elderly patient presents to dermatology with slowly progressive, shiny, taut skin and visible scarring of the forearms and lower legs after years of chronic dermal fibrosis; they report restricted joint movement and cosmetic concern. The clinician documents localized sclerotic plaques with atrophy of the dermis and subcutaneous tissue and assigns a code for localized scleroderma (morphea) to capture the chronic, indolent atrophic process. Typical codes: L90.0, L90.1
    • A middle-aged patient with a history of long-standing discoid lupus erythematosus follows up for worsening scarring and hypopigmented, atrophic plaques on the scalp with associated permanent hair loss. The visit is for evaluation of disease-related skin atrophy and scarring alopecia; the provider assigns an atrophic skin disorder code to reflect cutaneous scarring and tissue loss secondary to the autoimmune dermatosis. Typical codes: L90.5, L90.2
    • A young adult arrives at urgent care after an infection and cellulitis have resolved but now has focal loss of subcutaneous fat and depression of the skin at the prior injection site, causing functional and cosmetic concerns. The clinician documents postinflammatory localized atrophy and selects an atrophic skin disorder code to describe the acquired focal tissue loss as a complication of prior inflammation/trauma. Typical codes: L90.3, L90.8
