    ICD-10-CM Code For Androgenic Alopecia: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group L64 includes diagnoses for pattern hair loss associated with androgenic alopecia, covering male and female pattern baldness and related hereditary or hormonal scalp hair thinning conditions. These ICD-10-CM diagnosis codes are used to document clinical encounters for progressive scalp hair loss, capturing disease distribution, severity, and whether the presentation is male or female pattern. Accurate coding within the ICD-10-CM L64 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    Typical Clinical Scenarios

    • A middle-aged man presents to dermatology with gradual, progressive thinning of the frontal hairline and vertex scalp over several years; he reports a family history of similar hair loss and no associated scalp scaling or inflammation. Examination shows characteristic patterned hair miniaturization consistent with male-pattern hair loss, and a diagnosis from this group is assigned for chronic androgen-related alopecia. Typical codes: L64.0
    • A postmenopausal woman reports diffuse thinning along the crown and widening of the central part over months, concerned about cosmetic hair loss; hormonal evaluation is unrevealing and there are no signs of scarring or other dermatologic disease. Clinical assessment indicates female-pattern (androgenic) alopecia as the primary chronic hair disorder, so a code from this group is used to document the condition and ongoing management. Typical codes: L64.8
    • An outpatient with long-standing androgenic hair loss presents for preoperative evaluation before hair transplant surgery and requests documentation of the diagnosis for surgical planning and insurance review; prior topical and systemic therapies are noted with persistent patterned hair thinning. The encounter is coded to reflect the underlying androgenic alopecia as a comorbidity influencing procedural planning. Typical codes: L64.9
