    ICD-10-CM Code For Other Nonscarring Hair Loss: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group L65 includes nonscarring alopecias such as telogen effluvium, anagen effluvium, and other diffuse or localized hair shedding disorders that do not permanently destroy hair follicles. These ICD-10-CM diagnosis codes are used to document acute or chronic patterns of hair loss, capture etiologic associations or triggering events, and indicate disease extent and severity. Accurate coding within the ICD-10-CM L65 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM L65: Other Nonscarring Hair Loss Overview

    The ICD-10-CM L65 group covers nonscarring hair loss disorders affecting the scalp and other hair-bearing areas, such as telogen effluvium and anagen effluvium. These conditions involve hair shedding without permanent follicle destruction and can result from systemic, inflammatory, or treatment-related causes. Accurate coding matters for appropriate claim adjudication and to reflect clinical complexity for reimbursement.

    When to Use

    Use a code from this group when a clinician documents nonscarring hair loss as the primary diagnosis, including descriptions of pattern, duration, and suspected precipitating factors. Choose the most specific code available to reflect whether the hair loss is telogen, anagen, or other nonscarring types and to capture associated clinical details.

    Typical Clinical Scenarios

    • A 28-year-old woman presents to dermatology with several months of progressively widening, symmetric thinning of scalp hair without scarring, associated with a history of recent childbirth and perceived increased hair shedding on brushing. The clinician documents a noninflammatory, diffuse pattern of hair loss consistent with a telogen effluvium variant and assigns a nonscarring hair loss code to reflect the acute diffuse shedding related to a physiologic stressor. Typical codes: L65.0
    • A 55-year-old man with gradual, patterned hair thinning over years seeks evaluation for cosmetic concerns; examination shows progressive reduction in hair density in a male-pattern distribution but preservation of follicular ostia and no signs of scarring. The chronic, androgen-related nonscarring alopecia is coded to describe long-standing nonscarring hair loss managed as a chronic dermatologic condition. Typical codes: L65.9
    • A 40-year-old patient undergoing chemotherapy develops rapid, diffuse hair loss during treatment, prompting an oncology clinic visit for discussion of symptoms and supportive care; the hair loss is noncicatricial and temporally related to cytotoxic medication exposure. A nonscarring hair loss code reflecting drug-induced diffuse alopecia is assigned as a treatment-related complication/comorbidity. Typical codes: L65.1, L65.2
