    ICD-10-CM Code For Acanthosis Nigricans: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group L83 includes diagnoses for acanthosis nigricans, covering benign and associated forms characterized by hyperpigmented, velvety skin changes often in body folds and occasionally linked to systemic conditions. These ICD-10-CM diagnosis codes are used to document the presence, distribution, and clinical context of acanthosis nigricans, capturing disease severity and any associated metabolic or neoplastic associations when relevant. Accurate coding within the ICD-10-CM L83 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM L83: Acanthosis Nigricans Overview

    The diagnoses in this group represent acanthosis nigricans, a skin condition characterized by hyperpigmented, velvety plaques often in intertriginous areas and sometimes associated with metabolic or endocrine disorders. They target the integumentary system and may signal underlying insulin resistance, obesity, endocrine disease, or, rarely, malignancy. Accurate coding matters for appropriate clinical documentation and reimbursement because it links dermatologic findings to associated comorbidities and supports claim adjudication.

    When to Use

    Use a code from this group when acanthosis nigricans is clinically documented by the provider and requires classification for diagnosis, monitoring, or billing. Select codes that reflect the underlying association or cause when documented, such as endocrine disorder or drug relationship, to ensure accurate clinical and administrative records.

    Typical Clinical Scenarios

    • A middle-aged patient with obesity and type 2 diabetes presents to primary care reporting slowly progressive darkened, velvety patches in the axillae and neck noticed over months; the clinician documents characteristic velvety hyperpigmented plaques consistent with acanthosis nigricans as a cutaneous marker of insulin resistance, and assigns the diagnosis to capture the dermatologic finding and its association with metabolic disease. Typical codes: L83
    • An adolescent with rapid onset widespread hyperpigmented, thickened plaques involving the groin and posterior neck is evaluated in dermatology after parents report sudden appearance over weeks; because sudden extensive acanthosis nigricans can signal an underlying endocrine disorder, the skin condition is diagnosed and recorded while the patient undergoes endocrine and metabolic workup. Typical codes: L83
    • An adult referred from oncology presents with new, extensive, and rapidly progressive velvety hyperpigmented plaques on the trunk and mucous membranes; given the concern for paraneoplastic acanthosis nigricans associated with an internal malignancy, the dermatologist documents the cutaneous paraneoplastic lesion as part of the cancer evaluation and staging record. Typical codes: L83
