    ICD-10-CM Code For Follicular Cysts Of Skin And Subcutaneous Tissue: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group L72 includes benign follicular cysts of the skin and subcutaneous tissue, such as epidermal inclusion cysts and pilar cysts, which arise from hair follicle structures. These ICD-10-CM diagnosis codes are used to document clinical encounters for patients with localized cystic lesions of appendages, capturing details like lesion type, location, and complications when present. Accurate coding within the ICD-10-CM L72 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM L72: Follicular Cysts Of Skin And Subcutaneous Tissue Overview

    The ICD-10-CM L72 group represents benign cystic lesions arising from hair follicles and related structures of the skin and subcutaneous tissue. These diagnoses target dermatologic appendage disorders involving localized cyst formation, such as epidermal inclusion cysts and pilar cysts. Accurate coding supports appropriate clinical documentation and reimbursement by clearly distinguishing these follicular cysts from infectious, neoplastic, or inflammatory skin conditions.

    When to Use

    Use a code from this group when a patient is diagnosed with a follicular cyst of the skin or subcutaneous tissue documented by clinical examination or histopathology. Select the specific code that reflects the cyst type, anatomical location, and any documented complications to ensure precise clinical and billing records.

    Typical Clinical Scenarios

    • An adult presents to dermatology with a single, tender, fluctuant subcutaneous nodule on the scalp that has been intermittently painful for weeks and intermittently drains a small amount of purulent material. Examination suggests an inflamed follicular cyst (epidermal inclusion cyst) with surrounding erythema but no systemic signs; the patient requests excision. A diagnosis from this group is assigned to characterize a localized inflamed follicular cyst requiring procedural management. Typical codes: L72.0, L72.9.
    • A young adult with multiple recurrent, non-inflamed cyst-like lesions along the hair-bearing chest and back reports chronic cosmetic concern and occasional mild discomfort; conservative measures have failed and the lesions have been present for years. This chronic presentation of numerous persistent follicular-derived cysts is coded from this group to document a long-standing disorder of skin appendages and to guide long-term management. Typical codes: L72.11, L72.12.
    • An elderly patient is admitted from a nursing facility with a large, erythematous, fluctuant mass in the axilla associated with surrounding cellulitis and systemic fever; incision and drainage are performed. Because the source is a ruptured or infected follicular cyst with secondary infection, a code from this group is used to indicate the primary follicular cyst as the origin of the complication alongside infection codes for sepsis or cellulitis as applicable. Typical codes: L72.2, L72.3.
