Other specified hypertrophic and atrophic conditions of skin

This code represents various non-inflammatory, non-neoplastic changes in skin tissue characterized by either overgrowth (hypertrophy) or wasting away (atrophy) that are not classified elsewhere. These conditions involve alterations in the skin's structure, leading to thickening or thinning of the epidermis, dermis, or subcutaneous tissue.

Use this code for documented hypertrophic or atrophic skin conditions that are specifically identified by the provider but do not have a more precise ICD-9-CM code. Examples include localized lipodystrophy, anetoderma, or other specified non-inflammatory skin changes. Documentation should clearly state the specific condition and its hypertrophic or atrophic nature.

• Ensure the physician's documentation specifies the exact hypertrophic or atrophic condition; avoid using this code for vague or unspecified diagnoses.
• Differentiate from inflammatory skin conditions (e.g., dermatitis) or neoplastic processes, which have their own distinct codes.
• Review for any underlying systemic conditions that may be causing the skin changes, as these may need to be coded first as the primary diagnosis.
