ICD-10 Code L92 – Granulomatous Disorders of Skin and Subcutaneous Tissue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L92 – Granulomatous disorders of skin and subcutaneous tissue
What it is
L92 is the code category for granulomatous disorders affecting the skin and subcutaneous tissue. Use it when the record describes a granulomatous inflammatory condition of these tissues and no more specific diagnosis is documented.
Clinical signs
Clinical features vary; refer to documentation. Findings may include firm skin or subcutaneous nodules, plaques, or other granulomatous lesions confirmed by clinical assessment, biopsy, or pathology.
When to use this code
Use L92 when the provider documents a granulomatous disorder of the skin or subcutaneous tissue without naming a more specific condition. It may also fit when pathology supports a granulomatous process and the chart does not identify a different coded diagnosis.
Check the note for anatomic site and exact wording. If the record specifies a distinct granulomatous disease with a more precise code, you should code that diagnosis instead.
Do not use for
Do not use L92 for granulomatous disease outside the skin and subcutaneous tissue. Also avoid it when documentation supports a different, more specific diagnosis. Check documentation.
Coding tip
Code the most specific documented granulomatous skin diagnosis, and query if the note only says “granuloma” without a clear site or type.
