ICD-10 Code L92.9 – Granulomatous disorder of the skin and subcutaneous tissue, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L92.9 – Granulomatous disorder of the skin and subcutaneous tissue, unspecified
What it is
L92.9 identifies a granulomatous disorder affecting the skin and subcutaneous tissue when the specific type is not documented. Use it for a nonspecific granulomatous inflammatory process limited to these tissues.
Clinical signs
Findings may include firm papules, nodules, plaques, or localized skin thickening. Clinical features vary; refer to documentation for the exact appearance, distribution, and any pathology results supporting a granulomatous process.
When to use this code
Use this code when the provider documents a granulomatous disorder of the skin or subcutaneous tissue but does not name a more specific diagnosis. It also fits cases where pathology confirms granulomatous inflammation and the final site-specific diagnosis remains unspecified. If the record names a specific granulomatous disease, code that condition instead.
Do not use for
Do not use L92.9 for granulomatous disorders outside the skin and subcutaneous tissue, or when the chart identifies a more specific entity. Check documentation if the lesion is infectious, systemic, or otherwise classified elsewhere.
Coding tip
Code the documented specificity first; use L92.9 only when the record supports a granulomatous skin disorder but leaves the exact type unspecified.
