ICD-10 Code C86.30 – Subcutaneous panniculitis-like T-cell lymphoma not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C86.30 – Subcutaneous panniculitis-like T-cell lymphoma not having achieved remission
What it is
This code identifies subcutaneous panniculitis-like T-cell lymphoma that is still active and has not achieved remission. It is a rare cutaneous T-cell lymphoma that primarily involves the fat beneath the skin.
Clinical signs
Typical findings include tender subcutaneous nodules or plaques, often on the legs or trunk. Clinical features vary; refer to documentation, and confirm that the lymphoma is described as not in remission.
When to use this code
Use C86.30 when the record specifically states subcutaneous panniculitis-like T-cell lymphoma and indicates the disease has not achieved remission. Apply it for active disease at diagnosis, persistent disease after treatment, or ongoing management when remission is not documented. Check documentation if the remission status is unclear.
Do not use for
Do not use this code for other cutaneous lymphomas, panniculitis without lymphoma, or cases documented as remission. If the provider does not state the lymphoma subtype or remission status, check documentation.
Coding tip
Code the exact lymphoma subtype and remission status together; if either element is missing, query the provider before assigning C86.30.
