ICD-10 Code C86.61 – Primary cutaneous CD30-positive T-cell proliferations, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C86.61 – Primary cutaneous CD30-positive T-cell proliferations, in remission
What it is
This code identifies a primary cutaneous CD30-positive T-cell proliferation that is documented as in remission. Use it when the skin-based lymphoma or related disorder is no longer active, but the condition remains part of the patient’s history.
Clinical signs
Clinical features vary; refer to documentation. These disorders typically involve cutaneous lesions with CD30-positive T-cell findings on pathology, and remission means active disease is not currently present.
When to use this code
Use this code when the provider documents primary cutaneous CD30-positive T-cell proliferation and clearly states remission. It is appropriate for follow-up visits, surveillance, or history review when no active skin disease is being treated. Check documentation if the record only notes prior disease without remission status.
Do not use for
Do not use this code for active primary cutaneous CD30-positive T-cell disease or for unspecified lymphoma history. If the record does not confirm remission, check documentation before coding.
Coding tip
Code the remission status only when the provider explicitly documents it; otherwise, query for clarification.
