ICD-10 Code D03.61 – Melanoma in situ of right upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D03.61 – Melanoma in situ of right upper limb, including shoulder
What it is
D03.61 identifies melanoma in situ on the right upper limb, including the shoulder. The lesion is confined to the epidermis and has not invaded deeper tissue.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see an irregular pigmented lesion with asymmetry, border variation, or color change, but pathology confirmation is required for in situ melanoma.
When to use this code
Use this code when the record states melanoma in situ on the right arm, forearm, hand, or shoulder, and the site is clearly documented as right-sided. Choose it when the diagnosis is confirmed as in situ, not invasive.
If laterality or exact anatomic location is unclear, check documentation before coding. Use the pathology or clinician note to support the diagnosis and site assignment.
Do not use for
Do not use D03.61 for invasive melanoma, unspecified laterality, or lesions on other body sites. Do not use it when the chart only says suspicious mole or atypical nevus.
Coding tip
Verify both the in situ status and the right upper-limb site in the pathology or provider note before assigning D03.61.
