ICD-10 Code D04.61 – Carcinoma in situ of skin of right upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D04.61 – Carcinoma in situ of skin of right upper limb, including shoulder
What it is
This code identifies a noninvasive skin cancer confined to the epidermis on the right upper limb, including the shoulder. The lesion has not breached the basement membrane, so it is still in situ.
Clinical signs
Clinical features vary; refer to documentation. You may see a persistent scaly, crusted, or erythematous skin lesion, often biopsied to confirm carcinoma in situ without invasion.
When to use this code
Use D04.61 when the provider documents carcinoma in situ of skin specifically on the right upper limb or shoulder. The record should support a noninvasive malignant lesion at that site, usually based on pathology or clear clinical diagnosis.
Choose this code when the anatomic location is documented as right arm, forearm, hand, or shoulder and the lesion is not described as invasive. Check documentation if laterality or site is unclear.
Do not use for
Do not use this code for invasive skin cancer, benign lesions, or carcinoma in situ at a different body site. If the chart does not specify right-sided location, check documentation before coding.
Coding tip
Verify both laterality and exact site; D04.61 requires right upper limb, including shoulder.
