2026 ICD-10-CM Diagnosis Code C44.612 – Basal cell carcinoma of skin of right upper limb, including shoulder
What it is
This code identifies a basal cell carcinoma arising on the skin of the right upper limb, including the shoulder. Use it when documentation specifies this exact site and the lesion is basal cell carcinoma.
Clinical signs
Basal cell carcinoma often appears as a pearly papule, a nonhealing sore, or a lesion with rolled borders and surface bleeding. Clinical features vary; refer to documentation.
When to use this code
Use C44.612 when the provider documents basal cell carcinoma on the right arm, forearm, hand, or shoulder skin, and the laterality is right. It is appropriate for confirmed diagnosis, pathology-supported diagnosis, or clearly documented clinical diagnosis of this site. If the record says only “skin cancer” or does not specify the site, check documentation.
Do not use for
Do not use this code for basal cell carcinoma on the left upper limb, trunk, face, or lower limb. Do not assign it for unspecified skin cancer or when the lesion is not documented as basal cell carcinoma.
Coding tip
Confirm both histology and exact right-sided upper-limb location before assigning this code.
