ICD-10 Code C44.7 – Other and unspecified malignant neoplasm of skin of lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.7 – Other and unspecified malignant neoplasm of skin of lower limb, including hip
What it is
This code identifies a malignant skin cancer located on the lower limb, including the hip, when the exact skin cancer type is not further specified. Use it for documented malignant neoplasms of skin in that anatomic region.
Clinical signs
Clinical features vary; refer to documentation. Skin cancers may appear as a nonhealing lesion, changing pigmented area, ulcer, or enlarging mass on the lower limb or hip.
When to use this code
Use C44.7 when the provider documents a malignant neoplasm of the skin on the lower limb or hip and does not name a more specific site code. It also fits cases where the record says “other” or “unspecified” skin cancer in that region. Check documentation if the lesion is deeper than skin or the primary site is elsewhere.
Do not use for
Do not use this code for benign skin lesions, in situ skin neoplasms, or cancers arising from non-skin tissue. If the documentation identifies a more specific skin site or histology, code that instead.
Coding tip
Confirm the lesion is documented as skin and located on the lower limb or hip before assigning C44.7.
