ICD-10 Code C44.49 – Other specified malignant neoplasm of skin of scalp and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.49 – Other specified malignant neoplasm of skin of scalp and neck
What it is
This code identifies a malignant skin tumor of the scalp or neck that is not otherwise classified in a more specific ICD-10-CM skin cancer category. Use it when the record names a malignant neoplasm but does not specify a different skin cancer type.
Clinical signs
Clinical features vary; refer to documentation. Typical findings for skin malignancy may include a persistent lesion, abnormal growth, ulceration, bleeding, or a nonhealing area on the scalp or neck.
When to use this code
Use C44.49 when the provider documents a malignant neoplasm of the skin on the scalp or neck and the diagnosis is not captured by a more specific code. It is appropriate when the pathology or note supports malignancy but does not identify a precise skin cancer subtype. Check documentation if the site or histology is unclear.
Do not use for
Do not use this code for benign skin lesions, premalignant changes, or unspecified skin cancers without the “other specified” wording. If the record identifies a different primary skin cancer type, code that diagnosis instead.
Coding tip
Verify both the anatomic site and the exact wording in the pathology or provider note before assigning C44.49.
