ICD-10 Code C44.4 – Other and unspecified malignant neoplasm of skin of scalp and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.4 – Other and unspecified malignant neoplasm of skin of scalp and neck
What it is
This code identifies a malignant skin tumor located on the scalp or neck when the exact skin cancer type is not specified or is documented as other. Use it for primary skin malignancies in that anatomic area.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a persistent skin lesion, nonhealing ulcer, bleeding, crusting, or a changing pigmented or raised area on the scalp or neck.
When to use this code
Use C44.4 when the provider documents a malignant neoplasm of skin on the scalp or neck and does not name a more specific histology. It also applies when the record states “other” or “unspecified” skin cancer in this site. Check documentation for laterality or more specific site detail if available.
Do not use for
Do not use this code for benign skin lesions, premalignant changes, or non-skin cancers involving the scalp or neck. If the diagnosis is a more specific skin cancer type or a different anatomic site, code that diagnosis instead.
Coding tip
Verify the pathology or provider wording first; if the histology is named, choose the more specific ICD-10-CM code.
