What it is
C44.139 identifies a malignant sebaceous gland tumor of the skin on the left eyelid, including the canthus. Use it when documentation specifies this exact site and tumor type.
Clinical signs
Typical findings include a persistent eyelid nodule, thickening, or a lesion that does not heal. Clinical features vary; refer to documentation for confirmed pathology and laterality.
When to use this code
Use this code when the provider documents sebaceous cell carcinoma involving the left upper or lower eyelid, or the canthus. It is appropriate for confirmed primary skin malignancy at this exact location. If the note is nonspecific, check documentation before coding.
Do not use for
Do not use it for benign eyelid lesions, other eyelid cancers, or tumors on the right eyelid. Do not substitute it for an unspecified skin cancer when the site or histology is not documented.
Coding tip
Verify both histology and laterality in the pathology or operative note before assigning C44.139.
