ICD-10 Code C44.119 – Basal cell carcinoma of skin of left eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.119 – Basal cell carcinoma of skin of left eyelid, including canthus
What it is
This code identifies basal cell carcinoma located on the skin of the left eyelid, including the canthus. Use it when documentation specifies this exact site and confirms a basal cell skin cancer.
Clinical signs
Typical findings include a slowly enlarging eyelid lesion, often pearly, translucent, ulcerated, or crusted. Clinical features vary; refer to documentation, especially when the canthus is involved.
When to use this code
Use C44.119 when the provider documents basal cell carcinoma of the left upper or lower eyelid, or the left canthus, and the record does not specify a more detailed subsite. It is appropriate for confirmed primary skin malignancy at this location.
If laterality or eyelid subsite is unclear, check documentation before coding. Code the documented anatomic site exactly as stated and avoid assuming right-sided or unspecified eyelid involvement.
Do not use for
Do not use this code for benign eyelid lesions, non-melanoma skin cancers at other sites, or cancers of the eyelid that are not basal cell carcinoma. Check documentation if the lesion is not clearly on the left eyelid or canthus.
Coding tip
Verify laterality and whether the canthus is included, because eyelid skin cancers are coded by exact documented site.
