ICD-10 Code C44.1192 – Basal cell carcinoma of skin of left lower eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.1192 – Basal cell carcinoma of skin of left lower eyelid, including canthus
What it is
This code identifies basal cell carcinoma arising on the skin of the left lower eyelid, including the canthus. Use it when the documented primary site is that specific eyelid area.
Clinical signs
Basal cell carcinoma often appears as a slow-growing pearly or translucent lesion, a nonhealing sore, or a raised nodule that may bleed or crust. Clinical features vary; refer to documentation.
When to use this code
Use C44.1192 when the provider documents basal cell carcinoma of the left lower eyelid, with or without canthus involvement on that same side. This is appropriate for confirmed malignant skin lesions at that exact site. If the record only says “eyelid” or does not specify laterality, check documentation before assigning this code.
Do not use for
Do not use this code for lesions on the upper eyelid, right eyelid, or unspecified eyelid. It is also not for nonmalignant skin lesions or other eye-adjacent tumors.
Coding tip
Verify both laterality and the exact eyelid location, because a missing site detail can change the code.
