Carcinoma in situ of skin of left eyelid, including canthus
ICD-10 D04.12 is a billable code used to indicate a diagnosis of carcinoma in situ of skin of left eyelid, including canthus.
Carcinoma in situ (CIS) of the skin of the left eyelid, including the canthus, represents a localized form of skin cancer where abnormal cells are present but have not invaded deeper tissues. This condition is characterized by atypical keratinocytes confined to the epidermis, which can arise from various factors including UV exposure, genetic predisposition, and other environmental influences. The left eyelid, being a delicate area, requires careful monitoring due to its proximity to the eye and the potential for cosmetic and functional impairment. Surveillance protocols typically involve regular dermatological examinations, with a focus on any changes in the lesion's appearance, size, or symptoms such as itching or bleeding. The risk of progression to invasive carcinoma is present, particularly if left untreated, necessitating timely intervention. Treatment options may include surgical excision, cryotherapy, or topical chemotherapy, depending on the lesion's characteristics and patient factors. Continuous follow-up is essential to ensure early detection of any changes that may indicate progression.
Detailed descriptions of the lesion, including size, color, and any changes over time.
Initial diagnosis of carcinoma in situ, treatment planning, and follow-up evaluations.
Ensure clear documentation of the in situ status to avoid misclassification.
Documentation of any ocular involvement or impact on vision.
Assessment of eyelid lesions and coordination with dermatology for treatment.
Consider the functional implications of eyelid lesions on vision and ocular health.
Used when excising a carcinoma in situ from the left eyelid.
Document the size of the lesion and the margins excised.
Ensure coordination between dermatology and ophthalmology for eyelid lesions.
Carcinoma in situ is a critical diagnosis as it indicates the presence of abnormal cells that have not invaded surrounding tissues. Early detection and treatment are essential to prevent progression to invasive cancer.
