Carcinoma in situ of skin of left upper eyelid, including canthus
ICD-10 D04.121 is a billable code used to indicate a diagnosis of carcinoma in situ of skin of left upper eyelid, including canthus.
Carcinoma in situ (CIS) of the skin is a non-invasive form of skin cancer characterized by the presence of abnormal cells confined to the epidermis. In the case of D04.121, the carcinoma is specifically located on the left upper eyelid, including the canthus, which is the corner of the eye where the upper and lower eyelids meet. This condition is often asymptomatic in its early stages but can present as a persistent lesion, ulcer, or change in skin color. Risk factors include excessive sun exposure, fair skin, and a history of skin cancer. Surveillance protocols typically involve regular dermatological examinations to monitor for changes in the lesion's appearance or size. 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.
Detailed descriptions of the lesion, including size, color, and texture, as well as treatment plans and follow-up.
Diagnosis and management of skin lesions, including biopsies and excisions.
Ensure accurate documentation of the lesion's location and characteristics to support the diagnosis.
Documentation of ocular examination findings, including any impact on vision or eyelid function.
Management of eyelid lesions and their potential impact on ocular health.
Collaboration with dermatology for comprehensive care and accurate coding.
Used when excising a carcinoma in situ lesion.
Document the size and location of the lesion, as well as the excision details.
Dermatology and ophthalmology may both be involved in the excision.
Accurate coding of D04.121 is crucial for appropriate treatment planning, reimbursement, and tracking of skin cancer incidence. It ensures that patients receive the necessary follow-up care and interventions.
