C44.1392 Sebaceous cell carcinoma of skin of left lower eyelid, including canthus

ICD-10-CM C44.1392: Sebaceous Cell Carcinoma of Skin of Left Lower Eyelid, Including Canthus

ICD-10-CM code C44.1392 identifies sebaceous cell carcinoma of the skin of the left lower eyelid, including the canthus. Public sources establish this as a specific diagnosis code within the eyelid malignant neoplasm category. Clinical literature notes that sebaceous carcinoma is an eyelid malignancy originating from sebaceous glands, with ocular sites being a frequent location for this disease. 3 4 5 6 1 2

Plain-language overview

Sebaceous carcinoma is a malignant eyelid tumor, and public clinical literature identifies the ocular region as a frequent site for this disease. The World Health Organization classifies this condition into periocular and extraocular categories, with the periocular type primarily affecting the eyelid. 1 2

What this code represents

ICD-10-CM code C44.1392 denotes sebaceous cell carcinoma of the skin of the left lower eyelid, including the canthus. Official terminology sources and Medicare billing references list this exact alphanumeric designation and description for this specific diagnosis. 3 4 5

Coding details

Within the ICD-10-CM code tree, C44.1392 falls under the broader category of other and unspecified malignant neoplasms of skin of the eyelid. The code tree structure shows C44.1392 as a specific descendant of sebaceous cell carcinoma of the left eyelid. 6

The ICD-10-CM code tree distinguishes C44.1392 from adjacent codes by laterality and anatomical position. The structure provides separate codes for the right lower eyelid, left upper eyelid, and unspecified eyelid sebaceous cell carcinomas. 6

Clinical context

Tumors of sebaceous glands in the ocular region originate in structures such as the meibomian glands and the glands of Zeis. The upper eyelid is identified as the most common site for sebaceous carcinoma due to the dense concentration of meibomian glands. 2

Periocular sebaceous carcinoma ranks as the third most prevalent eyelid malignancy after basal cell carcinoma and squamous cell carcinoma. The disease exhibits distinct epidemiological patterns, with the neoplasm accounting for a higher percentage of eyelid tumors in Asia compared to resource-rich nations. 1 2

Documentation considerations

The ICD-10-CM code tree provides distinct alphanumeric codes for sebaceous cell carcinoma of the left lower eyelid, the left upper eyelid, and the right lower eyelid. This structural differentiation allows for the classification of the specific anatomical site documented in the health record. 6

What the sources add

A Medicare billing and coding article includes C44.1392 within a list of diagnosis codes associated with the removal of benign and malignant skin lesions. A laboratory reference document also lists C44.1392 as a valid diagnosis code alongside other malignant neoplasm codes. 4 5
