ICD-10-CM Code C44.12

Squamous cell carcinoma of skin of eyelid, including canthus

Version 2021 Non-Billable Code Neoplasm Malignant Primary

Not Valid for Submission

C44.12 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of squamous cell carcinoma of skin of eyelid, including canthus. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic canthus (eye) (inner) (outer) squamous cell carcinoma ; Neoplasm, neoplastic eyelid (lower) (skin) (upper) squamous cell carcinoma ; Neoplasm, neoplastic lid (lower) (upper) squamous cell carcinoma ; Neoplasm, neoplastic meibomian gland squamous cell carcinoma ; Neoplasm, neoplastic palpebra squamous cell carcinoma ; Neoplasm, neoplastic skin NOS canthus (eye) (inner) (outer) squamous cell carcinoma ; Neoplasm, neoplastic skin NOS eyelid squamous cell carcinoma ; etc

ICD-10:C44.12
Short Description:Squamous cell carcinoma of skin of eyelid, including canthus
Long Description:Squamous cell carcinoma of skin of eyelid, including canthus

Consider the following ICD-10 codes with a higher level of specificity:

  • C44.121 - Squamous cell carcinoma of skin of unspecified eyelid, including canthus
  • C44.122 - Squamous cell carcinoma of skin of right eyelid, including canthus
  • C44.1221 - Squamous cell carcinoma of skin of right upper eyelid, including canthus
  • C44.1222 - Squamous cell carcinoma of skin of right lower eyelid, including canthus
  • C44.129 - Squamous cell carcinoma of skin of left eyelid, including canthus
  • C44.1291 - Squamous cell carcinoma of skin of left upper eyelid, including canthus
  • C44.1292 - Squamous cell carcinoma of skin of left lower eyelid, including canthus

Code Classification

  • Neoplasms (C00–D48)

Table of Neoplasms

The code C44.12 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Eyelid Disorders

Your eyelids help protect your eyes. When you blink, your eyelids spread moisture over your eyes. Blinking also helps move dirt or other particles off the surface of the eye. You close your eyelids when you see something coming toward your eyes. This can help protect against injuries.

Like most other parts of your body, your eyelids can get infected, inflamed, or even develop cancer. There are also specific eyelid problems, including

  • Eyelids that turn in or out
  • Eyelids that droop
  • Abnormal blinking or twitching

Treatment of eyelid problems depends on the cause.

Skin Cancer

Skin cancer is the most common form of cancer in the United States. The two most common types are basal cell cancer and squamous cell cancer. They usually form on the head, face, neck, hands, and arms. Another type of skin cancer, melanoma, is more dangerous but less common.

Anyone can get skin cancer, but it is more common in people who

  • Spend a lot of time in the sun or have been sunburned
  • Have light-colored skin, hair and eyes
  • Have a family member with skin cancer
  • Are over age 50

You should have your doctor check any suspicious skin markings and any changes in the way your skin looks. Treatment is more likely to work well when cancer is found early. If not treated, some types of skin cancer cells can spread to other tissues and organs. Treatments include surgery, radiation therapy, chemotherapy, photodynamic therapy (PDT), and biologic therapy. PDT uses a drug and a type of laser light to kill cancer cells. Biologic therapy boosts your body's own ability to fight cancer.
