D09.20 - Carcinoma in situ of unspecified eye
| ICD-10: | D09.20 |
| Short Description: | Carcinoma in situ of unspecified eye |
| Long Description: | Carcinoma in situ of unspecified eye |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
D09.20 is a billable ICD-10 code used to specify a medical diagnosis of carcinoma in situ of unspecified eye. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following anatomical sites found in the Table of Neoplasms reference the parent code D09.2 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic choroid ; Neoplasm, neoplastic ciliary body ; Neoplasm, neoplastic conjunctiva ; Neoplasm, neoplastic connective tissue NEC orbit ; Neoplasm, neoplastic cornea (limbus) ; Neoplasm, neoplastic crystalline lens ; Neoplasm, neoplastic extraocular muscle ; etc
Unspecified diagnosis codes like D09.20 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Table of Neoplasms
The parent code D09.2 of the current diagnosis code is referenced 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.

Patient Education
Eye Cancer
Cancer of the eye is uncommon. It can affect the outer parts of the eye, such as the eyelid, which are made up of muscles, skin and nerves. If the cancer starts inside the eyeball it's called intraocular cancer. The most common intraocular cancers in adults are melanoma and lymphoma. The most common eye cancer in children is retinoblastoma, which starts in the cells of the retina. Cancer can also spread to the eye from other parts of the body.
Treatment for eye cancer varies by the type and by how advanced it is. It may include surgery, radiation therapy, freezing or heat therapy, or laser therapy.
