H21.239 is a billable ICD-10 code used to specify a medical diagnosis of degeneration of iris (pigmentary), 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.
Unspecified diagnosis codes like H21.239 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Acquired heterochromia of iris
- Age-related changes in iris
- Degeneration of iris
- Iris and ciliary body degeneration
- Pigment dispersion syndrome
- Translucency of iris
- Vitiligo iridis
- Pigment Dispersion Syndrome-. condition where iris pigment is released into the anterior chamber and deposited in the trabecular meshwork, due to a procedure or device implantation.

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.
Common eye problems include:
- Refractive errors
- Cataracts - clouded lenses
- Optic nerve disorders, including glaucoma
- Retinal disorders - problems with the nerve layer at the back of the eye
- Macular degeneration - a disease that destroys sharp, central vision
- Diabetic eye problems
- Conjunctivitis - an infection also known as pink eye
Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.
