H21.269 is a billable ICD-10 code used to specify a medical diagnosis of iris atrophy (essential) (progressive), 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 H21.269 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:
- Atrophic iris
- Chandler syndrome
- Generalized iris atrophy
- Iridocorneal endothelial syndrome
- Progressive iris atrophy
- Secondary iris atrophy
- Sector shaped iris atrophy
- Traumatic iris atrophy
- Iridocorneal Endothelial Syndrome-. a grouping of three closely linked conditions: iris nevus (or cogan-reese) syndrome, chandler syndrome, and essential (progressive) iris atrophy. the most common features of this syndrome are the movement of endothelial cells off the cornea onto the iris leading to corneal swelling, distortion of the iris, and variable degrees of distortion of the pupil. the abnormal cell movement plugs fluid outflow channels of the eye causing glaucoma.
- Glaucoma-. an ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. the consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (dictionary of visual science, 4th ed)
- Iridocorneal Endothelial Syndrome-. a group of disorders characterized by the presence of an abnormal inner layer of the cornea. this abnormality results in iris distortion, corneal swelling, pupil distortion, and glaucoma. it usually affects only one eye.

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.
