Valid for Submission
H40.2292 is a billable diagnosis code used to specify a medical diagnosis of chronic angle-closure glaucoma, unspecified eye, moderate stage. The code H40.2292 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like H40.2292 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.

Information for Patients
Glaucoma is a group of diseases that can damage the eye's optic nerve. It is a leading cause of blindness in the United States. It usually happens when the fluid pressure inside the eyes slowly rises, damaging the optic nerve. Often there are no symptoms at first. Without treatment, people with glaucoma will slowly lose their peripheral, or side vision. They seem to be looking through a tunnel. Over time, straight-ahead vision may decrease until no vision remains.
A comprehensive eye exam can tell if you have glaucoma. People at risk should get eye exams at least every two years. They include
- African Americans over age 40
- People over age 60, especially Mexican Americans
- People with a family history of glaucoma
There is no cure, but glaucoma can usually be controlled. Early treatment can help protect your eyes against vision loss. Treatments usually include prescription eyedrops and/or surgery.
