Valid for Submission
H40.52X0 is a billable diagnosis code used to specify a medical diagnosis of glaucoma secondary to other eye disorders, left eye, stage unspecified. The code H40.52X0 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H40.52X0 might also be used to specify conditions or terms like aphakic glaucoma, aphakic glaucoma of left eye, glaucoma associated with vascular disorder, glaucoma due to chamber angle anomaly, glaucoma due to ocular vascular disorder , glaucoma of left eye due to anterior segment anomaly, etc.
Unspecified diagnosis codes like H40.52X0 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:
- Aphakic glaucoma
- Aphakic glaucoma of left eye
- Glaucoma associated with vascular disorder
- Glaucoma due to chamber angle anomaly
- Glaucoma due to ocular vascular disorder
- Glaucoma of left eye due to anterior segment anomaly
- Glaucoma of left eye due to chamber angle anomaly
- Glaucoma of left eye due to lens disorder
- Glaucoma of left eye due to ocular vascular disorder
- Neovascular glaucoma
- Neovascular glaucoma of left eye
- Neovascularization of angle
- Phacogenic glaucoma

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.
