Primary open-angle glaucoma, left eye, moderate stage. H40.1122 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM H40.1122 became effective on October 1, 2019.
Primary open-angle glaucoma, bilateral, moderate stage Billable Code H40.1132 is a valid billable ICD-10 diagnosis code for Primary open-angle glaucoma, bilateral, moderate stage. It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021.
Update: The AGS tutorial on grading the severity of glaucoma is now available. Other common eye diseases have them; why not glaucoma? That is, codes indicating disease severity. ICD-9 severity codes already exist for macular degeneration, diabetic retinopathy, cataract and even retinopathy of prematurity.
Both patients have primary open-angle glaucoma. The first has minimal damage that requires one medication and follow-up visits twice a year; the second has advanced disease that requires multiple medications, numerous visits and surgery.
ICD-10 code H40. 113 for Primary open-angle glaucoma, bilateral is a medical classification as listed by WHO under the range - Diseases of the eye and adnexa .
ICD-10-CM Code for Primary open-angle glaucoma, bilateral, moderate stage H40. 1132.
ICD-10-CM Code for Primary open-angle glaucoma, right eye, mild stage H40. 1111.
H40. 1111 - Primary open-angle glaucoma, right eye [mild stage] is a topic covered in the ICD-10-CM.
Primary open angle glaucoma (POAG) is a subset of the glaucomas defined by an open, normal appearing anterior chamber angle and raised intraocular pressure (IOP), with no other underlying disease. If there is an identifiable underlying cause for raised IOP, this is termed secondary glaucoma.

Moderate stage glaucoma is noted with a “2” as the final digit in the diagnosis code. As in the example above, moderate stage open angle glaucoma with borderline findings and low risk the ICD-10 code would be H40. 011X2 for the right eye and H40. 012X2 for the left eye.
The Enhanced Glaucoma Severity Staging system (eGSS). EGSS has a total of 7 stages: 0, the border between 0 & 1, 1, 2, 3, 4 and 5, where stage 0 are fields with no defect and stage 4 are fields with the greatest defect.
5 Glaucoma secondary to other eye disorders.
One way to think of the glaucomas is in five stages: 1) an initial sequence of events, which cause 2) alterations in the aqueous outflow system, which result in 3) elevated IOP, which leads to 4) atrophy of the optic nerve and 5) progressive loss of the visual field.
If left untreated, glaucoma will eventually cause blindness. Even with treatment, about 15 percent of people with glaucoma become blind in at least one eye within 20 years.
There are many ways to classify glaucoma, but there are generally four categories or types of glaucoma. The four types are Primary Open Angle Glaucoma, Angle Closure Glaucoma, Normal Tension Glaucoma, and Secondary Glaucoma.
Pseudoexfoliation syndrome (other names: Exfoliation glaucoma, Pseudoexfoliation glaucoma, Pseudoexfoliation of the lens, Exfoliation syndrome), sometimes abbreviated as PEX, is an aging–related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. Its cause is unknown, although there is speculation that there may be a genetic basis. It is more prevalent in women than men, and in persons past the age of seventy. Its prevalence in different human populations varies; for example, it is prevalent in Scandinavia. The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision. As worldwide populations become older because of shifts in demography, PEX may become a matter of greater concern.
