2018/2019 ICD-10-CM Diagnosis Code H40.21. Acute angle-closure glaucoma. H40.21 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.

Acute angle-closure glaucoma is an ocular emergency that results from a rapid increase in intraocular pressure due to outflow obstruction of aqueous humor.
Closed angle glaucoma is also known as acute angle closure glaucoma or narrow angle glaucoma and is not very common. It occurs when the patient's iris is near the drainage angle in their eye. As a result, the iris can ultimately block that drainage angle which leads to the increase of eye pressure at a fast pace.
Angle-closure glaucoma, also called closed-angle glaucoma, occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris. As a result, fluid can't circulate through the eye and pressure increases.
In open-angle glaucoma, the iris is in the right position, and the uveoscleral drainage canals are clear. But the trabecular meshwork isn't draining properly. In closed-angle glaucoma, the iris is squeezed against the cornea, blocking the uveoscleral drains and the trabecular meshwork.
Acute angle closure is an urgent, dramatic symptomatic event accompanied by blurred vision, painful red eye, headache, nausea, and vomiting. It is diagnosed by high IOP, corneal edema, shallow anterior chamber depth, and a closed angle on gonioscopy.
Angle-closure glaucoma, also called narrow-angle or acute glaucoma, is a medical emergency. Go to the doctor or emergency room immediately if you suddenly have: Intense eye pain. Upset stomach (nausea)
Acute angle-closure glaucoma is caused by a rapid or sudden increase in pressure inside the eye, called intraocular pressure (IOP).
The ICD code H40 is used to code Glaucoma. Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. A major risk factor is increased pressure in the eye. The disorders can be roughly divided into two main categories: "open-angle" and "closed-angle" (or "angle closure") glaucoma.
H40.21. Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail. ICD Code H40.21 is a non-billable code.
Open-angle chronic glaucoma is painless, tends to develop slowly over time and often has no symptoms until the disease has progressed significantly. Closed angle glaucoma is usually chronic and asymptomatic but can present all of a sudden as well.

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code H40.213 and a single ICD9 code, 365.22 is an approximate match for comparison and conversion purposes.
