ICD-10-CM Code H40
Glaucoma
Non-Billable Code
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 is a non-billable code. To code a diagnosis of this type, you must use one of the nine child codes of H40 that describes the diagnosis 'glaucoma' in more detail.

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. 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 involves sudden eye pain, blurred vision, mid-dilated pupil, redness, nausea and vomiting, resulting from a sudden spike in intraocular pressure from iridotrabecular contact. Glaucoma can permanently damage vision in the affected eye, first by decreasing peripheral vision (reducing the visual field), and then potentially leading to blindness if left untreated.
Specialty: | Ophthalmology |
MeSH Code: | D005901 |
ICD 9 Code: | 365 |
Acute angle closure glaucoma of the right eye. Note the mid-sized pupil, which was nonreactive to light, and redness of the conjunctiva.

Code Type-1 Excludes:
Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here." - Absolute glaucoma - instead, use code H44.51-
- Congenital glaucoma - instead, use code Q15.0
- Traumatic glaucoma due to birth injury - instead, use code P15.3
