ICD-10-CM Code H40.2
Primary angle-closure 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 H40.2 is a non-billable code. To code a diagnosis of this type, you must use one of the five child codes of H40.2 that describes the diagnosis 'primary angle-closure 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.

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." - Aqueous misdirection - instead, use code H40.83-
- Malignant glaucoma - instead, use code H40.83-
