ICD-10-CM Code H40.50X0
Glaucoma secondary to other eye disorders, unspecified eye, stage unspecified
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.H40.50X0 is a billable ICD code used to specify a diagnosis of glaucoma secondary to other eye disorders, unspecified eye, stage unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
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.

Acute angle closure glaucoma of the right eye. Note the mid-sized pupil, which was nonreactive to light, and redness of the conjunctiva.

Coding Advice SNOMET-CT
- Consider laterality specification
- Consider stage of glaucoma specification
- Consider additional code to identify specific condition or disease
- This is a manifestation code for use in a secondary position
Equivalent ICD-9 Codes GENERAL EQUIVALENCE MAPPINGS (GEM)
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 H40.50X0 and a single ICD9 code, 365.70 is an approximate match for comparison and conversion purposes.
