Neovascular secondary angle closure glaucoma

ICD-10-CM Code:

H40.84

ICD-10 Code for:

Neovascular secondary angle closure glaucoma

Is Billable?

Not Valid for Submission

Code Navigator:

H40.84 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of neovascular secondary angle closure glaucoma. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Non-specific codes like H40.84 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for neovascular secondary angle closure glaucoma:

Use H40.841 for Neovascular secondary angle closure glaucoma, right eye

Use H40.842 for Neovascular secondary angle closure glaucoma, left eye

Use H40.843 for Neovascular secondary angle closure glaucoma, bilateral

Use H40.849 for Neovascular secondary angle closure glaucoma, unspecified eye

the deposition of flaky, translucent fibrillar material most conspicuous on the anterior lens capsule and pupillary margin but also in both surfaces of the iris, the zonules, trabecular meshwork, ciliary body, corneal endothelium, and orbital blood vessels. it sometimes forms a membrane on the anterior iris surface. exfoliation refers to the shedding of pigment by the iris. (newell, ophthalmology, 7th ed, p380)

an ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. the consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (dictionary of visual science, 4th ed)

devices, usually incorporating unidirectional valves, which are surgically inserted in the sclera to maintain normal intraocular pressure.

a form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber.

a form of secondary glaucoma which develops as a consequence of another ocular disease and is attributed to the forming of new vessels in the angle of the anterior chamber.

glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.

a form of glaucoma in which chronic optic nerve damage and loss of vision normally attributable to buildup of intraocular pressure occurs despite prevailing conditions of normal intraocular pressure.

a condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.

rare congenital disorder of connective tissue characterized by brachydactyly, joint stiffness, childhood onset of ocular abnormalities (e.g., microspherophakia, ectopia lentis; glaucoma), and proportionate short stature. cardiovascular anomalies are occasionally seen.
