2025 ICD-10-CM code H47.23

Glaucomatous optic atrophy.

Code assignment should reflect the laterality (right eye, left eye, or bilateral) of the glaucomatous optic atrophy.Use additional codes as needed to describe associated findings or complications.

Modifiers may be applicable to indicate the laterality of the condition or the circumstances of the visit.Consult current coding guidelines for specific modifier usage.

The medical necessity for coding H47.23 is established by the presence of glaucomatous optic atrophy, confirmed through clinical examination and appropriate diagnostic testing.The severity of the condition and its impact on the patient's vision justify the use of this code for billing and reimbursement purposes.

Ophthalmologist or other qualified eye care professional

IMPORTANT:H47.231 (Glaucomatous optic atrophy, right eye), H47.232 (Glaucomatous optic atrophy, left eye), H47.233 (Glaucomatous optic atrophy, bilateral)may be used depending on laterality.

In simple words: Glaucomatous optic atrophy is damage to the optic nerve (the nerve connecting the eye to the brain) due to high pressure inside the eye (from glaucoma). This damage can cause vision loss.

Glaucomatous optic atrophy is a condition characterized by damage to the optic nerve caused by increased intraocular pressure associated with glaucoma.This damage leads to the degeneration of retinal ganglion cells and their axons, resulting in visual field loss and potential blindness.

Example 1: A 65-year-old male patient with a history of open-angle glaucoma presents with progressive vision loss in his right eye.Ophthalmoscopic examination reveals cupping of the optic disc and pallor, consistent with glaucomatous optic atrophy. Visual field testing confirms a significant defect in the right visual field., A 70-year-old female patient with poorly controlled glaucoma exhibits bilateral visual field defects and optic disc pallor.Optical coherence tomography (OCT) demonstrates thinning of the retinal nerve fiber layer, further supporting the diagnosis of glaucomatous optic atrophy., A 58-year-old patient with normal-tension glaucoma experiences insidious vision loss.Fundus photography and visual field testing indicate the presence of glaucomatous optic atrophy despite normal intraocular pressure.

* Comprehensive ophthalmologic examination including visual acuity, intraocular pressure measurement, ophthalmoscopy, visual field testing, and optical coherence tomography (OCT).* Documentation of glaucoma diagnosis and treatment history.* Detailed description of the extent and severity of optic nerve damage.* Relevant imaging studies (e.g., OCT, fundus photography).

** This code is used to report glaucomatous optic atrophy, a specific type of optic nerve damage caused by glaucoma.It is important to differentiate this from other causes of optic atrophy.
