2025 ICD-10-CM code H47.232

Glaucomatous optic atrophy of the left eye.

Use an external cause code following the code for the eye condition, if applicable, to identify the cause of the eye condition. Do not use codes from certain chapters like perinatal period, infectious and parasitic diseases, diabetes mellitus related eye conditions if related to this diagnosis.

Medical necessity for services related to glaucomatous optic atrophy is established by the presence of documented vision loss and optic nerve damage due to glaucoma.The medical record should support the need for ongoing monitoring, treatment, or other interventions to manage the condition and prevent further vision loss.

Diagnosis and management of this condition falls under the purview of ophthalmologists.They are responsible for evaluating the extent of optic nerve damage,managing intraocular pressure, and recommending appropriate treatment strategies to slow the progression of vision loss.

In simple words: Damage to the optic nerve in the left eye caused by glaucoma, leading to vision loss.

Glaucomatous optic atrophy, left eye

Example 1: A 65-year-old patient with a history of primary open-angle glaucoma presents with progressive vision loss in their left eye. Upon examination, the ophthalmologist notes pallor of the optic disc and visual field defects consistent with glaucomatous optic atrophy. The diagnosis is confirmed through optical coherence tomography (OCT) showing thinning of the retinal nerve fiber layer., A patient with angle-closure glaucoma experiences a sudden increase in intraocular pressure, leading to ischemic damage to the optic nerve in their left eye.Following treatment to lower the pressure, the patient develops glaucomatous optic atrophy, resulting in permanent visual impairment., A patient with a history of traumatic eye injury develops secondary glaucoma in their left eye.Over time, the elevated intraocular pressure causes damage to the optic nerve, leading to the development of glaucomatous optic atrophy and subsequent vision loss.

Documentation should include detailed ophthalmological examination findings, such as visual acuity, visual field testing, and appearance of the optic disc.Imaging studies like OCT may be included to confirm optic nerve damage. A history of glaucoma and any associated treatments should also be documented.
