ICD-10-CM Billable Code

H40.122

Low-tension glaucoma, left eye

Clinical Classification Guidelines

Medical Intelligence & Overview

Low-tension glaucoma is a type of glaucoma where optic nerve damage occurs even though the eye pressure remains within normal ranges. Specifically affecting the left eye in cases classified under ICD-10 code H40.122, this condition can lead to gradual vision loss if not detected and managed early. Unlike other types of glaucoma, where high eye pressure is a primary concern, low-tension glaucoma presents unique challenges in diagnosis and treatment. Understanding its causes, symptoms, and potential management options is crucial for preserving vision.

Causes & Symptoms

Clinical Causes: Abnormal blood flow to the optic nerve Increased sensitivity of the optic nerve to normal eye pressures Family history of glaucoma or optic nerve damage Underlying health conditions such as vascular dysregulation or hypotension Genetic predisposition influencing nerve susceptibility

Key Symptoms: Gradual loss of peripheral (side) vision Difficulty noticing objects in the peripheral field Blurring or narrowing of the visual field over time Often no noticeable pain or symptoms in early stages Potential for asymptomatic progression leading to significant vision impairment

Diagnostic & Treatment

Diagnosis Path: Measuring intraocular pressure to confirm normal eye pressure levels Visual field tests to detect peripheral vision loss Optic nerve evaluation through ophthalmoscopy or imaging techniques Assessment of the optic nerve head and nerve fiber layer Evaluation of blood flow and optic nerve health when necessary

Treatment Protocols: Medications such as eye drops to improve blood flow or reduce stress on the optic nerve Laser therapy procedures if deemed appropriate by a healthcare provider Surgical interventions in advanced cases to enhance drainage or nerve health Managing underlying health conditions that may affect blood flow Regular monitoring to track disease progression and adjust treatments accordingly

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
