ICD-10 Code H53.72 – Impaired contrast sensitivity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.72 – Impaired contrast sensitivity
What it is
Impaired contrast sensitivity means reduced ability to distinguish an object from its background when brightness differences are subtle. You use this code when the record specifically documents contrast sensitivity loss.
Clinical signs
Patients may report difficulty seeing in dim light, glare, fog, or low-contrast settings such as gray text on a light background. Clinical features vary; refer to documentation.
When to use this code
Use H53.72 when the clinician documents impaired contrast sensitivity as the diagnosis or a confirmed finding. It may appear in ophthalmology or neuro-ophthalmology notes, vision testing reports, or follow-up assessments. Code it when the issue is stated clearly, not inferred from general blurry vision.
Do not use for
Do not use this code for unspecified visual disturbance, refractive error, or general decreased visual acuity unless contrast sensitivity loss is specifically documented. Check documentation if the note describes only poor vision or glare symptoms.
Coding tip
Assign H53.72 only when the provider names contrast sensitivity impairment or records testing that supports it.
