ICD-10 Code H53.15 – Visual distortions of shape and size (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.15 – Visual distortions of shape and size
What it is
H53.15 identifies a disturbance in visual perception where objects appear altered in shape or size. You use it when the record describes distorted vision, such as things looking larger, smaller, stretched, or otherwise misshapen.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe metamorphopsia, micropsia, macropsia, or other perceived changes in object size or form, often reported by the patient during visual complaints.
When to use this code
Use this code when the provider documents visual distortion of shape or size as the diagnosis or symptom being evaluated. It fits encounters where the complaint is clearly perceptual rather than reduced acuity or field loss.
Code it when the chart states distorted images, warped lines, or objects appearing unusually large or small. If the documentation only says “vision changes,” check documentation before assigning H53.15.
Do not use for
Do not use this code for blurry vision, diplopia, or visual field defects unless shape or size distortion is specifically documented. Check documentation if the symptom is part of a broader eye disorder.
Coding tip
Assign H53.15 only when the provider explicitly documents distortion of shape or size; otherwise, select the more specific documented visual symptom.
