ICD-10 Code H53.022 – Refractive amblyopia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.022 – Refractive amblyopia, left eye
What it is
H53.022 identifies amblyopia in the left eye caused by unequal or uncorrected refractive error. The brain relies more on the better-seeing eye, leading to reduced vision in the left eye.
Clinical signs
Typical findings include decreased visual acuity in the left eye that is not fully explained by structural eye disease. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents refractive amblyopia specifically affecting the left eye. It is appropriate when reduced vision results from refractive error and the laterality is clearly stated. Check documentation if the cause or eye is not specified.
Do not use for
Do not use this code for amblyopia in the right eye, bilateral amblyopia, or unspecified amblyopia. Do not assign it when decreased vision is due to another eye disorder rather than refractive amblyopia.
Coding tip
Always verify laterality in the note; H53.022 is only for the left eye.
