ICD-10 Code H44.522 – Atrophy of globe, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.522 – Atrophy of globe, left eye
What it is
H44.522 identifies atrophy of the left eye globe, meaning the eyeball has shrunk or wasted away. It describes a structural end-stage change rather than a cause, so you should code the underlying condition when documented.
Clinical signs
Typical findings include a visibly smaller, shrunken left globe and reduced ocular volume. Vision is often severely impaired or absent; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents atrophy of the left globe, including phthisical or markedly shrunken eye findings. It is appropriate when the left eye is specifically identified and the record supports a chronic atrophic change. If the cause is stated, sequence or add the underlying diagnosis as directed.
Do not use for
Do not use this code for temporary eye swelling, trauma without atrophy, or unspecified eye laterality. Check documentation if the record only says “eye disorder” or “vision loss” without globe atrophy.
Coding tip
Verify laterality carefully; H44.522 is for the left eye only.
