ICD-10 Code H27.133 – Posterior dislocation of lens, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.133 – Posterior dislocation of lens, bilateral
What it is
This code identifies complete displacement of the crystalline lens backward in both eyes. It means the lenses are no longer in their normal position and have moved into the vitreous or posterior segment.
Clinical signs
Findings may include reduced vision, monocular diplopia, or an abnormal lens position on exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when documentation clearly states posterior dislocation of the lens in both eyes. It is appropriate for traumatic, spontaneous, or disease-related lens displacement if the provider specifies bilateral involvement. If the record only mentions lens subluxation or one eye, check documentation.
Do not use for
Do not use this code for unilateral lens dislocation, lens subluxation, or cataract without dislocation. If the note does not confirm posterior displacement in both eyes, check documentation.
Coding tip
Code only when the provider documents bilateral posterior lens dislocation, and verify laterality carefully before assigning H27.133.
