ICD-10 Code H27.139 – Posterior dislocation of lens, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.139 – Posterior dislocation of lens, unspecified eye
What it is
This code identifies a lens that has moved backward from its normal position in the eye, with no eye laterality specified. Use it when the record documents posterior dislocation of the lens and does not identify right or left eye.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include blurred vision, monocular diplopia, or an abnormal lens position on eye examination or imaging.
When to use this code
Use H27.139 when the provider documents posterior dislocation of the crystalline lens and laterality is not stated. It also fits cases where the lens has displaced into the vitreous or posterior segment, if that is the documented diagnosis. Check documentation if the note only says lens subluxation or another lens disorder.
Do not use for
Do not use this code for anterior lens dislocation, lens subluxation without dislocation, or traumatic eye injury when the documented diagnosis is different. Check documentation when the eye side is specified or when another ocular disorder better explains the finding.
Coding tip
If laterality appears elsewhere in the chart, verify whether a more specific code is supported before assigning the unspecified-eye code.
