H27.13 Posterior dislocation of lens

ICD-10-CM Code H27.13: Posterior Dislocation of Lens

ICD-10-CM code H27.13 identifies a posterior dislocation of the lens, classified as an anatomical abnormality or disease. This active diagnosis code is a child of H27.1 and lacks narrower subcodes. Multiple terminology and ontology databases map this concept to H27.13, and the coding tree includes specific laterality options. 1 3 4

Plain-language overview

ICD-10-CM code H27.13 identifies a posterior dislocation of the lens, which terminology sources classify as an anatomical abnormality or a disease and syndrome. 1

What this code represents

The diagnosis code H27.13 represents a posterior dislocation of the lens and is an active concept in the ICD-10-CM version 2026 terminology system with no narrower subordinate concepts. 1

Within the ICD-10-CM hierarchy, H27.13 is a direct child code falling under the parent category H27.1, which broadly encompasses dislocations of the lens. 1

Coding details

Although H27.13 is a valid code, the coding tree includes more specific laterality options for this condition, such as H27.131 for the right eye and H27.132 for the left eye. 3

Additional specific variations in the coding tree include H27.133 for a bilateral posterior lens dislocation and H27.139 when the affected eye is unspecified. 3

Documentation considerations

The ICD-10-CM coding tree lists distinct posterior lens dislocation variations for the right eye, left eye, bilateral cases, and unspecified eye presentations. 3

What the sources add

While one official terminology record establishes the code's active status and parent hierarchy, a separate clinical coding tree details the specific laterality subcodes available within the classification. 1 3

Multiple distinct terminology and ontology databases map the exact same concept of posterior lens dislocation to the ICD-10-CM code H27.13, alongside historical and alternative clinical identifiers. 2 4
