Unspecified retinoschisis, bilateral

This code signifies a condition where the retina splits into two layers, affecting both eyes, without further specification of the type or cause of the retinoschisis. This separation can lead to visual field defects and, in some cases, retinal detachment.

Use this code when documentation indicates retinoschisis is present in both eyes, but the specific type (e.g., degenerative, congenital, or secondary) is not documented by the provider. This code is appropriate when the medical record explicitly states "bilateral retinoschisis" without further detail.

• Do not use if the type of retinoschisis (e.g., degenerative, congenital) is specified; instead, use a more specific code from the H33.1 subcategory.
• Ensure documentation clearly indicates involvement of both eyes; otherwise, use a code for unilateral involvement (H33.11- or H33.12-).
• Always query the provider for clarification on the type of retinoschisis if not documented, to allow for more specific coding.
