Chorioretinal scars after surgery for detachment, unsp eye

This code signifies the presence of scar tissue in the choroid and retina that developed as a complication following surgical repair of a retinal detachment. These scars are a sequela of the previous surgery and can impact visual acuity or field. The specific eye affected is not documented or is unknown.

Use this code when documentation indicates chorioretinal scarring as a post-procedural complication of retinal detachment surgery, and the laterality of the affected eye is not specified. This code is appropriate for follow-up encounters where the scar is being monitored or is causing ongoing symptoms. The medical record should clearly state "post-surgical chorioretinal scar" or similar phrasing.

• Do not use this code if the laterality (right or left eye) is documented; instead, use the more specific codes for right (H59.811) or left (H59.812) eye.
• This code is for scars after surgery, not for active retinal detachment or other post-operative complications.
• Sequence this code after the primary reason for the encounter if the scar is being managed or evaluated.
