Secondary corneal edema, right eye

This code signifies swelling of the cornea in the right eye that is a consequence of another underlying ocular or systemic condition. This edema results from fluid accumulation within the corneal layers, often leading to blurred vision and discomfort. It is not a primary condition but rather a manifestation of another disease process.

Use this code when documentation clearly indicates corneal edema in the right eye that is secondary to a specific cause, such as post-surgical complications, inflammation (e.g., uveitis), or elevated intraocular pressure (e.g., glaucoma). The physician's notes should explicitly state "secondary corneal edema" or describe edema in the context of another primary diagnosis affecting the right eye.

• Always code the underlying primary condition causing the corneal edema first, followed by this code.
• Distinguish carefully between primary corneal edema (e.g., Fuchs' endothelial dystrophy) and secondary edema; this code is only for secondary causes.
• Ensure laterality is correctly documented and coded; this code specifies the right eye.
