Central corneal opacity, left eye

This code signifies a non-transparent area located in the central part of the cornea of the left eye. This opacity can result from various causes, including trauma, infection, inflammation, or degenerative conditions, leading to impaired vision.

Apply this code when documentation specifies a central corneal opacity affecting the left eye. This diagnosis is supported by ophthalmological examination findings, such as slit-lamp biomicroscopy, noting the location and laterality of the opacity.

• Ensure the documentation clearly specifies "central" and "left eye" to accurately assign this code.
• Differentiate from peripheral corneal opacities or opacities affecting other parts of the eye.
• Consider coding an underlying cause (e.g., corneal scar, keratitis) if documented, as this code describes the manifestation.
