Pannus (corneal), unspecified eye

This code describes the presence of pannus, which is an abnormal growth of fibrovascular tissue onto the cornea, originating from the limbus. This condition can lead to corneal opacification and vision impairment. This specific code indicates that the affected eye is not specified in the medical record.

Use this code when documentation clearly indicates the presence of corneal pannus but does not specify whether it affects the right, left, or both eyes. This code is appropriate when the physician's assessment identifies pannus without laterality. Documentation should include a diagnosis of pannus without further specification of the affected eye.

• Avoid using this code if laterality (right, left, or bilateral) is documented; instead, select the more specific code.
• Ensure the medical record explicitly states "unspecified eye" or lacks any laterality information for pannus.
• Consider querying the provider if laterality is unclear to allow for more precise coding.
