Peripheral pterygium, stationary, unspecified eye

This code describes a non-progressive, benign growth of conjunctival tissue that extends onto the cornea, originating from the peripheral aspect of the eye. It indicates that the pterygium is stable and not actively growing or causing significant visual impairment. The "unspecified eye" modifier means the laterality of the condition is not documented.

Use this code when documentation confirms a pterygium that is noted as "stationary," "stable," or "non-progressive," and there is no indication of active inflammation, growth, or vision compromise. This code is appropriate when the medical record does not specify whether the condition affects the right or left eye.

• Only use this code when laterality is truly unspecified; otherwise, use the more specific codes for right (H11.041) or left (H11.042) eye.
• Do not use this code if the pterygium is inflamed (H11.03-) or actively growing (H11.02-).
• Ensure documentation clearly states the stationary nature of the pterygium to differentiate it from other types.
