Chalazion right eye, unspecified eyelid

This code signifies a chalazion affecting the right eye, where the specific eyelid (upper or lower) is not documented. A chalazion is a chronic, sterile lipogranulomatous inflammation of a meibomian gland, typically presenting as a painless, firm nodule.

Apply this code when documentation clearly states a chalazion is present in the right eye, but the physician does not specify whether it is on the upper or lower eyelid. This is appropriate for initial diagnoses or follow-up visits where the exact eyelid location remains unclarified.

• Ensure documentation specifies "right eye" and "unspecified eyelid" to accurately use this code.
• Avoid using this code if the documentation specifies the upper (H00.11) or lower (H00.12) eyelid of the right eye.
• Do not confuse with hordeolum (stye), which is an acute bacterial infection of an eyelid gland.
