Traumatic rupture of right ear drum, subsequent encounter

This code signifies a traumatic perforation of the right tympanic membrane that is being treated or evaluated after the initial injury. It indicates that the patient is in the healing phase following an acute event, such as a direct blow, barotrauma, or foreign body insertion.

Apply this code for follow-up visits, medication refills, or ongoing management of a previously diagnosed traumatic right ear drum rupture. Documentation should clearly state "subsequent encounter," "follow-up," or describe treatment after the initial injury has occurred.

• Ensure laterality is correctly documented as "right ear."
• Distinguish from initial encounter (S09.21XA) and sequela (S09.21XS).
• Confirm the rupture is traumatic in nature; non-traumatic perforations (e.g., otitis media) use different codes.
