Use your code books and write your reasoning before opening the walkthrough. This exercise contains no real patient information.

Clinical setting

Fictional patient undergoes a documented left tympanostomy procedure for a clinician-established middle-ear condition. The operative report identifies the left ear and intended tube placement. This exercise addresses the component opening rather than anesthetic selection or the complete final entry.

Procedure sequence

The clinician makes the tympanic-membrane opening needed for the tympanostomy and places the tube as documented. The opening and placement occur during the same procedure. No separate operation on the right ear is supplied.

Completion record

The report preserves both the myringotomy step and tube placement. The two names describe parts of the completed left-ear service, not proof of two independent encounters. The tube remains as intended at the end of the procedure.

Coding issue

A draft lists myringotomy in addition to the tympanostomy solely because both are named in the operative note. Apply NCCI’s inclusion, then inspect the authorized complete entry and any required anesthetic or laterality facts. Do not infer missing facts from the patient’s age.

Your coding worksheet

Identify the side and completed service.
Explain the role of the membrane opening.
Evaluate the separate myringotomy line.
List the remaining facts required for full-entry selection.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Compare with the worked explanation

The completed procedure is the documented left tympanostomy with tube placement.
The myringotomy creates the opening needed for that procedure.
NCCI E.2 includes the myringotomy in the tympanostomy relationship.
Verify the full current entry and actual anesthetic and laterality documentation; do not invent them from a general procedure label.
