Use your code books and write your reasoning before opening the walkthrough. This exercise contains no real patient information.
Planned operation
Synthetic adult undergoes planned left-eye cataract extraction by phacoemulsification with lens implantation. A clear-corneal incision provides surgical access. The patient has no traumatic corneal injury at this encounter.
Operative course
The surgeon removes the cataract and inserts the lens through the planned opening. A suture closes that same incision at the end of the operation. No separate wound or additional injury repair is documented.
Record distinction
The note uses the word repair in its closure paragraph, but the opening was created surgically during the same encounter. The terminology must be read in context. It does not establish a separate accidental laceration or a second operative encounter.
Claim audit
The proposed claim adds a traumatic corneal laceration-repair procedure to the main operation. Evaluate the proposal using the origin of the wound and NCCI’s surgical-incision rule. Keep the closure details in the clinical record even when the work is included.
Your coding worksheet
- Identify how the corneal opening arose.
- Determine whether a separate traumatic wound is supplied.
- Evaluate the laceration-repair proposal.
- Explain why the verb repair is insufficient alone.
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 opening is the incision made for the planned operation.
- No independent traumatic corneal wound is documented.
- NCCI D.16–18 includes closure of the surgical incision and does not support recoding it as an additional traumatic repair.
- The operative context determines the relationship; a closure verb does not create a new injury.
