Device problem

A fictional adult has a documented problem involving a lead of an implanted cardiac device. The operative plan concerns lead repair. The record identifies the existing generator and does not state that it is being replaced with a new unit.

Operative work

The clinician opens the device pocket, temporarily removes the generator as needed to access the lead, repairs the lead and returns the original generator. The device identity before and after the procedure is the same.

Component record

The operative inventory confirms that no new generator is implanted. The report’s words removal and reinsertion describe handling the original device during the repair. They do not establish replacement with another generator.

Reporting proposal

A preliminary claim separately lists generator removal, generator insertion and lead repair. The learner must investigate the included lead-repair components under the cited NCCI rule and choose the actual service rather than treating each verb as an independent procedure.

Your coding worksheet

Identify the component repaired.
Verify whether the generator is original or new.
Evaluate the separate generator lines.
Explain what changed fact would require a replacement review.

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 documented procedure repairs a lead.
The same generator is reinserted; no new generator is supplied.
NCCI includes the described handling of the original device within the typical lead-repair relationship.
A genuinely new replacement device would require a different entry and combination review; it cannot be inferred from temporary removal.
