The original generator moves to another pocket

Read an original fictional chart, identify the supported facts, and explain your coding workflow.

Service date: 2026-09-09 · Professional operative service; cited Medicare NCCI relationship

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

Device concern

Fictional adult with a spinal neurostimulator has a physician-documented problem with the current generator pocket. The planned work is relocation of the generator. The record identifies the existing device and does not describe replacement of the electrode array.

Operative sequence

The surgeon opens the original pocket, removes the existing generator temporarily and prepares a new pocket. The same generator is placed in the new pocket and connected as documented. The operative inventory confirms that no new generator or receiver is implanted.

Identity check

The device identifier before and after the operation is unchanged. The report’s words removal and insertion refer to handling and relocating the original device. They do not establish a replacement generator simply because the pocket location changes.

Charge review

The draft selects the new-generator replacement pathway and adds a removal line. Compare that proposal with NCCI’s distinction between revision or relocation and replacement. The learner must use the original device’s identity, the actual work and the current complete entry.

Your coding worksheet

  1. Identify the device that remains after surgery.
  2. Determine whether a new generator is documented.
  3. Choose the relationship to investigate before exact coding.
  4. Evaluate the proposed replacement and extra removal.

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

Write your answer

Use only this fictional record. Your entries stay on this page and disappear when you leave or reload. Do not enter real patient information.

Compare with the worked explanation
  1. The original generator remains in use in a different pocket.
  2. No new generator is implanted.
  3. NCCI C.16 directs review of the revision relationship rather than the replacement pathway requiring a new device.
  4. The two verbs do not justify the proposed replacement plus removal; review the full entry for the actual relocation work.
