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

Outpatient procedure

Fictional adult receives a planned outpatient procedure with routine cardiac rhythm monitoring. The monitor continuously displays the rhythm as part of procedural observation. This case supplies no independent diagnostic rhythm-study order or separate diagnostic encounter.

Recorded tracing

Staff print a strip to document the monitored rhythm in the procedure record. The printout has a timestamp and patient identifier. It is not accompanied by a separately performed diagnostic rhythm examination or a report establishing another study.

Proposed charge

A draft adds a diagnostic rhythm ECG service solely because the strip was printed and retained. The person preparing the charge does not identify another diagnostic purpose or performed examination beyond routine monitoring.

Review scope

Determine whether stored monitoring data establish the proposed diagnostic procedure. The question is about the purpose and completed work, not whether cardiac monitoring was clinically appropriate. Do not create a diagnostic examination from a printed artifact alone.

Your coding worksheet

Identify why the rhythm was recorded.
Distinguish monitoring from a diagnostic study.
Evaluate the extra diagnostic line.
State what facts are absent.

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 rhythm was recorded for routine procedural monitoring.
No independent diagnostic study is documented.
NCCI I.12 prohibits using diagnostic rhythm ECG entries for that monitoring.
A distinct diagnostic purpose and completed reportable study cannot be inferred from the printout.
