Department reconciliation record

Original fictional medical-direction worksheet for September 9, 2026. Dr. Ellis is the attending anesthesiologist named on three completed outpatient anesthesia records. Each case has a qualified CRNA identified on its own record. The coder is reconciling the morning log before completing the physician’s Medicare role review. There are no other cases involving Dr. Ellis during the intervals supplied here.

Case A

A 74-year-old Original Medicare patient undergoes a scheduled right-eye cataract procedure with monitored anesthesia care. The signed anesthesia log begins at 08:00 and ends at 09:00. The separate record contains the patient’s assessment and care plan; this summary has not yet reconciled all attending participation entries.

Case B

A 59-year-old patient with commercial insurance undergoes a scheduled hernia repair. The signed anesthesia log runs from 08:20 to 09:20. The case is assigned to the same attending anesthesiologist. Its non-Medicare payer is shown on the reconciliation sheet, along with its actual care interval.

Case C

A 70-year-old Original Medicare patient undergoes a scheduled knee procedure. The signed anesthesia log runs from 10:00 to 11:00. The two earlier records have already ended. No interval from this case overlaps the earlier cases.

Documentation work queue

One draft summary treats all three cases as concurrent because they share the date. Another deletes Case B from the count because it is not a Medicare claim. Correct the timeline before assessing the full direction requirements. The reviewer still must reconcile the physician’s assessment, plan, demanding-procedure participation, monitoring, availability and indicated postoperative-care evidence from the individual records.

Your coding worksheet

Draw the three intervals on one timeline.
Identify the exact overlap.
Explain whether Case B can be ignored for concurrency.
Separate timing evidence from the complete medical-direction conclusion.

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

A and B overlap from 08:20 to 09:00; C begins after both end.
The maximum overlap shown is two cases, not all three cases on the date.
The non-Medicare case is not excluded from the cited concurrency calculation solely because of payer.
These intervals support a timing conclusion only. Verify all medical-direction conditions before the final role modifier and claim decision.
