1What Is the H131 OHIP Code?

H131 is an OHIP billing code used by emergency department physicians to document a minor assessment. This service includes a brief history and examination or provides brief advice regarding health maintenance, diagnosis, treatment, and/or prognosis.

Typically, this code is applied to simple cases presented on weekday evenings, reflecting quick evaluations of single problems. It's crucial in efficiently managing patient flow during busy hours while ensuring necessary care.

Physicians often miss billing opportunities with H131 due to overlooking time recording or misunderstanding service scope. Ensuring clear, concise chart notes can help capture eligible services under this code.

3Eligibility Requirements

The H131 billing code applies to minor assessments conducted specifically from Monday to Thursday between the hours of 17:00 and 24:00. It is essential to adhere to the General Preamble GP27, which defines a minor assessment as encompassing a brief history and examination of the affected part or region, or brief advice regarding health concerns.

To successfully claim H131, documentation must include accurate time records of when the service started and ended, as per General Preamble GP7. Failure to document these details renders the service non-payable.

4What Your Clinical Note Must Show

1Documentation for Minor Assessment

Ensure the time of service is carefully documented as this is crucial for claim acceptance.

  • Start and End Time must be recorded in the patient's medical record
  • Ensure charting includes brief history of affected region or related advice
  • Maintain a clear medical record of examination findings or advice given

5Weak vs. Strong Note Examples

The strong note is successful because it precisely documents the patient's concern, the examination performed, the advice given, and crucially, records start and end times for the service. The weak note inadequately captures these elements.

Weak Note

Patient seen for a quick check-up. Prescribed medication.

Strong Note

Patient presented with headache and slight dizziness.

Completed a brief neurologic exam; discussed hydration importance.

  • Service began at 18:05 and ended at 18:15
  • Brief history recorded, examination performed
  • Advised on hydration and monitored for 10 minutes post-advice
