1What Is the A034 OHIP Code?

The A034 billing code under OHIP is used for claiming partial assessments, applicable predominantly in general surgery for brief evaluations of specific patient issues. Typical scenarios involve quick post-operative office visits for wound checks or interval assessments of conditions like hernias.

A partial assessment involves taking a history of the presenting complaint, performing a necessary physical examination, giving advice to the patient, and maintaining appropriate records. Despite its limited scope, it provides essential follow-up care post-surgery, ensuring patient recovery is on track, and any complications are promptly addressed.

This code is often missed within practices due to misunderstanding the time documentation requirements or the specific nature of partial versus complete assessments, leading to potential underbilling.

3Eligibility Requirements

A034 is eligible for billing when performing a limited service that includes taking a history of the presenting complaint, conducting the necessary physical examination, offering medical advice, and documenting the consultation appropriately.

According to the OHIP guidelines, the date and duration of service must be recorded, noting the start and end times on the patient's medical record.

It is critical to note that a partial assessment cannot be claimed alongside a major pre-operative visit unless it is justified as the latter, as defined in the General Preamble.

Virtual delivery of partial assessments is allowed under 'VIDEO OR TELEPHONE' billing as A034A. However, ensure documentation captures the method of delivery.

4What Your Clinical Note Must Show

1Time Recording

The service duration must be documented.

  • Record the start and end time of the assessment.
  • Ensure times are logged in the patient’s chart.
2Partial Assessment Content

Each assessment must include four key components:

  • History of the presenting complaint.
  • Necessary physical examination.
  • Advice given to the patient.
  • Appropriate records of the service.

5Weak vs. Strong Note Examples

The strong note succeeds in detailing the specific complaint, examination findings, advice, and ensures all required documentation elements, including time, are covered. The weak note lacks sufficient detail and fails to capture necessary documentation or advice content.

Weak Note

Assessed patient post-surgery. Wound looks fine. End.

Strong Note

Conducted partial assessment on post-operative day 7. Patient reports mild discomfort in the operative area. Examination reveals minor erythema without drainage.

Advice given on maintaining wound hygiene and monitoring for any increase in redness or discharge. Follow-up scheduled in one week if symptoms persist.

  • Duration: 10:00 AM - 10:15 AM.
  • Documented all critical encounters and advice.
