1What Is the A613 OHIP Code?

What is A613?

The A613 billing code is a medical specific assessment code used by hematologists in Ontario, Canada, facilitated under the OHIP system. This code is designed for comprehensive evaluations in an office or outpatient clinic setting.

It involves a complete history and a detailed examination specifically directed at the hematological system. It's commonly used when a patient is referred with issues such as a single abnormal blood count or index, or after experiencing their first thrombotic event.

The comprehensive nature of A613 makes it easy to miss due to the detailed requirements needed to qualify. Physicians must ensure that they perform the full extent of the assessment, documenting all findings, in order to bill this code correctly.

3Eligibility Requirements

Eligibility Requirements

According to the OHIP Schedule of Benefits, the A613 code is used by hematologists for specific medical assessments conducted outside a patient's home. Special conditions apply:

Frequency Limit

  • Once per patient per 12 months per physician. However, this limit increases to two conditions:
    1. The patient presents with a different, unrelated diagnosis.
    2. At least 90 days have elapsed since the last assessment and the second one is a hospital admission assessment.

Time Recording

  • Physicians must record the start and end times of the assessment on the patient's permanent medical record, as payment will not be processed without it.

Virtual Delivery

  • A613 can also be administered virtually, using code A613A.

4What Your Clinical Note Must Show

1Patient Medical Record Documentation

To ensure compliance and avoid payment issues, the following must be documented:

  • Complete history and detailed examination findings
  • Start and end times of the assessment
  • Diagnosis or clinical justification for the assessment

5Weak vs. Strong Note Examples

The strong note provides a comprehensive documentation of both the clinical findings and the physician's rationale for the assessment, whereas the weak note lacks detail and specificity.

Weak Note

Patient presented with fatigue. Blood test ordered. Advised follow-up.

Strong Note

Patient presents with persistent fatigue and a history of anemia. Complete blood count shows low hemoglobin and elevated white cell count. Conducted a comprehensive examination of the hematological system.

  • Conducted detailed blood count evaluation.
  • Discussed potential differential diagnoses including iron deficiency anemia and leukocytosis.
  • Plan for follow-up includes additional testing and review of hematology panel in 4 weeks.
