1What Is the A604 OHIP Code?
A604 is designated for medical specific re-assessments in cardiology. This code is typically used in office or outpatient settings to manage and follow up on defined cardiac issues. For instance, it may be used when assessing a patient's response to adjusted heart failure or antihypertensive treatments, or when reviewing a repeat ECG.
A604 plays a critical role in ensuring that cardiologists can provide targeted follow-up without overbilling for full assessments. Missed opportunities for billing this code often arise from unclear distinctions between initial assessments and specific re-assessments, leading to potential underbilling.

3Eligibility Requirements
Eligibility for billing A604 is defined by the General Preamble of the OHIP Schedule of Benefits. The re-assessment requires documentation of a focused history and examination pertinent to the specific cardiac issue at hand. If the service is provided virtually, it should be billed as A604A.
Importantly, the physician must duly record the start and end times of the consultation on the patient's permanent medical record. The service may be provided more than once if the necessity is documented, but it's crucial to adhere to guidelines on assessment intervals appropriate for follow-up care.
4What Your Clinical Note Must Show
Ensure the following are recorded to comply with OHIP requirements:
- Comprehensive history focused on the specific cardiac issue.
- Relevant examination findings.
- Start and end times of the session.
- Rationale for re-assessment documented.
5Weak vs. Strong Note Examples
The strong note succeeds by documenting specific history and examination details, aligning with cardiac issues addressed. The weak note lacks detailed observations and fails to establish a timeline.
Followed up on hypertension. All is well. Advised to continue medication.
Reviewed patient's response to adjusted antihypertensive regimen.
Collected detailed history of symptoms and side effects.
Performed cardiovascular examination focusing on specific concerns.
Discussed next steps based on current response and ECG findings.
