1What Is the A484 OHIP Code?
A484 is an OHIP billing code used for medical specific re-assessments performed by rheumatologists. This service includes a comprehensive history taking and physical examination of one or more systems, particularly focused on joint or connective tissue issues.
Re-assessments are typically conducted to evaluate a rheumatologic patient's response to treatment modifications, such as the response to a new medication for inflammatory arthritis or urate-lowering therapy for gout. While commonly billed by rheumatologists, it may be missed if not all criteria, like thorough history and examination, are well-documented.
Due to frequency limitations, it's crucial for physicians to track the number of specific re-assessments billed per patient, per year, to ensure compliance with OHIP's regulations.

4What Your Clinical Note Must Show
To bill A484, maintain comprehensive records fulfilling the following:
- Record a full relevant history and examination of the affected systems.
- Ensure the start and end times of the assessment are noted in the patient's chart.
- Review notes discerning any decision points or changes in management following the assessment.
5Weak vs. Strong Note Examples
The strong note is successful because it provides a detailed account of the patient's progress, specific treatment response, and document the duration of the assessment. The weak note lacks specificity and critical details required for compliance.
