1What Is the C484 OHIP Code?
The C484 OHIP billing code allows rheumatologists to claim for a medical specific re-assessment within a non-emergency hospital in-patient setting. This involves reviewing a patient, especially following a treatment alteration or when determining between joint infection and inflammatory processes. The code is generally used after changes in steroid dosage or upon returning synovial fluid results, making it essential for precise diagnoses and effective management of complex rheumatologic conditions.
Rheumatologists frequently rely on C484 to ensure continuity of care by reassessing patients with evolving conditions. Despite its importance, this code is sometimes overlooked because physicians may not record the reassessment duration comprehensively, impacting claim approval. Furthermore, unfamiliarity with the billing frequency limit may also lead to missed claims.

3Eligibility Requirements
C484 is applicable for non-emergency hospital in-patient services specifically within the Rheumatology specialty and can be provided virtually through video, but not via telephone. Each physician is restricted to billing this code two times per patient within a consecutive 12-month period, barring instances related to hospital admissions. It emphasizes a complete history and physical examination relevant to one or more systems.
Virtual delivery eligibility highlights the growing acceptance and necessity of remote consultations, particularly applicable when physical attendance might be challenging. However, physicians must ensure that the timing of the service is accurately recorded in the patient's medical record, detailing when the service began and ended, as the service is non-payable without this documentation.
4What Your Clinical Note Must Show
Ensure thorough documentation of every stage of the re-assessment.
- Record the start and end times of the service on the patient's chart.
- Ensure comprehensive notes on the patient's history and physical examination details.
- Include decision-making rationale for any change in treatment.
5Weak vs. Strong Note Examples
The strong note is successful due to detailed examination findings, rationale for treatment decisions, and precise time documentation, which the weak note lacks.
Reviewed patient. Condition stable.
Re-assessed patient due to changes in steroid dosage. Examined joints for signs of inflammation. Noted improvement in range of motion.
- Recorded start and end times: 10:00 AM - 10:45 AM.
- Documented synovial fluid analysis results.
- Noted decision to continue current steroid regimen.
