1What Is the C624 OHIP Code?
C624 is an OHIP billing code used when a physician provides a re-assessment for an in-patient in the specialty of clinical immunology and allergy. This typically occurs after an initial consultation, when follow-up evaluation is necessary, such as observing changes following the cessation of a suspected allergen.
The re-assessment focuses on reviewing and potentially revising treatment plans based on the patient's response, making it an essential part of allergy and immunology management. It's commonly used to monitor the resolution of symptoms like rashes or other allergic reactions, often following medication changes.
Physicians may overlook this billing opportunity due to misinterpretation of re-assessment conditions or failure to document time accurately. It's critical to ensure precise documentation to maximize billing efficiency.

3Eligibility Requirements
C624 can be billed for medical specific re-assessments conducted on hospital in-patients in the field of clinical immunology and allergy. It is eligible for virtual delivery but only through video communication, not via telephone.
Physicians must adhere to the General Preamble GP21 requirements, ensuring a comprehensive history and examination are performed, excluding areas that are not medically required or declined by the patient. Additionally, accurate time recording from start to end of the service is mandatory to ensure payment eligibility, as outlined in GP7.
4What Your Clinical Note Must Show
Ensure you include the following in the medical records:
- Complete history including presenting complaint, family, past medical, social histories, and functional inquiry.
- Physical examination as required, excluding examinations the patient declined or are not medically necessary.
- Record the start and end times of the assessment accurately.
5Weak vs. Strong Note Examples
The strong note succeeds because it provides detailed medical history, examination findings, and accurately records the time duration, ensuring compliance and supporting the need for re-assessment. The weak note lacks specificity and required documentation elements, risking reimbursement issues.
Patient seen for follow-up, improvement noted. End.
No specific documentation of time or detailed examination findings.
Patient re-assessed for rash following medication modification.
Complete history reviewed: No new complaints; rash improving.
Examination focused on skin with no new findings.
Time of service: 10:00 AM to 10:30 AM.
- Included detailed history and examination results.
- Accurate time documentation provides clear service duration.
- Specific clinical context justifying the re-assessment.
