1What Is the C325 OHIP Code?
A limited consultation (C325) in the context of medical genetics involves providing a concise assessment during a hospital in-patient stay, aimed at determining the need for genetic testing or further genetic investigation without conducting a comprehensive pedigree analysis or extended counseling. Because these consultations are less demanding and require less time compared to full consultations, they are ideal for straightforward cases that need a quick genetic opinion.
Proper use of C325 ensures that patients receive timely and relevant genetic insights, helping the attending medical team make informed decisions during the hospital stay. However, billing C325 can sometimes be missed due to inadequate documentation or misunderstanding the referral requirement criteria, emphasizing the need for physicians to familiarize themselves with the consultation and documentation standards.
2Related Codes
| Code | Name | Frequency | Description |
|---|---|---|---|
| A220 | Special genetic consultation | Varies | Consultation involving detailed genetic assessment and management planning. |
| A223 | Extended special genetic consultation | Varies | Comprehensive genetic consultation services for complex cases. |
| A225 | Consultation | Varies | Standard genetic consultation for detailed case review. |
| A226 | Repeat consultation | As medically necessary after initial consultation | Follow-up genetic consultation to review patient progress or additional findings. |
3Eligibility Requirements
C325 is eligible for non-emergency hospital in-patient settings within the specialty of Medical Genetics and Genomics. The service must be rendered following a written referral from a physician, nurse practitioner, or dental surgeon requesting expertise due to the complexity, seriousness, or obscurity of the case. This code can be billed once per two consecutive twelve-month periods for the same patient, physician, and diagnosis. If the consultation involves a different, clearly unrelated diagnosis, the service can be billed once every twelve months. Additionally, C325 can be billed for virtual consultations if delivered via video, with virtual services billed as C325A. Telephone delivery is not eligible for virtual billing under this code.
The consultation must meet the Ontario Health Insurance Plan's outlined requirements, including written justification, and cannot overlap with a full consultation or constitute repetitive services not warranted by the patient's condition.
4What Your Clinical Note Must Show
Ensure the consultation is based on a properly documented written request from a qualified referrer.
- Referring physician, nurse practitioner, or dental surgeon information.
- Clear indication of the complexity or obscurity requiring consultation.
Document the consultation detailing the assessment provided and any recommendations made.
- Initial patient presentation.
- Brief note on genetics-related findings or lack thereof affecting management.
5Weak vs. Strong Note Examples
The strong note provides detailed explanation of the consultation's purpose and outcomes, aligning with billing requirements, whereas the weak note lacks sufficient detail on the consultation purpose and recommendations.
Patient seen for genetics consultation. Basic assessment performed.
Consultation requested to evaluate genetic implications of the patient's current symptoms under hospital admission.
Recommendations include consideration for specific genetic tests linked to observed symptoms.
- Assessment notes include differential diagnosis considerations.
- Recommendations align with genetic testing guidelines and justify limited scope consultation.
