G100 – Haemophilia infusion
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Haemophilia infusion includes routine clinic visits (system/drug/infusions technique/blood work review and physical examination), counselling/psychotherapy/genetic counselling of patients and relatives and supervised haemophilia infusion when required. The specific elements of this service are all services performed by the specialist in charge of the patient during a one-week period in providing non-emergency care to the patient who is self administering haemophilia therapy, including providing any advice and supervision in regard to self administration, whether by telephone or otherwise and even when initiated by the patient, patient's relative(s), or their representative and including providing all premises, equipment, supplies and personnel used by the specialist in charge of the patient to perform these services.
When to Use
- Use G100 as a weekly management fee for stable patients who are self-administering haemophilia therapy at home.
- Apply this code to cover routine clinic visits, telephone consultations, and supervision of self-administration occurring within a single seven-day period.
Common Pitfalls
- Do not bill G100 in addition to hospital daily care or in-hospital infusion fees; these services are mutually exclusive for the same patient in the same period.
- Avoid billing G100 for emergency visits, as these must be claimed using standard visit codes (e.g., A007) and applicable premiums instead of the weekly management fee.
Billing Tips
- Since G100 is a weekly management fee, ensure you only claim it once per seven-day period regardless of the number of telephone calls or routine clinic interactions provided during that week.

When physicians are required to make emergency visits to see patients on any form of home/self care haemophilia infusion, the appropriate visits and premiums may be claimed. When the patient requires hospitalization, the appropriate fees for daily care and in-hospital infusions may be claimed instead of G100.
