G841 – Diphtheria, Tetanus, acellular Pertussis, Inactivated Polio Virus, Haemophilus influenza type b (DTaP-IPV-Hib) - paediatric
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service covers the provision of the Diphtheria, Tetanus, acellular Pertussis, Inactivated Polio Virus, and Haemophilus influenzae type b (DTaP-IPV-Hib) vaccine for pediatric patients. The '+' symbol in the Schedule of Benefits indicates this is an add-on code. Where this immunization is the sole reason for the visit, add-on code G700 is also payable once per patient per day. This procedure can be delegated to a physician's employee under the conditions outlined on pages - of the Schedule of Benefits. Note that this service may not be insured under some conditions as per the Health Insurance Act.
When to Use
- Use G841 when administering the pentavalent DTaP-IPV-Hib vaccine to pediatric patients during a dedicated immunization visit.
- Use G841 in conjunction with G700 when the patient presents specifically for this immunization and no other assessment or consultation is billed.
Common Pitfalls
- Billing G841 alongside an assessment code (e.g., A007) is a common error; the immunization is considered part of the assessment and is not separately payable.
- Attempting to bill G700 when an assessment or consultation is also claimed for the same patient on the same day will result in a rejection.
- Billing G841 for patients over the age of 17, as the code is strictly restricted to the pediatric population.
Billing Tips
- Always append G700 to your claim when G841 is the sole reason for the visit to capture the additional premium.
- Ensure you are not billing G841 in the same month as W010, as the immunization is considered a component of the monthly management fee.
