Immunization with the paediatric DTaP-IPV vaccine (diphtheria, tetanus, pertussis, polio). Add G700 when it's the only reason for the visit.

What it covers

G840 is the immunization code for the paediatric diphtheria, tetanus, acellular pertussis and inactivated poliovirus vaccine (DTaP-IPV) (J54).

When the vaccine also contains Hib, bill G841; the adult Tdap vaccine is G847 (J54).

Billing rules

• Marked (+): when the immunization is the sole reason for the visit, add G700, once per patient per day however many vaccines or (+) procedures are given (J3, J54).
• G700 is not payable in hospital, and is paid at 15% of its fee for patients enrolled to a capitation-based group (J3).
• May be delegated to trained office staff, even when you aren't on site, for your own patient; the chart must name who gave it (GP62–GP63).
• Payable on the same day as a counselling service by the same physician (GP58).
• The Schedule notes an immunization may be uninsured in some circumstances and refers to section 24 of Regulation 552 under the Health Insurance Act (J54, AA1).
• FHO: a Schedule 2B core service, so for enrolled patients shadow billing is 50% of the fee (Agreement p.59 §4.3–4.4, p.89).
• FHO: childhood immunizations count toward the annual childhood immunization bonus for enrolled patients aged 30–42 months (Agreement p.65 §8.1).

Often billed with

• G700 when vaccines (alone or with other (+) procedures) are the only reason for the visit (J3, J54).
• An assessment such as A007 (intermediate assessment or well baby care) when the vaccine is given at a regular visit; G700 isn't added then, because the vaccine isn't the sole reason (A4, J3).

Common rejections

• EH2: The health card version code on the claim doesn't match OHIP's record, often because the patient has a newer card; get the current version code and resubmit.
• VH9: The health number isn't registered with the Ministry; with childhood vaccines this can be a newborn whose registration isn't complete, or a number copied wrong.
• EQB: OHIP describes this as 'Solo billing number inactive on service date': the solo billing number on the claim wasn't active on the day of service.
• VJ7: OHIP received the claim more than three months after the service date, so it was rejected as stale-dated (GP9).
• VH8: The date of birth on the claim doesn't match OHIP's record for that health number; correct it and resubmit.
