Zero-fee tracking code that records colorectal cancer screening for an enrolled patient aged 45 to 74, for the preventive care bonus.

What it covers

Q133A is the colorectal cancer screening tracking code (OMA Q-codes guide p.7, p.18). Tracking codes mark a patient as having received a preventive service, which counts toward the physician's preventive care bonus percentage for that category (OMA Q-codes guide p.17).

It is not in the Schedule or Appendix Q. The source is the 2020 OMA Q-codes guide.

Billing rules

• Bill at zero. The remittance advice pays zero with explanatory code 30, 'this service is not a benefit of OHIP' (OMA Q-codes guide p.17).
• Submit it with your normal fee-for-service and premium billing (OMA Q-codes guide p.17).
• The colorectal bonus is based on enrolled patients aged 45 to 74 on March 31 who had a fecal occult blood test in the 30 months before March 31 of the fiscal year (INFOBulletin 260805; OMA Q-codes guide p.17). The same guide notes the FIT has replaced the older gFOBT kit (OMA Q-codes guide p.13).
• Bonus tiers Q118A to Q123A run from 15% to 70% of that population and are claimed at zero (AQ10–AQ11).
• Appendix Q lists the colorectal tiers for RNPGA, BSM, GHC, SJHC, SEAMO, WHA and CCM/FHG physicians who meet the minimum roster (AQ10–AQ11). The April 2026 FHO agreement gives FHO physicians only the influenza and childhood immunization bonuses (Agreement p.65 §8.1).
• Patients with inflammatory bowel disease, a colonoscopy in the last 10 years, a history of malignant bowel disease or a condition needing surveillance colonoscopies are excluded with Q142A (OMA Q-codes guide p.18).

Common rejections

• EH2: The health card version code on the claim doesn't match OHIP's record for the patient; get the current version code and resubmit.
• VH8: The date of birth on the claim doesn't match OHIP's record for that health number; correct it and resubmit.
• V70: The Ministry's description for V70 is a service date later than the claim file or batch creation date; check the service date.
• EQE: The physician isn't registered as a member of the group whose number was used on the claim; check the group number.
• VJ7: OHIP received the claim more than three months after the service date, so it was rejected as stale-dated.
