Q593A – Sole Visit Premium COVID-19 vaccine
OHIP Critical Care Code — APPENDIX Q · Schedule of Benefits
Sole Visit Premium COVID-19 vaccine. Eligible Models: FHO, FHN, GHC, PEM RNPGA, WHA, SJHC, TPCA, BSM, GP Focus Care of the Elderly, GP Focus HIV, Homeless Shelter Agreements, Sioux Lookout Agreements.
When to Use
- Use Q593A when a patient attends the office solely for a COVID-19 vaccine injection and no other medical service or assessment is provided during the encounter.
- Apply this premium when the vaccine is administered by a physician or a nurse under the physician's supervision in a primary care model where the patient is enrolled.
Common Pitfalls
- Billing Q593A in conjunction with an office visit code like A007 or A001 is a common rejection, as the premium is intended for 'sole' purpose visits only.
- Submitting Q593A for a vaccine administered during a comprehensive physical or chronic disease management visit will result in a clawback during audit.
Billing Tips
- Ensure the vaccine administration fee (G593A) is billed alongside Q593A to capture both the procedure and the sole-visit premium.
