What is the A225 OHIP Billing Code?

The A225 code under OHIP is designated for consultation services within the field of Medical Genetics and Genomics. This billing is specifically for assessments rendered following a written referral request for consultations outside of hospital settings, such as in-office or outpatient clinics. Commonly, these consultations involve complex genetic assessments, pedigree construction, and the interpretation of genetic testing results.

Physicians often miss billing or incorrectly bill A225 due to incomplete documentation or inadequate referral details. Ensuring a proper referral and comprehensive recording of the consult content is crucial to avoid payment reductions or claim denials.
