1What Is the A220 OHIP Code?

The A220 billing code is used for a special genetic consultation within Ontario's healthcare framework, specifically under OHIP. This code is applicable to consultations that involve detailed assessment and direct patient interaction for suspected hereditary conditions. Standard consultations often address single suspected genetic disorders where pedigree assessment and genetic counseling fit within the consultation timeframe.

A common reason this code might be missed is due to the complex requirements for documentations, such as the need for precise start and end times of the consultation. Additionally, failure to obtain a proper referral can result in the service being downgraded to a lesser fee.

Given the detailed nature of such consultations, which must last a minimum of 75 minutes, the A220 code allows specialists in medical genetics to provide thorough assessments and tailored recommendations for patients facing complex genetic issues.

3Eligibility Requirements

To be eligible for billing under the A220 code, the following requirements must be met:

  • Referral: A written request from a referring physician, nurse practitioner, or dental surgeon who has professional knowledge of the patient.
  • Duration: The consultation must involve at least 75 minutes of direct patient contact. This time excludes any other separately billable procedures.
  • Documentation: Exact start and stop times must be recorded in the patient's permanent medical record.

The service can be rendered once per two consecutive 12-month periods for the same diagnosis, except under specific conditions for hospital inpatients or emergency department visits, where a second service is allowed within the same period. For unrelated diagnoses, one service is permitted every 12 months.
