1What Is the A054 OHIP Code?

What is the A054 Medical Specific Re-assessment?

The A054 billing code is used by physicians in Preventive Medicine to claim for a medical specific re-assessment. This service requires a full, relevant history and physical examination of one or more body systems related to the patient’s ongoing medical condition.

Typically, this type of re-assessment is utilized in scenarios such as follow-ups after the initiation of post-exposure prophylaxis or after completion of interrupted vaccine series. It is critical in ensuring continuity of care and confirming the effectiveness of treatment plans.

This code is often missed due to lack of comprehensive documentation or misunderstanding of the time-recording requirements necessary for billing.
