1What Is the A183 OHIP Code?
What is A183?
The A183 OHIP billing code is designated for medical specific assessments in the field of neurology. This code is typically used in office or outpatient clinic settings, aiming to address one well-defined neurological issue without requiring a full consultation. Common scenarios include evaluating a known epilepsy patient after a medication change or assessing a headache patient's response to prophylactic measures. This billing typically does not necessitate a new written referral, focusing more on ongoing care rather than initial diagnoses.
Medical specific assessments (A183) are crucial for providing efficient and focused neurological care. However, they are often missed in billing due to lack of comprehensive documentation or misunderstanding of eligibility criteria. Properly recording the required information can prevent revenue loss and ensure compliance with OHIP regulations.

3Eligibility Requirements
Eligibility Requirements
A183 is guided by specific criteria outlined in the OHIP Schedule of Benefits:
- General Assessment Requirements: Must be conducted in a location other than a patient's home. Requires a full history including elements such as presenting complaint, family, past medical, and social history, and a functional inquiry into all body systems. Except for certain exceptions, all body parts and systems must be examined.
- Time Recording: The service is non-payable without recorded start and end times on the patient's medical record, as outlined in General Preamble GP7.
- Virtual Delivery: A183 assessments can be performed via video or telephone, billed under A183A, as specified in Appendix J, Section 1.
- Hospital In-Patient Equivalent: Use C183 for the same service when rendered to a hospital in-patient.
