1What Is the A180 OHIP Code?

The A180 code is used for billing special neurology consultations in Ontario under OHIP. It is specifically for consultations that involve at least 75 minutes of direct patient contact, allowing comprehensive evaluation and management of complex neurological conditions. It’s critical due to the depth of assessment it supports, thus facilitating improved patient outcomes.

Neurologists benefit from A180 billing when dealing with patients requiring thorough evaluations, such as those with unclear diagnoses or complex treatment plans. Missing key requirements, like not recording exact times, can result in downgrading to a lower fee service code.
