1What Is the A188 OHIP Code?
In neurology, the A188 billing code is utilized for partial assessments. These assessments are limited in scope, typically addressing a specific aspect of a neurological condition. For instance, it’s often used for interval visits to evaluate a patient's response to medication changes, such as monitoring seizure frequency or reviewing a new imaging report.
Partial assessments are concise and focus on the presenting complaint, requiring a brief history, necessary physical examination, and advice tailored to the patient's condition. This targeted approach makes A188 an efficient option for handling specific patient concerns without conducting a comprehensive evaluation. However, due to its limited scope, it's commonly overlooked in favor of more comprehensive codes, especially when physicians miss the opportunity to document specific follow-up visits aligning with the partial assessment criteria.

3Eligibility Requirements
Eligibility
The A188 partial assessment code applies to neurologic assessments that are limited in scope. According to the OHIP Schedule of Benefits, this code is used under the following conditions:
- Service Requirements: A partial assessment must include a history of the presenting complaint, appropriate physical examination, patient advice, and corresponding documentation.
- Documentation: The service is only payable if the start and end times of the assessment are recorded in the patient’s permanent medical record.
- Virtual Care: A188 can be performed virtually and must be billed as A188A when done via video or telephone.
- Hospital In-Patient: The equivalent code for hospital in-patient services is C188.
Note: Ensure compliance with the General Preamble assessment rules to avoid billing issues.
4What Your Clinical Note Must Show
For a successful claim with code A188, the following documentation is crucial:
- Start and end times of the assessment.
- Detailed history of the presenting complaint.
- Results of the relevant physical examination.
- Advice provided to the patient.
- Record of any non-patient-facing time, such as reviewing charts or imaging.
5Weak vs. Strong Note Examples
The strong note succeeds by thoroughly documenting the specific details of history, examination, advice, and recording the necessary timestamps, ensuring it meets OHIP's documentation standards. The weak note lacks this depth and detail, missing critical elements needed for a valid claim.
Patient seen for follow-up regarding medication change. Seizure frequency discussed.
The patient was assessed following a recent change in seizure medication dose. The session began at 10:00 AM and concluded at 10:20 AM.
History: The patient reports a decreased seizure frequency since the last visit. No new side effects noted.
Physical Exam: Focused neurological examination is unchanged since prior visit.
Plan: Continue current medication regimen; reviewed recent MRI results revealing no new findings.
Advised patient on potential side effects and scheduled follow-up in one month.
- Start and end times recorded.
- Comprehensive details documenting history and exam.
- Plan and advice summarized clearly.
