1What Is the W113 OHIP Code?
The W113 OHIP billing code pertains to a complex neurological assessment performed by neurologists. This assessment is distinct as it focuses on the ongoing management of complex neurological disorders such as advanced Parkinson's disease, post-stroke epilepsy, or progressive neurodegenerative illnesses in long-term care in-patient settings. Complex neurological assessments are essential for managing patients whose neurological conditions require continuous, specialized monitoring and adjustment of ongoing treatments.
In practice, this service is not intended for initial evaluations or the management of uncomplicated conditions like carpal tunnel syndrome or Bell's palsy. Therefore, it's important to ensure that W113 is used strictly for patients with an established, documented chronic complex neurological diagnosis. Missing these specific conditions can lead to issues in billing for this code.

3Eligibility Requirements
To bill W113, several eligibility criteria must be met:
-
Initial Evaluation Exclusion: The complex neurological assessment cannot be billed for the initial evaluation of a patient by the physician.
-
12-Month Frequency Cap: This service is limited to a maximum of six complex neurological assessments per patient, per physician, within a 12-month period. Exceeding this will result in the service being adjusted to a lesser-paying assessment code.
-
Chronic Complex Condition Requirement: The patient must have an established diagnosis of a chronic complex neurological disorder, which must be documented in the patient's medical record.
-
Concurrent Service Prohibition: Code E078 is not eligible to be billed on the same day as W113/A113.
-
Documentation: Start and stop times must be clearly documented in the patient’s permanent medical record to avoid fee adjustments.

5Weak vs. Strong Note Examples
The strong note succeeds because it includes documentation of start and stop times, a clear indication of the chronic condition, and detailed notes on the management plan, which are all required for proper use of the W113 code.
Patient seen for ongoing issues. Assessment completed.
Patient with advanced Parkinson’s seen for ongoing management.
Thorough assessment conducted focusing on balance and medication adjustment.
Documented progression of disease state and treatment plan adjustments.
