1What Is the W184 OHIP Code?

Overview of W184

The W184 OHIP billing code is designated for general re-assessments of patients in nursing homes, conducted by neurologists. This code applies particularly to long-term residents needing ongoing evaluation of neurologic conditions such as advanced Parkinson's disease, dementia, or recurrent seizures.

Unlike initial assessments, a general re-assessment does not require a comprehensive history review, focusing instead on the current status and changes in the patient's condition. Often, these assessments are vital for adjusting management plans based on disease progression.

Importantly, physicians may overlook W184 when a patient's condition subtly changes over time, thinking only significant health events merit a re-assessment. However, ensuring accurate documentation and meeting visit frequency limitations are key for billing compliance.

Eligibility Requirements

When billing under W184, specific eligibility criteria must be met:

  • Frequency Limit: General re-assessments are capped at two per 12-month period, per patient per physician, except when associated with hospital admissions. Exceeding this limit results in a reduced fee adjustment.
  • Interval Specification: This code can only be billed 6 months after a periodic health visit as defined under the Nursing Homes Act.

Documentation: Physicians must record the exact start and end times of the service in the patient's medical record as a requirement. Compliance with these eligibility rules ensures proper reimbursement and adherence to OHIP guidelines.
