1What Is the W004 OHIP Code?
The W004 billing code allows physicians to claim OHIP reimbursement for a general re-assessment of patients residing in nursing homes. This re-assessment is crucial for ongoing monitoring and management of patients whose conditions may change over time, particularly in long-term care settings.
This assessment is comprehensive, similar to an initial general assessment, but focuses on evaluating any substantial changes in the patient’s condition or medication regimen since their last assessment. Physicians are required to document any significant findings and update care plans accordingly, ensuring the patient’s treatment remains current. However, W004 can often be overlooked due to its similarity with initial assessments, where physicians may not account for all qualifying details during documentation.

3Eligibility Requirements
The W004 code applies under specific eligibility criteria:
- Location: The assessment must take place in a nursing home setting per the Nursing Homes Act.
- Frequency: This service can be billed twice per 12-month period per patient, per physician, unless related to a hospital admission which allows for more frequent billing.
- Time Recording: Physicians must document the start and end times of the assessment in the patient's medical record.
- Interval: W004 can be billed no sooner than six months following a periodic health visit under the Nursing Homes Act.
It’s important for physicians to note that any service billed in excess of the defined frequency may be reimbursed at a lesser rate.
