1What Is the W236 OHIP Code?

The W236 code under OHIP is designated for repeat consultations in internal medicine. It allows physicians to conduct follow-up consultations when a patient's health condition necessitates a second look. This is particularly applicable in long-term care settings where patients with chronic conditions, such as decompensated heart failure or uncontrolled diabetes, require periodic reassessment by an internist.

This code is often missed because it requires a new written request from the referring provider, which distinguishes it from routine follow-ups. Incorrectly classifying visits without the written referral can lead to billing adjustments.

3Eligibility Requirements

To be eligible to bill W236 under OHIP, several specific conditions must be met:

  • A new written request from a referring physician, nurse practitioner, or dental surgeon is mandatory for each repeat consultation.
  • The code can only be used six months after a Periodic health visit as specified in the Nursing Homes Act.

Regarding virtual care, W236 can be billed as W236A if delivered via video, but it is not eligible when conducted by telephone, as outlined in Appendix J, Section 1 of the OHIP Schedule.

4What Your Clinical Note Must Show

1Documentation Needed for W236 Billing

To successfully bill this code, ensure the following documentation is part of the patient's file:

  • A new written request for the repeat consultation from the referring physician, nurse practitioner, or dental surgeon
  • Detailed clinical notes outlining the changes or exacerbations in the patient's condition
  • Evidence of a six-month gap if following a Periodic health visit

5Weak vs. Strong Note Examples

The strong note succeeds by including a current referral and detailed information about the clinical changes and management plan, which are missing in the weak note.

Weak Note

Reviewed patient's diabetes. Follow-up recommended. No new referral.

Strong Note

Consultation conducted following new referral from Dr. Smith due to worsening diabetes control since the initial consultation.

Discussed changes in medication and management plan in detail.

  • Referral document from Dr. Smith
  • Clinical evidence supporting the change in condition
