1What Is the W275 OHIP Code?

What is W275?

The W275 code is designated for limited consultations in the field of infectious diseases, specifically focusing on non-emergency long-term care in-patient services. This includes consultations on patients in facilities such as chronic care hospitals, convalescent hospitals, nursing homes, and homes for the aged.

These consultations are designed to address specific and often straightforward clinical questions that require expert input. Common scenarios involve answering focused inquiries on infection management or antibiotic decisions during a facility outbreak. The service is distinct in nature as it demands less of the physician's time compared to a full consultation, allowing for efficient use of healthcare resources.

Why is it Commonly Missed?

Physicians often miss billing W275 due to misconceptions about its applicability limited to virtual or emergency settings. Another common oversight occurs when physicians misinterpret the eligibility criteria, particularly the requirement for the consultation to follow a written referral from a qualified practitioner.

3Eligibility Requirements

Eligibility Requirements

W275 is applicable for non-emergency long-term care in-patient consultations within infectious disease settings. These settings include chronic care facilities and designated long-term beds, but exclude palliative care beds. It's crucial that the consultation follows from a written request by a physician, nurse practitioner, or dental surgeon.

W275 can be delivered virtually, but is limited to video consultations only—phone calls do not qualify. This consultation type is intended for less comprehensive inquiries, and adherence to frequency limits based on patient, physician, and diagnosis is necessary.

4What Your Clinical Note Must Show

1Essential Documentation

Ensure the following points are covered in the patient's record to support billing for a W275 Limited Consultation:

  • Document the written request from a referring physician, nurse practitioner, or dental surgeon.
  • Clearly outline the specific question or focused issue addressed during the consultation.
  • Detail the consultation setting, confirming it is within a long-term care environment such as a nursing home or chronic care hospital.
  • Include evidence that the service was provided through approved virtual means if applicable (video only).

5Weak vs. Strong Note Examples

The strong note provides a detailed account of the consultation, including referral details and the rationale behind the clinical decision, in contrast to the weak note's generic summary lacking specific context.

Weak Note

Consulted for infection management. Assessment completed.

Strong Note

Consultation requested by Dr. Jones to address specific antibiotic regimen during facility outbreak. Available documentation reviewed, examined patient’s clinical status on video call, and provided recommendations.

  • Referral letter from Dr. Jones attached.
  • Assessment finding: need for alternative antibiotic due to resistance pattern.
  • Virtual consultation completed via video conferencing as per regulations.

6Common Reasons This Code Is Missed
