1What Is the W223 OHIP Code?

The W223 OHIP billing code applies to extended special genetic consultations specifically conducted for patients residing in long-term care facilities such as chronic care hospitals, nursing homes, or Homes for the Aged in Ontario. This code addresses the needs of in-patients who require a comprehensive genetic evaluation typically due to an undiagnosed neurodegenerative or metabolic condition.

For this code, the physician must engage in a thorough consultation, spending a minimum of 90 minutes in direct contact with the patient, which may include interactions with family members. This extended period allows for an in-depth assessment, aiding in the diagnosis and management of complex genetic conditions.

Physicians should note that this billing opportunity is often missed due to misunderstandings around the qualifying settings and time documentation requirements. Ensuring accuracy in timing records and understanding the eligible settings is crucial for successful billing.

3Eligibility Requirements

Eligibility for the W223 billing code requires adherence to several specific criteria:

  • The consultation must occur in a non-emergency long-term care setting, such as a chronic care hospital, convalescent hospital, nursing home, or Home for the Aged.
  • The physician is expected to spend at least 90 minutes in direct contact with the patient and/or their family, exclusive of any time spent on other billable services.
  • This consultation can be billed once per two consecutive 12-month periods for the same diagnosis unless the second consultation is with a hospital in-patient or emergency department patient, 12 to 24 months after the first. If there is a second, unrelated diagnosis, the consultation may be billed once every 12 months.
  • Documentation must include start and stop times within the patient’s permanent medical record.

4What Your Clinical Note Must Show

1Medical Record Requirements for W223

Ensure the following is documented in the patient's permanent medical record:

  • Start and stop times of the service.
  • Written referral request including consulting and referring physician details.
  • Detailed report summarizing findings, opinions, and recommendations sent to the referring provider.

5Weak vs. Strong Note Examples

The strong note provides specific details about the patient interaction, includes exact timing, participant names, and references a follow-up report, all of which are necessary for billing compliance. The weak note lacks essential details such as timing and content specifics.

Thorough history and family pedigree were reviewed, and a detailed physical assessment was conducted.

  • Consultation start and end times: 10:00 AM - 11:45 AM.
  • Discussed potential genetic diagnoses and suggested further genetic testing to confirm suspicions.
  • Comprehensive report completed and sent to Dr. Smith, including findings and specific recommendations for genetic testing.
