1What Is the C193 OHIP Code?

C193 is an OHIP billing code used by psychiatrists to claim payment for specific in-patient assessments. These assessments are crucial when evaluating complex psychiatric conditions such as delirium versus depression in hospitalized patients, assessing suicide risk before discharge, or managing psychotropic medications in the context of other treatments. This code is significant for scenarios that require focused psychiatric input to guide clinical management within the hospital setting.

Clinicians may miss billing C193 if they overlook the nuanced requirements of psychiatric assessments or do not differentiate between in-patient and out-patient settings. Ensuring comprehensive documentation and clarity about the patient’s psychiatric needs are crucial steps in correct billing.

3Eligibility Requirements

Eligibility to bill code C193 requires the service to be rendered to in-patient hospital settings. It can be performed virtually but must be completed via video; telephone assessments do not qualify for this OHIP billing. Note that while C193 is frequently associated with specific psychiatric needs, it is also part of a cluster of related services, each with its distinctive settings and requirements.

C193 rendered virtually should be billed as C193A and adheres to the specific rules for video-only service claims. Always verify individual patient eligibility in terms of existing rules and requirements before proceeding to bill.

4What Your Clinical Note Must Show

1Ensure Proper Documentation

Accurate and complete clinical documentation is essential when billing for C193.

  • Document the clinical need for the psychiatric assessment.
  • Detail the specific psychiatric conditions assessed.
  • Include any psychotropic medication considerations.
  • Provide context of assessment within the in-patient treatment plan.
