1What Is the W345 OHIP Code?

What is the W345 OHIP Billing Code?

The W345 code is used for billing consultations provided by otolaryngologists (ENT specialists) under Ontario's Health Insurance Plan (OHIP). This fee code is commonly utilized in long-term care settings, such as nursing homes, where moving patients to external clinics might not be feasible.

In typical use, an ENT consultation involves evaluating conditions like recurrent aspiration, chronic otitis, swallowing issues, or a neck mass. These situations often necessitate specialized ENT input, especially when patients cannot be transported easily.

This code can be easily overlooked if physicians are unfamiliar with the specific settings and clinical criteria that justify using W345 over a general assessment or other billing codes.

3Eligibility Requirements

Eligibility Requirements for W345

  • Frequency: This code can be billed once per two consecutive 12-month periods for the same patient, physician, and diagnosis.
  • Exceptions: A second consultation can be billed in the same period if it is for a hospital inpatient or an Emergency Department patient, provided it's more than 12 months but less than 24 months after the first.
  • Unrelated Diagnosis: If the consultation is for a clearly unrelated diagnosis, W345 may be billed once every 12 months.
  • Excess Services: If services exceed the specified limits, they are compensated at the general or specific assessment rate.

It is crucial to document the patient's condition and the necessity of the consultation adequately, detailing the ENT-specific concerns that warrant this billing code.
