1What Is the W435 OHIP Code?
The W435 OHIP billing code serves as a billing mechanism for limited consultations provided by internal medicine specialists. These consultations are typically rendered in long-term care settings, focusing on a specific clinical question such as medication adjustments due to renal decline or abnormal electrolyte correction.
Limited consultations differ from comprehensive consultations due to their specificity and scope. Physicians often miss using this code because it shares the same fee with repeat consultations, which makes understanding whether the issue is new or a re-evaluation vital.
