What is E078?

E078 is the OHIP premium fee code for Chronic Disease Assessment. This premium helps compensate  physicians for the added complexity of working with chronic disease.

How does it work?

E078 is only payable on certain out-patient assessments and is a percentage-based premium. This means it needs to be added to another eligible code in order for it to work. It will then apply 50% to the assessment code you’ve added it to.

For example, let’s say you bill A263 (Medical Specific Assessment), which has a value of $82.90. By adding E078, you’ll get an extra 50%, which will bring the entire assessment to $124.35 (the chronic disease premium added an extra $41.45).

Assessment Code + 50% Premium Total
A263 = $82.90 E078 = $41.45 $124.35


Who can bill E078?

Of course, there are some restrictions when using it; such as location, specialty, and diagnostic code. For instance, it can be added as a premium to out-patient assessments only. It’s therefore not applicable for any admitted inpatients, long-term care facility patients or patients in the emergency department.

E078 is only eligible under the following specialties:

Geriatrics
Endocrinology & Metabolism
Neurology
Pediatrics
Pathology
Physical Medicine
Therapeutic Radiology
Medical Oncology
Infectious Disease
Respiratory Disease
Rheumatology
Hematology
Clinical Immunology
