X166 – Examination Using Portable Machine “in Home” Add to First Examination Only
OHIP Laboratory Code — Miscellaneous Examinations · Schedule of Benefits
This code is an add-on to the first radiological examination performed with a portable machine in a patient's home setting. The definition of 'home' includes a nursing home. This code cannot be used for services provided in a hospital. It can only be claimed once per day for a given location, irrespective of the number of patients examined. The facility cost for X166 is detailed in the Schedule of Facility Costs for ICHSCs.
When to Use
- Use X166 when performing the first diagnostic X-ray on a portable machine for a patient residing in a long-term care facility or private home.
- Apply this code specifically as an add-on to the primary diagnostic imaging fee (e.g., X001 or X002) when the equipment must be transported to the patient's location.
Common Pitfalls
- Claiming X166 for multiple patients at the same facility on the same day; it is restricted to a single claim per location per day regardless of patient volume.
- Attempting to bill X166 for portable imaging services performed within a hospital setting, which is explicitly prohibited by the Schedule of Benefits.
Billing Tips
- Ensure the primary diagnostic code is billed on the same claim as X166 to avoid rejection, as X166 is an add-on code that cannot stand alone.
