X150 – Mechanical evaluation of knee
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
Mechanical evaluation of knee is a miscellaneous diagnostic radiology examination. This service is comprised of two components: a professional component (P fee) for the physician's interpretation and a technical component (H fee). The technical component (H fee) is only eligible for payment when the service is rendered in a hospital. As per , the technical component is not payable if the service is provided to an out-patient who is subsequently admitted to the same hospital within 24 hours for the same condition. Referral may be made by a physician, nurse practitioner, or, under specific circumstances, an oral and maxillofacial surgeon as detailed on .
When to Use
- Use X150 for the professional interpretation of a mechanical knee evaluation when a formal diagnostic radiology report is generated.
- Use this code when the service is requested by a physician or nurse practitioner for a patient requiring a formal mechanical assessment of the knee joint.
Common Pitfalls
- Attempting to bill the technical component (H fee) for services performed in a private clinic or office setting, which is strictly prohibited.
- Billing the technical component for an outpatient who is admitted to the same hospital within 24 hours for the same condition, as this violates the GP11 admission rule.
- Failing to maintain the required quality assurance documentation, which is a mandatory prerequisite for claiming the technical component.
Billing Tips
- Ensure the professional component (P fee) is clearly linked to the diagnostic report, and only bill the technical component (H fee) if the service occurs within a hospital facility.
- When providing urgent after-hours services in a hospital, ensure you select the correct Special Visit Premium (C102-C110) based on the time and patient sequence, as these are mutually exclusive with each other.
