J890 – Overnight sleep study - diagnostic
OHIP Cardio-Thoracic Surgery Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
J890 is a Level 1 overnight sleep study with continuous monitoring of oxygen saturation, ECG and Ventilation (airflow and respiratory effort) and additional monitoring to stage sleep (including all of the following: EEG, EOG and sub-mental EMG). This study must be rendered in a specialized facility, which is defined as: a. a facility where patients are on ventilatory support and that specializes in the treatment of adults with conditions such as amyotropic lateral sclerosis or polio; or b. a paediatric hospital where there is a Paediatric ICU and that treats children with respiratory control disorders. This service includes a professional component (P Fee) and a technical component (H Fee).
When to Use
- Use J890 for diagnostic polysomnography in a specialized facility for patients requiring ventilatory support due to neuromuscular conditions like ALS or polio.
- Use J890 for pediatric patients in a hospital with a PICU requiring diagnostic sleep staging for complex respiratory control disorders.
Common Pitfalls
- Billing J890 in conjunction with any EEG codes (G414, G415, G418, G540-G546, G554, G555) will result in automatic rejection as these are considered inclusive.
- Submitting J890 alongside J889 for the same patient within a 12-hour window is prohibited and will trigger a payment denial.
- Attempting to claim special visit premiums with J890 is ineligible, as sleep studies are excluded from premium eligibility.
Billing Tips
- Ensure the facility meets the strict definition of a specialized unit (neuromuscular support or pediatric PICU) to avoid audit recovery, as this is the primary differentiator from standard sleep lab codes.
- Monitor the annual limit of two studies per 12-month period for the combined total of J890 and J889 to prevent automatic rejection of subsequent claims.
