Explanation

Routine in-hospital visit by a consulting respirologist while the family physician stays most responsible and asks for continued directive care.

What it covers

C478 is concurrent care by a specialist in Respiratory Disease for a non-emergency hospital in-patient, per visit (A199).

Concurrent care is any routine assessment in hospital by the consultant after their first major assessment, when the family physician remains the most responsible physician but asks the consultant to continue directive care (GP48).

Billing rules

• Limited to 4 claims in the first week of concurrent care and 2 per week after that; extra claims are not paid (GP48).
• Not on the Appendix J virtual care lists, so it can't be billed virtually (AJ1–AJ2).

Common rejections

• AHF: OHIP's message is 'Concurrent or Supportive Care Same Period': check the weekly limits (4 in the first week, then 2 per week) and whether another concurrent or supportive care claim already covers that period (GP48).
