Explanation

Updated October 26, 2026

Repeat consultation by an endocrinologist for a hospital in-patient, for the same problem after another physician has given care in between.

What it covers

A repeat consultation is an additional consultation by the same consultant for the same presenting problem, after another physician has cared for the patient since your first consultation (GP19).

It has all the requirements of a consultation, including a new written request (GP19). C156 is the in-patient code; A156 is the office code and W156 the long-term care code (A98, A102, A103).

Billing rules

  • Needs a new written request from the referring physician, nurse practitioner or dental surgeon; in hospital it may be on the common medical record (GP16, GP19).
  • If the repeat consultation requirements aren't met, it pays as an assessment (GP18).
  • Repeat consultations don't count toward the consultation limits (GP17, GP18).
  • Detention (K001) is only payable after 60 minutes (GP29, GP30).
  • Patients under 16 get an age premium of 10% to 30%, depending on age (GP64).
  • By video only for an in-patient or long-term care resident, and only if you aren't the MRP, no local physician with the expertise is available (documented by the referrer), and the referrer assessed the patient in person within the past 30 days (Appendix J AJ2, A69).

Common rejections

  • ARP: OHIP needs the referring provider's number on a consultation claim; add the referrer's billing number from the written request and resubmit (GP16).
