What are the billing rules for A136A?

Specialists bill from the Consultations and Visits listing for their own Royal College specialty on file with the Ministry, here Internal Medicine (13) (GP9). Needs a new written, signed request naming the referrer and their billing number (GP16, GP19). Repeat consultations don't count toward the consultation limits, but if the repeat-consultation conditions aren't met OHIP pays a general or specific assessment instead (GP18).

Why is A136A rejected?

ARF: OHIP describes this as 'Missing Physician Referring Number': a consultation claim needs the referring physician's or nurse practitioner's billing number (GP16). AT2: OHIP describes this as 'Must include video modality': this code is video-only in Appendix J, so it can't be billed by phone with K301A (AJ2).
