OHIP billing for general internal medicine in Toronto

Internal medicine consultations and assessments (including A135 for a general assessment and consult codes such as C003 or C004 depending on setting) are sensitive to documentation depth, time, and whether multiple problems are managed in one encounter. Toronto has the province’s highest concentration of academic hospitals, multi-site groups, and referral volume. Specialists here often bill across two or more facilities in the same week, which is where version codes, premiums, and split-site rules create revenue drift.

Toronto healthcare context

Toronto has the province’s highest concentration of academic hospitals, multi-site groups, and referral volume. Specialists here often bill across two or more facilities in the same week, which is where version codes, premiums, and split-site rules create revenue drift.

University Avenue and Bay Street form Toronto's main hospital cluster. Toronto General, Mount Sinai, SickKids, Princess Margaret, and Women's College sit within a few blocks of each other. General internal medicine physicians here often bill across more than one site in the same week, which is where version codes and setting rules create leakage. Before early rounds, many staff stop at Neo Coffee Bar on Bay Street rather than the hospital cafés.
