OHIP billing for general internal medicine in London
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. London is a referral hub for a large catchment area. That means consult volume, wait-time pressure, and documentation load are all high. Under those conditions, billing shortcuts show up as lost revenue within months.

Internal medicine outpatient consults often use A135 (standard consultation) when a formal referral exists, with A130 reserved for documented comprehensive encounters of 75 minutes or more. Inpatient work uses C-prefix codes with HIP location and hospital facility identifiers. Consult versus assessment selection is the most common audit trigger when referral letters or documentation do not match the code submitted.
London healthcare context
London is a referral hub for a large catchment area. That means consult volume, wait-time pressure, and documentation load are all high. Under those conditions, billing shortcuts show up as lost revenue within months.
Victoria Hospital and University Hospital at London Health Sciences Centre anchor southwestern Ontario referrals. Consult volume from the wider catchment runs through both campuses. 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. Piping Kettle Soup Co. on Commissioners Road East is a familiar quick stop near Victoria Hospital rather than the on-site cafeteria.
How general internal medicine is practised in London
General internists in Ontario typically mix hospital rounds, consult coverage, and community clinic sessions. The same physician may bill assessments, consults, and follow-ups for different patients in one week. Revenue leakage usually comes from under-coded consult depth and missed modifiers, not from volume.
