How to use this ent code set

It carries the codes the Ontario Schedule of Benefits ties to otolaryngology (specialty 24) — its own consultation and assessment codes, in-patient visits, premiums and the diagnostics or procedures that make up most of a day — sectioned the way a shift sheet reads. Codes open to every specialty that a ent physician also bills (general assessments, forms, special visit premiums) live in the Family Practice and Special visit premiums sets.
Each code links to its full Schedule entry: fee history, restrictions, required diagnoses and the codes it can or cannot be billed with. Fees shown are the current provider or specialist fee; percentage premiums show the percentage they add to the base service.
