Doctors, hospitals and insurers are bracing for possible disruptions on Oct. 1 when the U.S. health-care system switches to a massive new set of codes for describing illnesses and injuries.
Under the new system, cardiologists will have not one but 845 codes for angioplasty. Dermatologists will need to specify which of eight kinds of acne a patient has. Gastroenterologists who don’t know what’s causing a patient’s stomachache will be asked to specify where the pain is and what other symptoms are present—gas? eructation (belching)?—since there is a separate code for each.
In all, the number of diagnostic codes doctors must use to get paid is expanding from 14,000 to 70,000 in the latest version of the International Classification of Diseases, or ICD-10. A separate set of ICD-10 procedure codes for hospitals is also expanding, from 4,000 to 72,000.
