If the implementation of ICD-10 diagnosis codes is delayed by an act of Congress, as seems likely, doctors may be spared a headache -- but healthcare CIOs will gain one. The Centers for Medicare and Medicaid had set forth a firm October 1 deadline for the implementation of a new and vastly expanded system of diagnosis and insurance billing codes, a transition that has been in the works since the 1990s and had been pushed back repeatedly. On Thursday, the US House of Representatives passed a "doc fix" bill including a one-year extension of the deadline.
