A defect in the coding of HealthCare.gov was responsible for the glitch in the website which sent incorrect tax information to 800,000 enrollees, according to The Hill.
Last Friday, federal officials said the government had sent erroneous tax information to 800,000 people who signed up for health coverage on the federal exchange. The forms displayed incorrect benchmark premiums, which are used in calculating the tax credits consumers will receive to subsidize the cost of their premiums.
In a statement, a federal health official said the information used to calculate the subsidies was wrong on approximately 20 percent of tax forms, listing 2015 data rather than 2014 data, due to "an intermittent defect in the code that was used to create these forms," according to the report.
