Though few patients appeal coverage denials generally, when UnitedHealth members appeal denials based on nH Predict estimates—through internal appeals processes or through the federal Administrative Law Judge proceedings—over 90 percent of the denials are reversed, the lawsuit claims. This makes it obvious that the algorithm is wrongly denying coverage, it argues. > But, instead of changing course, over the last two years, NaviHealth employees have been told to hew closer and closer to the algorithm's predictions. In 2022, case managers were told to keep patients' stays in nursing homes to within 3 percent of the days projected by the algorithm, according to documents obtained by Stat. In 2023, the target was narrowed to 1 percent.
