Houston Chronicle: Hundreds of doctors in Texas are dropping out of the federal health care program for senior citizens as physician reimbursement for Medicare declines. More than 300 Texas doctors have dropped the program in the last two years, including 50 in the first three months of 2010, the Houston Chronicle, which compiled the data, reported Tuesday. The Texas Medical Association did a survey in 2008 that found 42 percent of Texas doctors participating in the survey said they were no longer accepting all new Medicare patients. Among primary-care doctors, the percentage was 62 percent. Medical association officials said the Chronicles' new numbers surpassed their expectations.
