PITTSBURGH — A western Pennsylvania woman charged with purposely and repeatedly dislocating her shoulder so she could get painkillers has been scheduled to plead guilty.

The attorney for Kari Richards, of Latrobe, didn’t immediately return messages seeking comment on the change of plea hearing scheduled Tuesday before a federal judge in Pittsburgh.

Richards was indicted last June on charges she defrauded Highmark Inc.’s Community Blue health insurance plan allegedly by traveling to more than 100 hospitals in 11 states to obtain prescriptions for shoulder dislocations she was causing herself.

During a 16-month period, authorities say Richards sought treatment at hospitals more than 300 times.

Richards allegedly defrauded Highmark’s Community Blue Shared Cost plan by obtaining 190 prescriptions for oxycodone and other opiates between January 2014 and April 2015.
