attention to their billing department, I'm not sure if they Pay I have to give Medstar less than one star overall here because they are apparently a partner to another operation named Hanger Clinic in Laurel which is a real sorry problem. I say apparently because I'm trying to research why Hanger Clinic has interfered with my once excellent credit rating. I have no idea who they are and I don't care who they are except just another disreputable business perhaps engaged in insurance or medical fraud. While working, or trying to work with Medstar to get information about how they screwed up a visit with them almost two year sago I am not getting any results . They don't care. So I don't care either Medstar, this post is about you and how you are useless and involved with a sleazy partner. User's recommendation: Pay attention to their billing practices and business partners,
