The Rural Health Open Door Forum (ODF) addresses Rural Health Clinic (RHC), Critical Access Hospital (CAH) and Federally Qualified Health Center (FQHC) issues, as well as some inclusion of other questions and concerns that occur in clinical practice pertaining to other CMS payment systems that also extend into these settings. Topics that frequently arise on this forum often deal with payment & billing for services subject to Health Professional Shortage Area (HPSA) and/or Physician Shortage Area (PSA) status, cost report clarifications, classifications for & qualifications of rural provider types, and the many special provisions being implemented for improving rural health in the Medicare Modernization Act of 2003. Timely announcements and clarifications regarding important rulemaking, quality program initiatives, and other related areas are also included in the Forums.
