Section 75.21. Rates and fees

A  company  shall,  with the approval of the commissioner, fix maximum
  rates and fees to be charged in-patients or out-patients of each project
  for the  facilities  and  services  provided  by  the  company  to  such
  in-patients  or out-patients, the average of such rates and fees for any
  one project not to exceed the maximum average rates and fees  determined
  by  the  commissioner before any commitments are made by the company for
  the  construction,  acquisition,  reconstruction,   rehabilitation,   or
  improvement  of  the  project.  The commissioner upon his own motion, or
  upon application by the company or lienholder may  vary  the  amount  of
  such rates and fees from time to time so as to secure, together with all
  other   income  of  the  company,  sufficient  income  to  meet,  within
  reasonable limits, all necessary payments by the  said  company  of  all
  expenses, including fixed charges, sinking funds, and reserves.
