   9 // This array provides abstraction of billing code types.  This is desirable
  10 // because different countries or fields of practice use different methods for
  11 // coding diagnoses, procedures and supplies.  Fees will not be relevant where
  12 // medical care is socialized.  Attribues are:
  13 //
  14 // id   - the numeric identifier of this code type in the codes table
  15 // fee  - 1 if fees are used, else 0
  16 // mod  - the maximum length of a modifier, 0 if modifiers are not used
  17 // just - the code type used for justification, empty if none
  18 // rel  - 1 if other billing codes may be "related" to this code type
  19 // nofs - 1 if this code type should NOT appear in the Fee Sheet
  20 // diag - 1 if this code type is for diagnosis
  21 //
