Creates Procedure Resource

Creates a Past Surgical History or Ocular Surgical History clipboard entry. Required: subject (Patient reference), code (1-2 SNOMED CT codings), status (must be completed — this is the only accepted value), and identifier with value of PSX (Past Surgical History) or OSX (Ocular Surgical History) — omitting the identifier, or sending any other value, fails the request outright rather than falling back to a default section (unlike Condition create). category is always set by the server to DIAGNOSIS/"Diagnosis" regardless of what's sent. There is no Update operation for Procedure.
