  <description
               value="Codes identifying the HEARTLAND risk score and its tier when either is carried on an Observation rather than on a RiskAssessment — for example an Observation referenced from HeartlandRiskAssessment.basis holding the point total. The score is a non-validated implementation heuristic: the total is a point count, not a probability, and the tier assigns monitoring intensity rather than predicting an outcome."/>
