How Payments are Made with a Disease Hierarchy,,
"EXAMPLE:      If a beneficiary triggers Disease Groups 148 (Decubitus Ulcer of the Skin) and 149 (Chronic Ulcer of Skin, Except Decubitus), then DG 149 will be dropped.  In other words, payment will always be associated with the DG in column 1, if a DG in column 3 also occurs during the same collection period.  Therefore, the M+C organization’s payment will be based on DG 148 rather than DG 149.",,
