Organizations should refer to General Guideline 15 in the HEDIS 2019 Volume 2 publication for guidance on reporting members with dual enrollment for the TLM measure. However, when General Guideline 15 allows members to be included in more than one product line deduplicate and count members only once in the measure as follows:
 -Report members with dual Medicaid/Medicare enrollment in the Medicare product line.   Â
 –For other dual enrolled members report the members in the primary product line.
