Increasing cost of having babies

Increasing Cost of Having Babies

  • The State of Texas’ Medicaid program is spending over $2.2 billion a year on birthing and delivery costs.

  • The cost of infant care is increasing by almost 10% each year.

  • A small number of very expensive infants account for over 50% of cost.

  • The factors that contribute to these ever increasing costs are not well understood.

Needed data

Needed Data

  • In order to conduct this analysis, state staff need to examine data from several disparate systems (registries and transaction systems). Including:

    • Medicaid enrollment and eligibility data

    • Medicaid utilization claims

    • Hospital Discharge

    • Birth Certificates

    • Birth Defects Registry

  • These data come from vastly different systems, are produced for different reasons, and are administered by different entities.


Business case

Business Case

  • Linking Medicaid birth data to State Vital Statistics Natality data

    • Texas is currently expending in excess of $2.2 billion per year in birth and delivery related services.

    • More than 55% of all births in Texas are paid by Medicaid.

    • Costs related to infant care are growing almost 10% per year.

    • NICU utilization is growing faster than expected.


Business case cont

Business Case (cont.)

  • Over 50% of costs are attributable to extremely premature infants, who account for about 2% of births.

  • The relationship between risk factors identified on birth certificate and Medicaid DRG has not been established.

  • The relationship between NICU utilization and these risk factors has not been established.


Business case cont1

Business Case (cont.)

  • It is very difficult to relate a newborn with the birth mother in transaction data.

  • Because of this, it is difficult to:

    • Examine patterns of maternal conditions associated with poor birth outcomes;

    • Understand the medical history of birth mother; and

    • Know the birth outcomes of previous children.

  • Thus, it is impossible to identify high risk pregnancies.


Other cases

Other Cases

  • HHSC staff have identified other instances where identity resolution would improve policy decisions and business processes.

    • Migration of children across Medicaid/CHIP.

    • Nursing home clients receiving acute care services.

    • SSI children in foster care.

    • Utilization of other safety net programs.
