Medical + Pharmacy Open Claims – Data Quality Notice - 5/8/2025

Change Healthcare Cyberattack Impact: 2024 Disruption

The declines in both Medical and Pharmacy claim volumes in 2024 are primarily due to the industry-wide disruption caused by the Change Healthcare cyberattack in February 2024. This incident significantly impacted claim submission and processing across the U.S. healthcare system.

Impact​

  • Year-over-year comparisons for 2024 are less reliable
  • Forecasting models and historical backtests may be skewed due to incomplete or delayed claims
  • Decreased visibility into medical and pharmacy utilization patterns for affected periods

Our Gameplan​

To address these disruptions, we are developing a panelized view that adjusts for 2024 anomalies. This will allow clients to minimize noise and improve model accuracy when analyzing 2024 data.

Interim Recommendations​

While we work on the updated panel:

  • In the coming weeks users can use functions to aggregate daily data to weekly or monthly level within our Workspace tool to evaluate short-term trends. In the meantime data is available at a Daily level temporal filter.
  • Normalize spend and claim counts by daily active users to approximate scaled patient behavior.
  • Avoid direct y/y comparisons using raw 2024 data.
  • Users should leverage the Code options to extract large volumes of data. Download CSV options with this data may time out and are limited to small samples.

Coming Soon​

  • Temporal + Spatial Aggregations
  • Demographic Cuts (Age, Gender)
  • Panelized View by 6/1/2025 (Beta version pending testing)
