Pennsylvania Capitation Payments for Enrollees With Multiple Medicaid Identification Numbers
Learn how the AI-generated research projects were createdOverall Conclusion
The OIG concluded that Pennsylvania made unallowable capitation payments totaling at least $8,784,549 ($4,596,390 Federal share) for enrollees with multiple Medicaid ID numbers during the audit period (January 1, 2019 – December 31, 2022). The unallowable payments were caused by insufficient controls to detect or prevent duplicate Medicaid IDs, and the state agency’s match-scoring algorithm and related processes did not reliably prevent multiple IDs from being assigned. Five recommendations were issued to refund the Federal share and to improve monitoring, data quality, and safeguards.

Audit Scope
Audit covered Medicaid capitation payments made by the Pennsylvania Department of Human Services to Managed Care Organizations (MCOs) from January 1, 2019 through December 31, 2022, focusing on 3,584 enrollee-matches where an individual had more than one Medicaid ID number. The detailed sampling involved a stratified random sample of 100 enrollee-matches from a frame comprising 32,867 individual capitation payments totaling $19,846,784 ($10,390,232 Federal share). The audit did not review the State agency’s entire internal control structure beyond controls related to preventing or detecting duplicate IDs; the objective was to determine if unallowable capitation payments were made as a result of multiple IDs and to estimate the total and Federal share of such overpayments.
Key Findings Summary
In a sample of 100 enrollee-matches, 2 enrollee-matches were paid correctly, while 98 enrollee-matches resulted in unallowable capitation payments totaling $1,068,308 ($559,087 Federal share).
The unallowable payments occurred because the State agency’s controls were insufficient to detect or prevent multiple Medicaid ID numbers from being assigned to the same enrollee.
Based on the sample results, the State agency made unallowable capitation payments totaling at least $8,784,549 ($4,596,390 Federal share) during the audit period.

AI Scope Summary
The audit aimed to determine whether Pennsylvania’s DHS made unallowable capitation payments to MCOs due to enrollees having multiple Medicaid IDs, estimate the monetary impact, assess existing controls, and propose corrective actions.
AI-Generated Insight
This audit highlights vulnerabilities in Medicaid ID management and data integrity that can lead to significant Federal overpayments. Strengthening the file clearance process, refining the match-scoring algorithm, consistently using the Zero SSN report, and implementing ongoing testing and training are critical to prevent duplicate IDs, ensure accurate capitation payments, and protect Federal funds.
