Statewide Illinois Obstacles

Illinois Healthcare Billing Challenges We Solve

Challenge #01

Handling Local Code + Special Modifier Rules

The State of Illinois uses a set of program-specific local modifiers and codes for certain public health and community-based services. This results in high rejection rates due to local Code Requirements as many EHR Software do not support these codes natively, causing high front-end rejections. We at Shoreline Medical Billing company have mapped all these local codes into our EHRs so they route correctly and applies the custom modifiers and county-based billing rules. Our software flags codes that require special documentation or certification. And helps providers to achieve 95% of First Pass Acceptance Rates.

Challenge #02

Managing the Long Lag in Medicaid/MCO Response Times

Illinois Medicaid MCOs have some of the slowest appeal turnarounds, medical review updates and Provider enrollment confirmations. Providers must wait for 60–90 days for an appeal response from certain plans, compared to 30–45 days in other states. We at Shoreline Medical Billing company push appeals rigorously and track every pending review with internal timers. Providers can achieve faster payments across all six major Illinois MCOs by partnering with us.

Challenge #03

Prior Authorization Rules that Change at a County Level

Some programs in Illinois operates through county public health structures, and hence certain PA rules differ regionally. For example, the Cook County often has slightly different requirements compared to rural counties and the CountyCare has unique PA lists. This creates an inconsistency for a centralized billing team. We at Shoreline have built a county-specific PA rule engine that assigns PA tasks to a centralized team. This helps Providers to stop dealing with surprise denials tied to mismatched county PA rules.
