Frequently Asked Questions
How does workers' compensation billing differ from standard medical billing?
Workers' comp billing requires strict state compliance, specialized injury reporting, treatment pre-authorization, and billing according to state-mandated fee schedules rather than standard health insurance rules.
Why are workers' compensation claims frequently delayed?
Delays typically occur due to incomplete medical documentation, missing treatment pre-authorization, improper medical coding, or slow responses during utilization review by the claims administrator.
What happens when a workers' compensation bill is underpaid?
If an insurance carrier underpays a claim, billing specialists submit a Second Bill Review (SBR). If the dispute remains unresolved, the team can initiate an Independent Bill Review (IBR) or file Workers' Compensation Lien Collections with the WCAB.
Why is lien management important for California providers?
In California, unpaid medical balances can be secured as liens. Effective lien collection ensures practices recover full reimbursement for legitimate medical care provided to injured workers, even when cases involve lengthy legal disputes.
