Coverage under prefix ELM

PPO

This prefix is associated with a PPO plan. Preferred Provider Organization coverage gives members flexibility to see specialists without referrals and to use out-of-network providers at higher cost-sharing. Claims can be submitted for both in-network and out-of-network services, though reimbursement rates differ.

Traditional Indemnity

Traditional indemnity coverage under this prefix is a fee-for-service plan. Members can see any provider without network restrictions or referral requirements. The plan reimburses a set percentage of usual and customary charges. Claims are submitted directly to the payer listed above.

HDHP

This prefix is associated with a High-Deductible Health Plan. HDHP members pay more out-of-pocket before insurance coverage begins. These plans are commonly paired with HSA or HRA accounts. When billing, be aware that the member may have significant cost-sharing responsibility until their annual deductible is satisfied.
