HCPCS Modifier EY
No physician or other licensed health care provider ordered an item or service.
Guidelines and Instructions
- This modifier is purely informational for Medicare use and may be submitted with all HCPCS and CPT codes
- When supplies are provided by DMEPOS suppliers without a physician's order, these suppliers should submit HCPCS modifier EY on each line item on the claim and National Provider Identifier (NPI) in the Ordering/Referring Provider Name fields on claims submitted on or after May 23, 2008, to secure a Medicare denial
- Because this modifier is informational only, submit this modifier in the last modifier position, after any other appropriate modifiers
