Wiki Mod 51 vs Mod 59 for ASC use

Create Wiki
Not according to the current CPT book. In Appendix A, under 'Modifiers Approved for Ambulatory Surgery Center (ASC) Hospital Outpatient Use,' -51 is not listed. However every payer is different - I haven't come across one in 10+ years but there may be payers out there that want -51's on ASC claims.
 
Modifier 51

This is what I found on a Billing website................


What is Modifier -51 and when to use?


When and How Do I Use Modifier -51? What is Modifier -51 anyway?

Modifier -51, Multiple Procedures

This modifier is used when reporting multiple procedures performed by the same physician on the
same day. Do not use this modifier for "add-on" codes (see appendix D of the CPT Code book). Do
not use this modifier for codes with "modifier -51 exempt" symbol (see appendix E of the CPT Code
book). Do not use this modifier with an E/M code. This modifier can only be used by the same
physician on the same day who performed the procedure.

Coding tip: List the highest reimbursable code (after the main procedure code) based on the fee
schedule.
