Clip and save your modifier 25 use checklist Easily distinguish a significantly separate E/M service from a minor related E/M that's included in a procedure with this handy tool. You don't have to sacrifice E/M service pay just to keep your practice in the clear from payers that are scrutinizing claims containing modifier 25. Instead, confidently label a service as separate and significant using this checklist provided by Denae M. Merrill, CPC-E/M, owner of Merrill Medical Management in Saginaw Mich. Before using modifier 25, ask four questions: 1. Why is the patient being seen? Are there signs, symptoms and/or conditions the provider must address before deciding to perform a procedure or service? 2. Was the provider's evaluation and management of the presenting problem significant and beyond normal preoperative and postoperative work? 3. Was the procedure or service scheduled in advance of the patient encounter? 4. Is there more than one diagnosis present that the provider addressed and/or affecting the treatment and outcome? Tip: Supporting separate documentation of the E/M service and the procedure is helpful when justifying the E/M-25 service. Don't bury the E/M documentation in the procedure note.
