READER QUESTIONS:
Look to Distinction for Modifiers 25, 59
Published on Tue Jan 26, 2010
Question:
When appending modifiers with E/M service during a pulmonary function test (PFT), I'm not sure which one to add to the pulmonary function code: modifier 25 or modifier 59? Please help. Illinois Subscriber
Answer:
These two modifiers can really get confusing, but all is not lost. Just focus on the main difference between modifiers 25 (
Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) and 59 (
Distinct procedural service).
Explanation:
According to CPT's very own clarification, you should use modifier 59 only to distinguish one procedure from another procedure. For example, if you bill for a six minute walk test and spirometry, you would add modifier 59 to the spirometry (code it as 94620,
Pulmonary stress testing; simple [e.g., 6-minute walk test, prolonged exercise test for bronchospasm with pre- and post- spirometry and oximetry], 94010-59) because of a CCI edit that includes spirometry as a component of the walk test. When you're billing a PFT and an E/M, modifier 25 is not a requirement. However, be careful as some third-party payers actually demand its inclusion. Typically, modifier 25 is used to indicate you have documentation that supports an E/M as a significant and separate service from the work involved in another service or procedure. For example, if the patient underwent bronchoscopy after the decision was made during a subsequent hospital visit performed on the same day, you would add modifier 25 to the subsequent hospital visit code (99232-25,
Subsequent hospital care, per day, for the evaluation and management of a patient, which requires at least 2 of these 3 key components: an expanded problem focused interval history; an expanded problem focused examination; medical decision making of moderate complexity...; 31622,
Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; diagnostic, with cell washing, when performed [separate procedure].
This indicates that the hospital visit was for a reason other than to explain the bronchoscopy procedure, or perform the required preprocedural H&P.
