Charlotte L. Kohler, RN, CPA, CVA, CRCE-I, CPC, ACS, CHBC, discusses how modifiers -59 and -91 differ and what coders need to know to use them when reporting laboratory services.
Q: What if the provider states that diabetes is due to the adverse effects of a drug, but doesn't tell us which drug? How do we report that in ICD-10-CM?
Q: How does CPT ® define "final examination" for code 99238 (hospital discharge day management; 30 minutes or less)? Does the dictation have to include an actual detailed examination of the patient? We have been coding 99238 for discharges that include final diagnosis, history of present illness, and hospital course along with discharge labs, medicines, and home instructions. Very few contain an actual exam of the patient. Have we been miscoding all this time?
Q: I have a question regarding a National Correct Coding Initiative (NCCI) edit. I reported CPT ® code 80053 (comprehensive metabolic panel) and 84132 (potassium; serum, plasma or whole blood), resulting in an NCCI conflict. This code pair does allow modifier -59 (distinct procedural service) to be appended to one of the codes to be paid for both tests. Does it matter if we append modifier -59 to the primary code or the secondary?\ In my case, sometimes the secondary code is already dropped into the system and now the edit is asking me to append the modifier. Can I add modifier -59 to 80053 whether it's the primary code or not?
Q: A patient arrives at the interventional radiology department to have an inferior vena cava (IVC) filter inserted for portal hypertension and an iliac stent for May-Thurner syndrome. The physician is unsuccessful in accessing an appropriate portal vein branch, despite a few attempts to pass a wire into small portal branches, and aborts the placement. The plan is to reschedule and return with a transplenic approach. Do we code the attempted IVC filter placement with modifier -74 (discontinued outpatient procedure after anesthesia administered) and the complete iliac stent procedure? Or do we code the extent of the IVC filter placement (that being venography) with the complete procedure? Or do we only code the completed procedure?
Coders can run into two types of edits that may require them to append modifier -59 (distinct procedural service) to override: National Correct Coding Initiative (NCCI) edits and medically unlikely edits (MUE). Sarah L. Goodman, MBA, CHCAF, CPC-H, CCP, FCS, and Susan E. Garrison, CHCA, CHCAS, CCS-P, CHC, PCS, FCS, CPAR, CPC, CPC-H, explain the differences between the edits and how to correctly determine when to override the edit.
QUESTION: When would you use the table labeled as not otherwise classified drugs at the end of the HCPCS Level II Table of Drugs and Biologicals? Many other drugs are not assigned a HCPCS code and are not in this table.
Q: A patient received Toradol 30 mg IV and Zofran 4 mg IV at 14:38. He also had normal saline wide open with documented start of 14:30 and stop of 15:40. Is the hydration chargeable as 96361 (intravenous infusion, hydration; each additional hour) even though the initial service is not 90 minutes? Is the hydration a concurrent service?
Providers have to create their own ED E/M guidelines, which can present a variety of challenges for facilities. For coders, this means an understanding of how to calculate critical care and other factors in order to report the correct visit level.
