I49.02: Ventricular flutter
I49.02, ventricular flutter, is listed as a covered diagnosis in 11 Medicare billing and coding articles that apply to 43 HCPCS Level II codes, including J0153 (Injection, adenosine, 1 mg (not to be used to report any…), J1250 (Injection, dobutamine hydrochloride, per 250 mg), J1245 (Injection, dipyridamole, per 10 mg). 5 of these codes have a 2026 DMEPOS fee schedule amount; K0606 pays $3,588.90 (RR) depending on the state. The articles come from 5 Medicare contractors. A listed diagnosis supports medical necessity only; coverage still depends on the LCD's criteria and on documentation in the medical record.
