T82.198A: Other mechanical complication of other cardiac electronic device, initial encounter

T82.198A, other mechanical complication of other cardiac electronic device, initial encounter, is listed as a covered diagnosis in 8 Medicare billing and coding articles that apply to 34 HCPCS Level II codes, including C8925 (Transesophageal echocardiography (tee) with contrast, or…), C8926 (Transesophageal echocardiography (tee) with contrast, or…), C8927 (Transesophageal echocardiography (tee) with contrast, or…). 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.
