Denial for abdominal ultrasound

[patdow]

Can someone please help us understand this denial meaning from Humana? The invoice is for an abdominal ultrasound and Doppler. ICD 10 code is K74.69 qnd K76.6. CPT is 93975 and 76700 with modifier 59.

Part of the denial letter is attached.

76700 is an inherent part of 93975-Duplex scan of arterial inflow and venous outflow of abdominal, pelvic, scrotal contents and/or retroperitoneal organs; complete study. Why are you billing the additional code of 76700? Do you have a redacted copy of the medical record that shows that 2 separate studies were done?
