Can anyone please help me with the billing of home sleep studies. My physician reads these studies in the outpatient department of the hospital. I have tried billing 95806/26 with a place of service as outpatient and medicare is denying stating treatment deemed by payer as rendered in unappropriate/invalide place of service. I have also tried G0399/26 with a place of service as outpatient and this is also being rejected stating unappropriate/invalid place of service. Does this need to be billed as patient's home even though physician is reading these in an outpatient setting?
