I have received a phsychiatric reduction from Medicare due to diagnosis 305.1 (tobacco abuse). I sent a redetermination to have the diagnosis codes re-sequenced with 305.1 to be last. They reprocessed the claim, removed the psychiatric reduction, but reduced the allowed amount to the psychiatric allowable! Therefore, no additional payment was made. They are telling me that because the diagnosis is on the claim, (regardless of sequencing) we will be paid at the psychiatric rate! Any advice??
