Atherosclerosis

“On all of our patients that qualify for routine foot care with the diagnosis of I70.203 Atherosclerosis we send an “Atherosclerosis Letter” to the patient’s treating doctor with our findings and ask them to sign if they agree with our findings. 99% of the time the doctors send the letter back signed. We have always done this in accordance with the routine foot care LCD that in the past stated that we had that letter or documentation from the treating physician in our patient’s chart “in a timely manner.” Recently we have had some doctors sending back the letter, disagreeing with our findings. We have already billed the services from their initial visit knowing or thinking that we will have that documentation for the next appointment in 9 weeks. This led me to research the LCD again, and I am unable to locate the verbiage that was used before about the patient’s other treating doctors agreeing and signing anything. It merely states that we have our findings in the note and the other doctor’s name on the claim to Medicare. Do we need that letter agreed to and signed from the patient’s other doctor? Do other offices also send this “letter” to get that info? Any input is greatly appreciated.”
