Codes 20560 and 20561 are the new codes for DN and should be used even though they are not reimbursed by Medicare and essentially all commercial carriers. I would no longer bill MT for it even thought the APTA sites DN under MT in clinical practice guidelines. Cash payment is the best way to go and yes an ABN can be used for Medicare patients since medicare is clear they do not reimburse for it. I would consult your billing dept. at the hospital as I have been only in private practice and hospital billing may be different.
