“We are inquiring about the use of the Q7 modifier when billing nail and callus debridement with Medicare. We are aware of the changes to the LCD with diagnosis codes. When billing nail debridement CPT 11721 and callus debridement CPT 11056, we are submitting diagnosis codes Z89.412 and Z89.422, (acquired absence of toe) with a Q7 modifier to show “non-traumatic amputation of a foot or an integral skeletal part of the foot.” Now we are being told by Medicare that per the LCD, we cannot bill those diagnosis codes even with a Q7 modifier. Should we be billing with a different modifier?”
When you have a Business Associate Agreement in place you always can send a letter terminating the relationship. When you send that letter, you should instruct the Business Associate to delete all your patient data, and if that is not feasible that hey are responsible to protect that data under the HIPAA regulations. It is always best to have an attorney review the letter prior to sending it.
