Coding

“On February 11, a patient has a transmetatarsal amputation. The patient is a non-compliant, diabetic. The site deteriorates weeks after he leaves the hospital. On March 24, he was readmitted for an infected at the amputation site. On March 26, the remaining 5 metatarsals stumps are removed, and the wound is kept open. How would you recommend coding for the 2nd surgery? What is the code for removing the 5 remaining metatarsal stumps?”

"An in-patient consultation was done and later on the same day an in-patient surgical procedure was performed. Medicare has paid for the consultation code but has denied payment for the procedure stating that “a CPT or a CPT/modifier combo is not compatible with another procedure or CPT/modifier combo provided on the same day according to the CCI.” The codes used were CPT 99222 and CPT 28820 (T6). Any suggestions?”

“I am trying to educate my physician about the documentation requirements for CPT 11721. He doesn’t think it’s important to document the number of nails debrided or even the method of debridement. Is there a resource you can point me to that specifically addresses this?” This was addressed last week. “Since it is stated – CPT 11721: Debridement of nail(s) by any method(s); 6 or more, why would it be necessary to document what instruments were used for debridement since any method would be accepted under this description?” This is part 2.

I am trying to educate my physician about the documentation requirements for CPT code 11721. He doesn’t think it’s important to document the number of nails debrided or even the method of debridement. Is there a resource you can point me to that specifically addresses this?

“If a patient refuses to pay their bill due to a high deductible, is it possible to request the insurance company (i.e. Anthem) to delete the claim? That way, the patient will still be responsible for paying their deductible amount elsewhere.”

“I have great difficulty getting paid for CPT 28308 when a hammer toe repair is performed at the same time. The billing scenario generally will look like this: CPT 28308 (2nd metatarsal osteotomy) -RT CPT 28285 (2nd hammertoe repair) -T1 -59 We never get paid for CPT 28308 in this scenario. Does anyone have any suggestions? We link the acquired deformity of bone diagnosis to CPT 28308.”

Under reciprocal billing arrangements, a patient’s absentee physician may submit a claim and receive payment for services arranged to be provided by a substitute physician on an occasional basis. The regular physician should identify the service as substitute physician services and bill with the Q5 modifier (service furnished by a substitute physician under a reciprocal billing arrangement).

“Can you evaluate and manage onychomycosis without debridement for the purpose of treating onychomycosis for an established patient? This would be in the absence of pain and underlying conditions, specifically with Medicare patients. Is it a covered condition for just evaluation and management? Would tinea pedis be covered as a sole diagnosis for evaluation and management?”

“We have had more than one claim where Blue Cross Blue Shield of Oklahoma is paying for CPT 28122 but denying CPT 28306, despite the use of the 59 modifier. Our question is why wouldn’t CPT 28306 be allowed instead of CPT 28122 as it is far more work? We are trying to determine how to appeal this.”

“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?”
