Coding

“I had a patient present to the clinic with multiple, minimally displaced toe fractures. She has Medicare and we are planning to treat all four of these conservatively. When and how do I use CPT code 28510?”

“I have several healthy Medicare patients that have painful calluses. These patients come to my office, sometimes monthly complaining of painful callouses. I understand that Medicare does not cover the routine trimming of calluses in healthy patients. However, I have been billing CPT 99212-13 with the diagnosis codes of L84 (corns and callous), M77.4X (metatarsalgia). The documented management plan for L84 is discussion of moisturizing the feet, not waking barefoot, etc. and then I debride the callus. The documented management plan for metatarsalgia is discussion of metatarsalgia and surgical options, and then I place felt padding in the shoe, or modify the shoe to take pressure off the callus. My patients rarely follow my advice for moisturizing and not going barefoot; so ultimately, the calluses come back. Is this appropriate billing? The treatment I provide is instrumental in preventing a wound or ulceration from occurring (which I also document). Also, it relieves the patient of pain. Is it appropriate to bill an E/M code in lieu of a procedure code if the procedure is not covered?”

“I am having trouble finding an appropriate code to bill for a procedure to remove tophaceous material at a toe. The location was the left 2nd toe. This was performed in the office and a digital block was utilized to obtain anesthesia at the toe. Using a 3mm dermal curette, approximately 1 mL of tophaceous material was removed and a sterile gauze dressing applied. I planned to use ICD-10 M1A-0721. What CPT would be appropriate in this situation?”

“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.

“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.”

“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?”

“I am curious when and how to bill G0127 or G0247 instead of CPT code 11721 when performing Routine Foot Care.”

“I recently saw a new patient with Oxford insurance for a tinea problem. A prescription was given and options for additional treatments were discussed. We billed his insurance for an initial office visit. The visit was allowed by insurance and the payment was applied to his deductible. He was billed by us. He checked with Oxford and is now telling us that “preventive” care is not subject to the deductible and would like me to resubmit to Oxford telling them that the visit was for “preventive” care. My opinion is that “preventive” care does not really apply to a specialist and that I could not undo what I already submitted. Can we bill for “preventive” care and, if so, is it possible to resubmit the claim?”
