Medical Billing

Based upon an article that is posted within The American Institute of Healthcare Compliance website, it is important to note that the OIG is Auditing for Abusive Dermatology Claims. The Office of the Inspector General (OIG) is auditing dermatologists for billing an E/M service on the same date of service that a minor surgical procedure (ie. postoperative global period of 0 or 10 days) is performed. Medicare only covers Evaluation & Management (E/M) services on the same day as a minor procedure if a physician/surgeon performs a significant and separately identifiable E/M service that is unrelated to the decision to perform the minor surgical procedure. In order to bypass the CCI edits or the Correct Coding Initiative edits and bill for the E/M service and the minor surgical procedure/CPT code on the same date of service, the 25 modifier needs to be appended to the E/M service.

“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?”

“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?”

“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.”

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

“Here’s the scenario: patient has a chronic ulcer left foot that comes in for regular debridements/wound care. Two weeks ago he has a full thickness ulcer and osteomyelitis at the 2nd toe right foot and I performed a partial amputation of the toe in the office. He comes in for postop check five days later and everything is fine. At his 2nd postoperative visit, I notice a new punctate ulcer plantar 2nd toe with exposed bone and progressing osteomyelitis. I did a prep and debrided the bone at this visit (Yes, authorization was submitted for a more proximal amputation at a future appointment.) I also debrided the wound on his left foot. The question I have is with a multiple modifier order/rule for the debridedment of the ulcer left foot. I billed the visit out as follows: CPT 11044-78,T6 CPT 11042-59,79,LT Should the order of the modifiers with the CPT 11042 be -59,79 or -79,59 (or does this matter?) I have seen coding recommendations that say that the 1st modifier should be the “pricing” modifier and the 2nd modifier should be the “procedure” modifier but I am not sure of this.”
