Coding Pearls

“Can one appropriately bill a debridement code, such as CPT 11042, each time when applying a skin substitute if indicated in a hospital, outpatient wound care clinic?”

“I think it is time for this topic to resurface. Being a coder/biller for a number of podiatrists around the U.S., I am finding that some are still scheduling “annual diabetic foot exams” as a routine on all of their diabetic patients. They are then performing a “full physical exam” and trying to bill an E/M. Sometimes this coincides with callus or nail treatment, at which time they want to add the 25 modifier. Of course, I am telling them that Medicare does not pay for an “annual diabetic foot exam” and that it is not a benefit and as such should be CASH. Has anything changed?”

“Has anyone else noticed Novitas is not approving E/M codes for treating onychomycosis medically? I saw a patient for evaluation of a discolored toenail. She was concerned it might be a fungal infection and wanted to treat the condition before it worsened. I obtained an H/P, a specimen for culture and discussed treatment options depending on culture results. I billed CPT 99212 with diagnosis code B35.1. The EOB read $0 payment. Code 49 “These are non-covered services because this is a routine exam or screening procedure done in conjunction with a routine exam. Any advice?”

“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?”

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 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?”

“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?”
