Medical Billing

“Is the debridement of a plantar keratosis (CPT 11055) at the first metatarsal head considered bundled with nail debridement (CPT 11720)?”

“I have a patient who has Blue Cross insurance. He came in for a matrixectomy on February 8th and returned on February 15th for follow up. I billed CPT 99213 using M79.673 and T81.40XA for the follow up and the claim was denied. Is there another code or modifier that I should include?”

“What would be the best code or codes to represent an acute, ruptured plantar fascia?"

“My partner prefers to inject the subtalar joint under fluoroscopy. What would be the best procedure code to bill for an injection of the subtalar joint and does the use of fluoroscopy change things?”

“For Medicare, it has been well established that debridement for callouses is not covered when class findings are not present. But what about that patient that complains of pain from a callus. If you evaluate the painful callus and manage the painful callus, would it not be appropriate to bill a low level E/M code? This patient does not want surgery but this is a recurring problem. Can the E/M be billed each time the patient is seen?”

“What procedure codes represent the treatment of an abrasion? Are we restricted to E/M codes?”

“I am part of a recovery audit from CMS for using a modifier 59. Cotiviti Healthcare has been hired by CMS to review my use of modifier 59. They stated that my operative report supports documented Charcot reconstruction and the use of application of external fixator (CPT 20692) but modifier 59 was inappropriately used since both procedures were performed at the same session. Should I have used a different modifier in this situation? Is application of an external fixator (CPT 20692) not considered a separate procedure if it is performed at the same session as other reconstruction procedures?"

“Is a plantar keratosis debridement (CPT 11055) at the first metatarsal head considered bundled with nail debridement (CPT 11720)?”

“In the summer of 2021, when the delta variant was near its peak, I attempted a house call visit to review laboratory results and discuss treatment options. The family of the elderly patient did not want anyone in the house and recommended leaving the results and instructions at the front door. Lab results, my interpretation of the results, prescription and instructions were left at the front door as instructed. This, of course, required driving to the patient’s residence to accomplish this. How could this scenario be billed to Medicare?”

“A Medicare patient is admitted to the hospital for a foot infection and suspected osteomyelitis of the left, fourth toe. Amputation of the toe is done at the metatarsophalangeal level and billed CPT 28820-T3. However, post-operative x-rays reveal that there is residual bone, presumably from the base of the proximal phalanx that remains. The patient is taken back to surgery a few days later for removal of the residual bone. This was done during the same hospitalization. Would this be coded as CPT 28124-78? Would the -78 modifier not apply since there is no global for the amputation? Could CPT 28124 be billed without a modifier?”
