Medical Billing

“I have a rheumatoid patient with a grossly deformed interphalangeal joint with significant osseous malformations leading to a chronic ingrown toenail on the hallux fibular border. I have ruled out any infection, osteomyelitis, or neoplasm. The bone is grossly hypertrophic and needs excision along with the nail structures on the fibular border. There also may need to be some plastic closure performed. What are the appropriate ICD10 and CPT codes reflective of this scenario?”

“I have been getting denials from BCBS, First Care, Aetna, and UHC on claims billed out with diagnosis codes M72.2, M71.571, M71.572, M77.31, and M77.32. Has anyone else had this problem lately? The NDC number and the description are on the claim. The claim is going out as follows: CPT 99213 25, CPT 20550 RT, CPT 20550 LT, J0702 x 2 units, J1030 x 2 units.”

“I’m trying to determine the coverage of diabetic shoes for a patient who has had one foot/leg amputated. Somewhere in my brain I seem to remember that Medicare will cover a pair of shoes so the amputee can wear the shoe on his prosthetic. Does this also apply to heat moldable inserts? Can we dispense them for the shoe that will be used on the prosthetic leg? I would appreciate any thoughts on this situation. I have read the LCD and associated article but can’t seem to fully understand how this works.”

“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?"
