Medical Coding

“I performed a removal of a failed 1st metatarsophalangeal implant and, at the same setting, an arthrodesis. Should I bill for both the removal of the implant and subsequent fusion?”

​​​​​​​“I saw a patient on March 20, 2020 with a new, mildly displaced 3rd metatarsal fracture (S92.332A). I have been following him since then and have billed Anthem Blue Cross with ICD10 S92.331D and have gotten reimbursed. The last visit I had with the patient was August 17, 2020 and billed Anthem Blue Cross for S92.332S. The claim was denied as Missing/incomplete/invalid principal diagnosis. Isn’t S92.332S a valid primary diagnosis code?”

“We have a disagreement among our group regarding radiology billing. If a new patient presents with x-rays, MRI, etc., from an outside source, without a report (or with an inadequate report), can the podiatrist bill for the professional component of reading the imaging studies provided?”

“I had a patient call me worried about a possible diabetic foot infection. The patient has a history of below the knee amputation at the other limb and was panicked about the potential loss of limb. I worked them into the schedule that day and I am thinking about coding CPT 99058 in addition to the E/M code. Can I get paid for CPT 99058 and does it matter if the potential “infection” turned out to be not infected?”

“My patient suffered blunt trauma to his right hallux and suffered non-displaced fractures of the distal and proximal phalanx. We are going to treat this injury conservatively. Would it be appropriate to bill CPT 28490 two times to represent the treatment of both phalanx?”

“As a general question, I am wondering if a physician documents that the patient has had symptoms for longer than a year and has failed conservative/other treatment, can this problem be considered as “chronic with exacerbation/progression”? I am referring to the verbiage in the CPT book (page 13, under Stable, chronic illness) regarding the expected duration of at least 1 year and am wondering if it is applicable in this scenario. Also, I know that a diagnosis of osteoarthritis is inherently considered “chronic”, but I am wondering if there are other diagnoses that can be considered ‘chronic’, as well?”

“Outpatient surgery was performed at a surgical center. We billed Blue Cross for CPT 11750 (T5) and CPT 11730 x 3 (T2, T7, T9). But they only paid CPT 11750. And the denial reasons are: ARV – Quantity billed exceeds CMS medically unlikely edits (MUE) limit. Rebill within MUE limit if appropriate. 222 – Exceeds the contracted maximum number of hours/days/units by this provider for this period. This is not patient specific. Usage: refer to the 835 healthcare policy identification segment, if present. So my question is, what is the limit to bill for ingrown nail surgery?”

“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?”

“Since the global period for a toe amputation is now zero days, does that mean I bill for removing sutures in the office when I do a follow up visit in 14 days? Billing for this, seems very uncomfortable to me.”
