Medicare and Orthotics

by Dr. Michael Warshaw, DPM, CPC

“I read the Medicare DME requirements for diabetic shoes and inserts. I am still confused and am seeking clarity. I know for diabetic shoes, it requires a MD/DO to certify that patient has diabetes with neuropathy and thus, qualifies for diabetic shoes and 3 custom insoles. It is my understanding that Medicare only covers orthotics if the patient is diabetic and as stated above, is certified to have diabetes with neuropathy. I have seen other physicians use the KX modifier to get orthotics incorrectly paid. My question is: If I just want to dispense the custom molded diabetic insoles (three pairs of orthotics/diabetic insoles as allowed by Medicare — and not the shoes), are there separate rules or are they the same rules? Is it legal to do a cash pay for diabetic/soft custom insoles? Any other tips you have found useful in your practice? Have you in your practice just dispensed the insoles and not the shoes?”

Follow Up for a Fracture

by Dr. Michael Warshaw, DPM, CPC

​​​​​​​“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?”

Reading X-rays from an Outside Source

by Dr. Michael Warshaw, DPM, CPC

“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?”

Diabetic Shoes

by Dr. Michael Warshaw, DPM, CPC

“I documented a women’s size 10.5 shoe measurement in my Medicare note and then ordered the shoes from my diabetic shoe supplier. The supplier mailed me a pair of men’s 8.5 shoes since they are essentially the same size as a woman’s 10.5. In an audit, would Medicare have a problem with the size discrepancy, since I have to document that I dispensed a men’s 8.5 rather than the originally fitted women’s 10.5?”

Emergency Service

by Dr. Michael Warshaw, DPM, CPC

“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?”

Multiple Fractures of the Toe

by Dr. Michael Warshaw, DPM, CPC

“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?”

Stable, Chronic vs. Chronic With Exacerbation/Progression

by Dr. Michael Warshaw, DPM, CPC

“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?”

Fracture Care Global

by Dr. Michael Warshaw, DPM, CPC

“What is the date that fracture care begins? Is it the date of the injury or is it the date of service when the doctor makes the decision for closed management of a fracture?”

Multiple Ingrown Nail Surgeries

by Dr. Michael Warshaw, DPM, CPC

“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?”

Annual Diabetic Foot Exams

by Dr. Michael Warshaw, DPM, CPC

“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?”
