Medical Coding

“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.”

“What code would you recommend for the excision of a pressure ulcer? Here is an excerpt from the operative report: “Attention was directed to the left plantar medical foot at the level of the arch where an approximately 3 cm round chronic ulceration with underlying bursa formation was noted. At this time, an elliptical incision was made in a 3:1 fashion running in line with the foot from toe to heel. This incision was deepened through subcutaneous tissues with care being taken to identify and retract all vital neurovascular structures. At this time, dissection scissors were utilized in order to remove the chronic ulceration with underlying bursa. The skin margins were then separated in order to free up and allow for skin closure.”

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.

"An in-patient consultation was done and later on the same day an in-patient surgical procedure was performed. Medicare has paid for the consultation code but has denied payment for the procedure stating that “a CPT or a CPT/modifier combo is not compatible with another procedure or CPT/modifier combo provided on the same day according to the CCI.” The codes used were CPT 99222 and CPT 28820 (T6). Any suggestions?”

“I am trying to educate my physician about the documentation requirements for CPT 11721. He doesn’t think it’s important to document the number of nails debrided or even the method of debridement. Is there a resource you can point me to that specifically addresses this?” This was addressed last week. “Since it is stated – CPT 11721: Debridement of nail(s) by any method(s); 6 or more, why would it be necessary to document what instruments were used for debridement since any method would be accepted under this description?” This is part 2.
