Podiatry Coding & Billing Alert

Question: Our patient had an abscess on her leg that was treated several days ago. Today, the physician assistant just performed a dressing change. What is the correct procedure code for this? It was not for a burn. Can we bill two office visits on the same day? We reported 99214 twice for the same date of service but used different diagnoses and insurance paid one and denied the other.

Answer: First, you should look back at the original notes from when the doctor first treated the abscess to determine whether an incision and drainage was performed. If so, you are probably still falling under the I&D's 10-day global period, which means you can't charge anything.

If not, you'll simply report an office visit code (99212- 99213) if the physician assistant was examining the wound to ensure that it was healing well and then dressed it again afterward.

It depends on what the diagnoses were, but most insurers will not allow you to report two E/M services on the same date. These payers base their regulations on Medicare rules, which prohibit you from billing these together.

According to MLN Matters article MM4032, "Carriers MAY NOT pay two E/M office visits billed by a physician (or physician of the same specialty from the same group practice) for the same beneficiary on the same day unless the physician documents that the visits were for unrelated problems in the office or outpatient setting which could not be provided during the same encounter (e.g., office visit for blood pressure medication evaluation, followed five hours later by a visit for evaluation of leg pain following an accident)."

Private payers may follow this rule, or might make their own payment guidelines. It is always safe to be aware of payer specific guidelines on this and make your physician aware of this.

Some private payers may pay for the second E/M visit, billed with modifier 25 (Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service) when linked to a separate, distinct diagnosis. Alternately, it would also be appropriate to upcode to a higher level of E/M service, combining the E/M components of both visits. This must be carefully documented.
