Division and Inset of Flap

Question:

A patient presents for division and inset of a neck-to-ear pedicle flap.  Should we report 15620 or 15630?

Answer:

The CPT codes reported for the division and inset are chosen by the permanent inset site, not the donor site.  So in your case, CPT code 15630 (Delay of flap or sectioning of flap at eyelids, nose,ears, or lips) would be reported, not 15620 (Delay of flap or sectioning of flap at forehead, cheeks, chin,neck, axillae, genitalia, hands, or feet).

Sentinel Node Identification

Question:

We have a new plastic surgeon and he’s doing a procedure my other guys don’t perform.  The patient goes to radiology for injection of radioactive isotopes then to the operating room where my plastic surgeon excises the skin cancer and then injects blue dye and uses a gamma probe to identify a sentinel node.  Then he excises the sentinel node.  I’ve never coded lymph node procedures before – help!

Answer:

It’s always fun to learn something new, isn’t it!  For the lymph node removal procedure, look at codes 38500 – 38531 to see which code best matches the procedure he did.  Then you can also report +38900 (Intraoperative identification (eg, mapping) of sentinel lymph node(s) includes injection of non-radioactive dye, when performed (List separately in addition to code for primary procedure)). CPT +38900 covers the intraoperative injection and use of the gamma probe to identify the sentinel lymph node.

Botox for Migraine Headaches

Question:

When you inject Botox for migraine headaches, can you bill the injection code more than one time? We normally go about this as a cosmetic procedure, but I just wanted to look into this to see if I could bill out CPT code 64615 for each muscle group that is injected?

Answer:

The CPT language is very clear that all four muscle groups, on both sides, must be injected for a total of 8 injections. CPT 64615 states Chemodenervation of muscle(s); muscle(s) innervated by facial, trigeminal, cervical spinal and accessory nerves, bilateral (eg, for chronic migraine).  In your scenario, you will use 64615 and bill as 1 unit.

Diagnosis Code for Post Op Visits

Question:

What’s the best way to do the diagnosis coding for postop visits? I mean, does it really matter since we aren’t billing for a visit?

Answer:

Yes, it is important to accurately code the diagnosis. The ICD-10-CM guidelines for postop/aftercare include the following:

1. If the original diagnosis is trauma (eg, using an S diagnosis code)ora code that requires a 7^thcharacter (eg, M80-): then you’ll continue to use the original diagnosis code but you’ll change the 7^thcharacter to one which includes “subsequent encounter”.  For example, a finger fracture – when you fixed the fracture in surgery you used a diagnosis code with a 7th character of, say, A (initial encounter, closed fracture).  So for your postop visits (CPT 99024), you’ll use the same finger fracture diagnosis code but with a 7^thcharacter of, say, D (subsequent encounter, routine healing).

2. For non-trauma diagnoses (and those that do not require a 7^thcharacter): Now you’ll switch to a Z code when you’re using CPT 99024.  Look at the Z48.- codes…there are several that can be used such as:

Z48.00   Encounter for change or removal of nonsurgical wound dressing

Z48.01   Encounter for change or removal of surgical wound dressing

Z48.02   Encounter for removal of sutures (or staples)

Z48.03   Encounter for removal of drains

Post Op Hemorrhage Repair: Is it Billable?

Question:

Can I bill for taking the patient back to the OR to explore and repair post-op hemorrhage on day 3 post-op? I heard that all complications are included in the payment of the original surgery.

Answer:

Yes, you may bill for this.   CPT and Medicare agree that taking the patient back to the OR to treat a complication is billable. Modifier 78 (unplanned return to the OR) is appended to the procedure code(s) performed to treat the hemorrhage.  The appropriate ICD-10-CM code for a postoperative hemorrhage would also be reported.

Diagnosis Code for a Scar Contracture

Question:

What ICD-10-CM diagnosis code do I report for a patient seen for a release of scar contracture of the flexor surface of the left elbow after healing of a third degree burn?

Answer:

You would report L90.5 (scar conditions and fibrosis of the skin) and T22.322S

(Burn of third degree of left elbow, sequela).  The condition you are treating is listed first with the sequela (late effect) reported as the secondary diagnosis.
