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

Coding a Composite Graft with Harvested Cartilage

Question:

I performed a composite graft (CPT 15760), and harvested cartilage from the ear.  Can I report for the harvesting?  If yes, what code do I use?

Answer:

You can report both 15760 (Graft; composite (eg, full thickness of external ear or nasal ala), including primary closure, donor area) and CPT 15040 (Harvest of skin for tissue cultured skin autograft, 100 sq cm or less) for harvesting the graft.  These two codes are not bundled under the National Correct Coding Initiative and can be reported together.

Removal of Mandibular Implant

Question:

We are removing old plates from the right and left mandible. It is ok to use 20680 x 2?

Answer:

There was just a CPT Assistant about this in January 2018. CPT 20680 (Removal of implant; deep (eg, buried wire, pin, screw, metal band, nail, rod or plate)) may be reported twice for removal of implants from noncontiguous sites on the same bone, such as the mandible, if separate incisions are made.  However, use 20680 only once if one incision is made to remove bilateral implants from the same bone such as the maxilla.

Fat Grafting with a Breast Revision

Question:

My doctor reports a breast revision with CPT codes 19380 and 20926 on the same breast.  Can we report the fat graft harvest in addition to the revision?

Answer:

CPT code 19380, Revision of reconstructed breast involves revising an already reconstructed breast. The code includes repositioning the breast; making adjustments to the inframammary crease; making capsular adjustments; and performing scar revisions, fat grafting, liposuction, and so on. Therefore, it is not appropriate to report the fat graft harvest with CPT 20926 as it is included in the procedure.

Removal of Tissue Expander in the Office

Question:

I have a question on tissue expander coding. How would I code for an in office procedure on a tissue expander removal under local anesthesia? The patient had breast cancer and the mastectomy was performed at a different facility. The patient’s tissue expander became exposed so the expander was removed at my facility in the office. I was trying to find some coding guidelines on this scenario. Any help you can give me would be greatly appreciated!

Answer:

The CPT code for removing a tissue expander in the office is the same as it is if the TE was removed in the hospital – the physician reports 11971 (Removal of tissue expander(s) without insertion of prosthesis). Medicare’s payment for the physician in the office (place of service 11) is somewhat higher than the payment in the OR (place of service 24, 22, 21).
