E/M During Global Period for Diabetic Foot Ulcer Following Total Metatarsal Amputation
If a patient has a total metatarsal amputation for diabetic foot ulcer and he gets readmitted for another condition, but then vascular surgery is consulted for his original underlying condition of DFA and now is treating the ulcer at the amputation site, 80 days post-op is the E/M billable? The TMA surgical wound is healing . The right plantar DFU stage 3 Wagner needs debridement and dressing changes.
Question:
If a patient has a total metatarsal amputation for diabetic foot ulcer and he gets readmitted for another condition, but then vascular surgery is consulted for his original underlying condition of DFA and now is treating the ulcer at the amputation site, 80 days post-op is the E/M billable? The TMA surgical wound is healing. The right plantar DFU stage 3 Wagner needs debridement and dressing changes.
Answer:
The evaluation and management service is not separately billable because it appears to represent continued management of the same surgical and disease process that prompted the original total metatarsal amputation. Any care directed toward the amputation wound or related diabetic ulceration in the same region during the 90-day global is included in the global period.

CPT 44130 “Separate Procedure” Designation
CPT 48150 describes a pancreatectomy, proximal subtotal with total duodenectomy, partial gastrectomy, choledochoenterostomy, and gastrojejunostomy, with pancreatojejunostomy. CPT 44130 describes an enteroenterostomy, an anastomosis of the intestine, with or without cutaneous enterostomy, and is designated by CPT as a “separate procedure.”
According to NCCI edits, there is a procedure-to-procedure (PTP) conflict between 44130 and 48150 when performed during the same encounter, which can be bypassed with modifier 59. If a provider routinely performs an enteroenterostomy in conjunction with the Whipple procedure to prevent future bile reflux—a common postoperative complication—is it appropriate to append modifier 59 to 44130?
Given that these procedures are frequently performed together, could the enteroenterostomy be considered an integral component of the Whipple procedure, rather than a distinct, independent, or unrelated service? While the Whipple procedure description does not specifically include an enteroenterostomy, it does involve bile redirection via choledochoenterostomy. The enteroenterostomy similarly aids in bile flow redirection, serving as an additional step to reduce bile reflux.
In light of this, should these procedures be routinely unbundled and billed together?

The enteroenterostomy similarly aids in bile flow redirection, serving as an additional step to reduce bile reflux.
In light of this, should these procedures be routinely unbundled and billed together?
Answer:
While modifier 59 can technically be used to bypass the NCCI edit between CPT 44130 and CPT 48150, it is not generally appropriate to routinely unbundle and report these codes together.
According to Medicare NCCI guidelines and CPT principles regarding “separate procedures,” CPT 44130 should only be reported when it is performed independently or is clearly distinct from other procedures. In the context of a Whipple procedure (CPT 48150), the enteroenterostomy is typically considered an integral part of the overall surgical approach, especially when performed to prevent bile reflux—a known complication.
CPT 48150 is the Column 1 (comprehensive) code, and CPT 44130 is the Column 2 (component) code. The “separate procedure” designation for 44130 indicates that it should not be reported in conjunction with a more extensive procedure unless it is truly separate and unrelated.
Therefore, unless there is clear documentation that the enteroenterostomy was performed for a distinct reason unrelated to the Whipple procedure, routinely appending modifier 59 to report both codes together would not align with coding guidelines.

KX Modifier?
Should the KX modifier be billed on all feminization procedures in the setting of gender dysphoria? For example, feminization rhinoplasty for a trans female patient assigned male at birth.
Question:
Should the KX modifier be billed on all feminization procedures in the setting of gender dysphoria? For example, feminization rhinoplasty for a trans female patient assigned male at birth.
Answer:
In the context of gender-affirming surgery, the KX modifier should be appended to procedure codes that are gender-specific—particularly when there is a mismatch between the patient’s gender marker and the procedure or diagnosis code. This modifier alerts the payer that the coding is intentional and not an error.
In the example provided—feminization rhinoplasty for a trans female patient—there is typically no conflict between the gender marker and the procedure or diagnosis code. As such, the KX modifier would generally not be necessary.
It’s important to note that modifier KX indicates that “requirements specified in the medical policy have been met.” This modifier is not exclusive to gender-affirming procedures and may be used in other contexts.
In closing, always consult the payer-specific policy and your internal coding compliance guidelines to ensure accurate and compliant use of modifiers.

Electrodessication with curettage (ED&C) Measurement
Good Afternoon, please clarify how lesions are measured for the destruction of malignant lesion codes 17260-17286. Is the code selection based on the size of the lesion before or after the curettage?
We are unable to find guidance from AMA or CMS. Our provider is stating that it is based on the size after curettage and basing it on this article at this link:
www.hmpgloballearningnetwork.com/site/thederm/site/cathlab/event/size-matters#:~:text=Size After Curettage, but Before,a 1.5 cm/d measurement.

Answer:
For destruction of malignant lesion codes 17260-17286, the code selection is based on the size of the lesion AFTER curettage, but BEFORE electrodesiccation.
Destruction of malignant lesions (CPT codes 17260 to 17286) is selected based on the lesion size after curettage, but before electrodesiccation. This timing is important because:
Initial clinical appearance may be misleading - The lesion might appear to be a certain size clinically, but curettage helps visualize the true extent of the malignant tissue.
Curettage reveals actual lesion boundaries - After curettage, the physician can better assess the actual diameter of the lesion that needs to be destroyed.
Before electrodesiccation - The measurement should be taken after curettage but before the electrodesiccation (destruction) process begins, as the destruction process itself would alter the lesion size.

Tendon Repairs
Can you provide additional clarification regarding correct selection
for your tendon repair? AMA states code selection should be where the tendon is repaired not the originating area of the tendon.
Question:
Can you provide additional clarification regarding correct selection for your tendon repair? AMA states code selection should be where the tendon is repaired not the originating area of the tendon.
Answer:
We appreciate you reaching out. AMA guidance is correct for repairing of tendons. CPT code selection for tendon repairs with grafts are based on the recipient site not the donor site.

Still Unlisted?
I hope KZA can provide clarification. In the past, when coding EDAS for treatment of MoyaMoya disease, I used unlisted code 64999 compared to 61711. I have recently seen articles using 61711 only. Which would be the most appropriate code to use?

Answer:
Thank you for asking KZA!
Encephaloduroarteriosynangiosis (EDAS) is an indirect revascularization technique designed to improve blood flow to the brain without directly connecting blood vessels. Because CPT 61711 specifically describes a direct extracranial-to-intracranial arterial anastomosis, this does not accurately reflect EDAS technique.
You have been reporting this correctly. There is no CPT code for this, which is appropriately reported with unlisted CPT 64999.
If you’re seeing 61711 used in articles, it may be due to confusion with direct bypass procedures, such as STA-MCA bypass, which do fall under 61711. For EDAS, however, 64999 remains the most accurate and compliant choice.
