14000 and 19301 for Partial Mastectomy?

Should cpt code 14000 ADJACENT TISSUE TRANSFER OR REARRANGEMENT, TRUNK; DEFECT 10 SQ CM be billed with cpt code 19301 MASTECTOMY; PARTIAL. Insurances tend to disallow it stating it is included in 19301. This is how our surgeon describes 14000 a parenchymal flap advancement was used to close there is minimal breast parenchyma left at the inferior margin. Advancing this into the lumpectomy cavity does create some distortion along the inframammary fold. Therefore, the breast tissue both above and below the lumpectomy cavity is released from the underlying chest wall. They form a well vascularized broad based pedicle. This is advanced into the lumpectomy cavity and secured together with interrupted 3-0 Vicryl sutures. Approximately 10 sq cm of tissue are mobilized in this fashion. Thank you for your help.

Answer:

No, 14000 ADJACENT TISSUE TRANSFER OR REARRANGEMENT, TRUNK; DEFECT 10 SQ CM is not reported with a partial mastectomy (lumpectomy) code 19301 for a local advancement flap, which is what is described in your question

Elimination of dead space is inherent to a mastectomy procedure. Local advancement flaps and oncoplastic repair are included in a mastectomy procedure.

Pyogenic Granuloma

Hello! Could KZA clarify if the excision of a pyogenic granuloma (lobular capillary hemangioma) would be assigned to a code from the musculoskeletal or integumentary system? We have seen some conflicting information.  

Question:

Hello! Could KZA clarify if the excision of a pyogenic granuloma (lobular capillary hemangioma) would be assigned to a code from the musculoskeletal or integumentary system? We have seen some conflicting information.  

Answer:

Thank you for reaching out to KZA!

The origin of the lesion will direct you to the appropriate code selection.

According to CPT:

  • Lesions of cutaneous origin are appropriately reported with the excision of lesion integumentary codes (114xx & 116xx).

  • Lesions of non-cutaneous origin are appropriately reported with the excision of tumor codes from the musculoskeletal section of CPT (2xxxx).

Pyogenic granulomas are benign, generally considered of cutaneous origin, and reported with a 114xx benign lesion code. If the documentation is unclear, it is best practice to query the surgeon for clarification.

Secondary Closure?

I’m a new coder, and my physician closed a fasciotomy wound. I’m unsure what to do with this, so I seek some much-needed guidance. I’m looking at 13160. The surgeon debrided tissue and closed the wound.

Answer:

Thank you for reaching out—great job identifying CPT 13160. You're on the right track. If this is a secondary closure of a fasciotomy wound, CPT 13160 (Secondary closure of surgical wound or dehiscence) is appropriate.

Reporting Modifiers with Unlisted Codes

Can modifiers be reported with unlisted CPT codes?

Question:

Can modifiers be reported with unlisted CPT codes?

Answer:

Yes, modifiers can be appended to unlisted CPT codes.

In 2024, CPT clarified this by updating the introduction guidelines for unlisted procedures and services. These updates were further explained in the January 2024 issue of CPT Assistant, which addressed the new and revised text and the standardization of reporting unlisted CPT codes across the CPT code set.

 

Illustration of modifiers that may be appropriately applied includes:

  • Laterality modifiers – e.g., RT (right), LT (left)

  • Bilateral procedure modifier – 50

  • Role-based modifiers – e.g., 62 (two surgeons), 80 (assistant surgeon), 82 (assistant surgeon when qualified resident not available), AS (non-physician surgical assistant)

  • Multiple or distinct procedure modifiers – e.g., 51 (multiple procedures), 59 (distinct procedural service)

  • Global modifiers – e.g., 58 (staged or related procedure), 78 (return to operating room for related procedure), 79 (unrelated procedure or service)

This is not an all-inclusive list of modifiers that may be appropriately applied to unlisted CPT codes. For complete and up-to-date information, one should refer to current CPT guidelines and payer-specific policies.

 

Please note: Modifiers that describe an alteration of a service or procedure, such as modifier 52 (reduced services), are not appropriate for use with unlisted codes. The same applied to modifier 22 (increased procedural services).

Excisional Debridement (1104x) vs. Surgical Preparation (1500x)

Our surgeon is taking a patient to the OR to excise a surgical wound dehiscence, which will be closed with a skin graft. We are looking at debridement codes 1104x and the skin graft codes (15xxx). Are we on track?

Question:

Our surgeon is taking a patient to the OR to excise a surgical wound dehiscence, which will be closed with a skin graft. We are looking at debridement codes 1104x and the skin graft codes (15xxx). Are we on track?

Answer:

Thank you for reaching out to KZA!

You're on the right track with the skin graft codes (15xxx series). However, for the debridement portion, it's important to note that the 1104x codes are typically used when the wound is being debrided with the expectation of healing by secondary intention—that is, without primary closure or grafting.

In your scenario, since the wound will be closed with a skin graft, the more appropriate coding would come from the surgical preparation code set (15002–15005). These codes are specifically intended for excisional preparation of a wound bed before grafting or other definitive closure.

Complex Close with FTSG

We want to confirm with KZA if a complex closure with extensive undermining is required to close the donor site where an FTSG was taken. Can we separately report the closure?

Question:

We want to confirm with KZA if a complex closure with extensive undermining is required to close the donor site where an FTSG was taken. Can we separately report the closure?

Answer:

No, this is not separately reportable. The CPT descriptors for the full-thickness skin grafts (FTSG) code set specifically state “including direct closure of the donor site”.

*This response is based on the best information available as of 8/28/25.
