Scenario:  2023 abstracting case for St Elsewhere

Exam text: 75 YO Widowed White Female, Hispanic Presented with 2.5 cm lesion posterior right calf, no palpable inguinal lymphadenopathy, former smoker quit >10 years, no family history cancer, Height 64 inches Weight 125 lbs

Operative Text:

05/30/2023 Outside facility Dr Brooke: Right inguinal sentinel lymph node biopsy x5, Wide local excision of posterior right calf melanoma-The primary melanoma lesion was about 3 cm x 2 cm lesion excised with 1.5 cm margin

Surgery Text:

01/15/2023 Posterior right calf: punch bx @ St Elsewhere done by Dr Doe

05/30/2023 Wide local excision posterior right calf & sentinel lymph node biopsy (3 nodes removed) done by Dr Brooke at outside facility

Path Text:

01/15/2023 at St Elsewhere:  posterior right calf: punch bx: superficial spreading malignant melanoma, measuring 1.0 mm in depth, Breslow thickness: 1.0 mm, mitotic rate: less than 1 mitosis/mm2, no ulceration

05/30/2023 at outside facility SENTINEL LYMPH NODE #1, RIGHT INGUINAL, EXCISIONAL BIOPSY: One lymph node, negative for metastatic melanoma (0/1).

SENTINEL LYMPH NODE #2, RIGHT FEMORAL GROIN, EXCISIONAL BIOPSY:

negative for metastatic melanoma (0/3).

SENTINEL LYMPH NODE #3, RIGHT FEMORAL GROIN, EXCISIONAL BIOPSY:

negative for metastatic melanoma (0/1).

SKIN, RIGHT CALF, WIDE EXCISION: Melanoma, Histologic type: Superficial spreading

Breslow thickness: 1.7 mm, Ulceration: Not identified, Mitotic rate: 1/mm²

Margins negative (> 10 mm from all margins)

LVI: Negative

Question:  How would you code the surgical procedures?

Answer:

01/15/2023 B230-Punch Biopsy, NOS done at my facility St Elsewhere

05/30/2023 B530-Punch Biopsy followed by wide excision done at outside facility

Discussion:

Beginning in 2023 clinical melanoma margins will be coded from the operative report in the SSDI Clinical Margin Width. Margins are no longer part of the surgical code.

Another big change in 2023 is that shave, punch or elliptical biopsies are coded as surgical procedures no matter the margin status.  You would only code a surgical diagnostic & staging procedure if there was just a tiny amount of tissue is taken, which should be a rare occurrence.

Refer to the STORE Manual v2023 Posted 6/28/2023 Appendix M: The CTR Guide to Coding Melanoma Cases in STORE v23 for more information.
