03-10-2023 APPENDIX M: Case Studies for Coding Melanoma in STORE v23
Scenario:
- 01-01-2023 shave biopsy left thigh + melanoma in situ [done at my facility]
- 01-01-2023 Path: malignant melanoma, 0.5mm, margins negative
- 02-15-2023 wide excision left thigh 1cm margin around previous biopsy scar [done at outside facility]
- 2-15-2023 Path reports no residual melanoma in situ, margins clear
Question: How will these procedures be coded?
Answer:
| Field | Code | Rationale |
| Surgical Diagnostic and Staging Procedure | 00 | No core bx done [One significant change to the coding rules for cases diagnosed 2023 and after is that shave, punch, or elliptical biopsies are coded as surgical procedure regardless of margin status.] |
| Date of Surgical Diagnostic and Staging Procedure [ | Blank | |
| Date of First Surgical Procedure | 01/01/2023 | Date of shave biopsy |
| Date of Most Definitive Surgical Resection of Primary Site | 02-15-2023 | Date of the Wide Local Excision |
| RX Hosp Surg-2023 | B220 | Shave biopsy, NOS performed at reporting facility |
| RX Summ Surg-2023 | B520 | Shave Biopsy followed by wide excision performed at an outside facility |
| SSDI Clinical Margin Width | 1.0 | from WLE procedure note |
