Surgery of Primary Site--Prostate: Is a prostate saturation biopsy coded under diagnostic biopsy or surgery?
A prostate saturation biopsy is a transperineal template-guided stereotactic saturation prostate biopsy that typically produces 30 to 80 core biopsies. This is an alternative biopsy technique used for some high-risk patients including men with persistently elevated PSA, those who have atypia on prior prostate biopsies, or men with biopsies showing high-grade prostate intraepithelial neoplasia (PIN). Although this is a different procedure, it is still a diagnostic biopsy. Do not code prostate saturation biopsy under Surgery of Primary Site.
Surgery of Primary Site--Prostate: What treatment code is used to represent prostate carcinoma treated with "high intensity focused ultrasound" (HIFU)?
For cases diagnosed 1998 and later:
Code the Surgery of Primary Site field to 17 [Other method of local tumor destruction]. HIFU uses focused energy to destroy tissue. It is classified as a surgical procedure.
Surgery of Primary Site--Rectum: How do you code a procedure described as a "transanal resection, debulking of a large rectal mass"? See Discussion.
Patient is not a surgical candidate due to "other medical conditions". Colonoscopy done for anemia and rectal bleeding. At the colonoscopy a "Transanal Resection Debulking of large rectal mass" is performed. Two specimens are sent to the lab. The first is labeled "rectal mass" and is a 2.0 cm diameter spherical fragment of tissue. The second is labeled "transanal debulking rectal mass" and is described as multiple, irregular shaped fragments of tan, rubbery tissue measuring 5.0 x 5.0 x 3.0 cm. Final path diagnosis: Debulking of rectal mass: Adenocarcinoma greater than 2 cm in size, resection margins positive for tumor.
For cases diagnosed 1998-2002, code Surgery of Primary Site to 20 [Local tumor excision, NOS]. Because the procedure was performed via colonoscopy and apparently did not involve proctectomy, the best choice is a local excision.
Surgery of Primary Site--Skin: For skin primaries diagnosed 1998-2002, what is the difference between code 40 [Wide excision or re-excision of lesion or minor (local) amputation, NOS] and 50 [Radical excision of a lesion, NOS]?
Codes 40 and 50 are not in the scheme for 2003 forward. See history for coding cases diagnosed 1998-2002.
Surgery of Primary Site--Skin: How should this field be coded for a re-excision or wide excision of a skin primary when the margins are NOS?
For cases diagnosed 2003 and later:
Assign surgery codes 45, 46 and 47 only when the margins are documented to be more than 1cm. Use the most appropriate code from 30-36 if re-excision or wide excision followed a biopsy. Use a code from the 20's series if the procedure is called a "biopsy."
Surgery of Primary Site--Skin: Should Mohs surgery be code to 27 [Excisional biopsy] or 31 [Shave biopsy followed by a gross excision of the lesion]? See discussion.
Under surgery coding in the 5/22/01 SEER Abstractor/Coder Workshop book, page 20, it states that Mohs surgery should be coded as an excisional biopsy. The ACoS I&R dated 6/6/2001 states that it should be coded to 31.
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 34 [Mohs surgery, NOS], 35 [Mohs with 1-cm margin or less] or 36 [Mohs with more than 1-cm margin].
Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm?
Use code 46 [Wide excision...with margins more than 1 cm and less than 2 cm] when margins are exactly 2 cm.
Surgery of Primary Site--Skin: What surgery code is used to reflect the amputation of a finger for subungual melanoma?
47 [Wide excision or reexcision of lesion or minor (local) amputation with margins greater than 2cm] is the correct surgery code for amputation of a finger for melanoma.
Surgery of Primary Site--Skin: When would one use codes 30-33 for this field on a skin primary?
Surgery of Primary Site codes 30-33 under "skin" are used for various types of biopsies followed by a gross excision of the lesion. The two procedures (biopsy and gross excision) may be performed on different days, at different facilities, by different physicians as long as both procedures are performed during the first course of treatment.
Answer applies to both pre-2002 and 2003+ surgury code definitions.
Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed.
