20081014 Surgery of Primary Site--Prostate: How is transurethral microwave treatment coded for prostate primaries?

Assign code 16 [Hyperthermia]. See the SEER Note on page C-747 of the 2007 SEER Manual:

Code Transurethral Microwave Thermotherapy (TUMT) as 16.

 2008
20100038 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. 2010
20010025 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.

20041050 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. 2004
20010007 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. 2001
20031105 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."

20021026 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]. 2002
20031203 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. 2003
20051026 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. 2005
20031004 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.
