Coding PitfallsJessica K. Dohler, BS, CTR
Objectives
0Know how to code the Tumor/Ext Eval code when using intraoperative findings
0Know when to code “none” vs. “unknown” by using the Inaccessible LN Rules
0Understand the 2012 FORDS Grading guidelines changes
0Understand the limitations of imaging in prostate staging
TS/Ext Eval 1 or 3Is information on an operative report TS/Ext eval code 1 or 3?
TS/Ext Eval 1 or 3Eval Code Choices for OP Findings
Eval Code 1 - Clinical Eval Code 3 - Pathologic
0No surgical resection done.
0 Invasive techniques or surgical observation without biospy
0Surgical resection performed without neoadjuvant txt
0Based on evidence acquired before txt supplemented or modified by evidence acquired during & from surg
TS/Ext Eval 1 or 3Scenario – Exam and Op
Findings0CT of abdomen & colonoscopy negative
0Operative findings – sigmoidectomy & right oophorectomy• Bulky colon mass extends into
retroperitoneum• Peritoneal seeding• Thickened and suspicious right ovary
TS/Ext Eval 1 or 3Scenario – Pathology Report
0Sigmoid colon and upper rectum• Signet ring cell adenocarcinoma, high grade• Invades through muscularis propria into subserosal
fat• Proximal & distal margins negative• Radial margins, positive/involved
0Ovary – negative for tumor0Path staging • pT3 pN2a• 5/21 LN involved
TS/Ext Eval 1 or 3Summary: Op Findings vs. Path Report
0Op Findings• Tumor extends outside colon into retroperitoneum• CS Ext code 675, maps to T4b
0Path Report • Subserosal fat, radial margin positive• CS Ext code 400, maps to T3 (also stated by
pathologist)
Which takes precedence?
TS/Ext Eval 1 or 3Eval Code Choices for OP Findings
Eval Code 1 - Clinical Eval Code 3 - Pathologic
0No surgical resection done.
0 Invasive techniques or surgical observation without biospy
0Surgical resection performed without neoadjuvant txt
0Based on evidence acquired before txt supplemented or modified by evidence acquired during & from surg
TS/Ext Eval 1 or 3What Eval Code to Use?
0We know to code the extension to 675 since it is the most extensive
0Eval code 1 since info is from the op findings (observation during surgery)?
0Eval code 3 since there was a resection done?
TS/Ext Eval 1 or 3Scenario Answer
0Correct eval code is 3 – pathologic0Rationale• Supplemented/modified by evidence aquired during
and from surgery• Use information from op findings since nothing in path
overrides this information• Pathologist did not receive any tissue for the
retroperitoneumNOTE: op findings without surgical resection
would be eval 1.

Inaccessible Lymph Nodes
Coding “None” vs. “Unknown”
Inaccessible Lymph NodesWhat are they?
0Inaccessible lymph nodes are those that cannot be easily examined during a physical exam or observation.
0They are located within body cavities and cannot be palpated.
0Some primary sites with inaccessible lymph nodes• Bladder, colon, uterus, lung, liver, ovary,
kidney, prostate and stomach
Inaccessible Lymph NodesWhat’s the rule?
0Move to code “none” rather than “unknown.”0Three conditions must be met:• No mention of regional LN involvement on
PE, imaging or surgical exploration• Patient has clinically low stage (T1,T2 or
localized) disease.• Patient receives or is offered the usual
treatment for node negative primary site disease.
Inaccessible Lymph NodesScenarios
084 y/o male has 2.2cm LUL mass on CT, LN not mentioned.
0CT guided needle biopsy positive for adenoca.0Patient not a surgical candidate due to comorbidities.0Patient received steriotactic surgery to LUL mass only.
No chemo recommended.
Do you code CS LN to 000 or 999?• Correct answer = 000

058 y/o female with chest pain and shortness of breath.
0CT shows a 9.2cm mass in the RUL, no mention of LN.0CT guided biopsy of mass positive for SQCCA.0Patient receives radiation and refuses chemo.
Do you code CS LN to 000 or 999?• Correct answer = 999
Inaccessible Lymph NodesScenarios
062 y/o male with elevated PSA at 36.2.0DRE WNL0Prostate bx shows adenocarcinoma in 6/12 cores
with extracapsular extension. Gleason score 3+3=6.0Patient undergoes prostate seed brachytherapy

Grade Differentiation
2012 Changes
Grade Differentiation 2012 Changes
0Entire Morphology: Grade section of FORDS has been changed
0Jan 2012 Cases – CoC no longer supports site specific grade conversion
0SSF grading fields take precedence0Hierarchy of guidelines for coding morphology
grade differentiation
Grade Differentiation Guidelines
1. Hematopoietic and Lymphatic Grades
• Code in Grade/Differentiation field • All must be coded to 5-8 or 9• Code according to Hematopoietic and
Lymphoid Neoplasm Case Reportability and Coding Manual• Leave Grade Path System and Grade Path Value
fields blank
Grade Differentiation Guidelines
2. Special Grades
• Code in Collaborative Staging SSF fields• Code all SSF grade fields according to specific CS
instructions in CS Manual Part 1 Section 2• Gleason, Furhman, WHO, Nottingham or Bloom-
Richardson• Code Grade/Differentiation field as 9• Leave Grade Path System and Grade Path Value fields
blank
Grade Differentiation Guidelines
3. Grade Path System and Grade Path Value
• Other than hematopoietic and lymphatic or special grade• Documented in numeric form AND number of
grades in system known• DO NOT convert verbal description to numeric
codes• Code Grade/Differentiation field as 9
Grade Differentiation Guidelines
4. All Others
• Grade cannot be coded according to rules 1 through 3
• See table on page 12-13 of FORDS for complete list of verbiage/code conversion

Prostate ImagingCan I use imaging to determine if cancer is apparent or inapparent?
Prostate ImagingInapparent vs.
Apparent0DRE – gold standard for staging• Used to determine inapparent (not felt) or apparent
(felt)0 Imaging – TRUS, MRI, CT• Not used for staging unless managing physician
confirms• Not used due to limitations (too often results incorrect)• Interobserver variability• Lack of sensitivity and specificity
Prostate ImagingCS Extension Table Notes &
Clarification Note 3A:0A clinically apparent tumor is palpable or visible by
imaging.• Clarification: No list of words for imaging that determine
if visible. Only the clinician/managing physician can interpret.
0 If a clinician documents a "tumor", "mass", or "nodule“, this can be inferred as apparent.• Clarification: CS got permission to use these words for the
clinician, which only applies to the DRE. The words cannot be used for imaging.
Prostate ImagingCoding Scenarios
Patient has an elevated PSA and benign DRE per MD note. MRI report states the result as T2c. No managing MD stage. What is the CS Extension code?
0CS Extension Code = 150 • Since there is no managing MD stage the MRI report was
not supported by the managing physician. Therefore code 150 . Clinically inapparent tumor. Bx done for elevated PSA
Prostate ImagingCoding Scenarios
Unknown if DRE performed. No documented pre-bx PSA. MRI report states T2a prostate tumor. No managing physician stage. What is the CS Extension code?
0CS Extension Code = 300• Since there is no documented DRE or physician
statement it is unknown why the biopsy was performed. It is unknown if the tumor is apparent or not. Best to use the NOS code.
Prostate ImagingCoding Scenarios
Elevated PSA. Benign DRE. MRI shows nodule occupying greater than half of left lobe. Managing MD stage is T2. What is the CS Extension Code?
0CS Extension Code = 220• Although the managing MD T stage is T2nos it is safe to
code to cT2b since it is obvious that MD stage is based upon the MRI which specifically shows greater than half of one lobe involved with tumor.
