Pathology Coder

SNOMED CT and ICD-O-3 coding suggestions for pathology reports with clinical context.

When to Use This Skill

Use this skill for:

• LIS integration and coding
• Tumor registry reporting
• Billing support
• Standardizing terminology
• Teaching pathology coding

Supported Code Systems

• SNOMED CT: Morphology, topography, procedures, qualifiers
• ICD-O-3: Morphology codes with behavior, topography codes

Key Features

1. Diagnosis Coding: Tumor type, grade, behavior codes
2. Procedure Coding: Specimen types, special stains, IHC
3. Biomarker Coding: ER/PR/HER2/MSI/MMR codes
4. Hierarchical Relationships: Parent concepts, synonyms
5. Multi-code Support: Combined diagnoses and qualifiers

Reference Files

Reference on-demand (DO NOT load at startup):

• Code tables: ../../shared-references/coding/snomed_ct_codes.md

Usage Examples

# Code diagnosis
claude "SNOMED code for invasive ductal carcinoma grade 2 using pathology-coder"

# Code procedure
claude "What is the code for HER2 immunohistochemistry using pathology-coder"

# Multiple codes
claude "Code breast lumpectomy with IDC and DCIS using pathology-coder"

Processing Instructions

1. Parse diagnosis/procedure from user input
2. Load code table from shared-references
3. Look up SNOMED CT code and ICD-O-3 if applicable
4. Provide hierarchical context: Parent concepts, synonyms
5. Output: Code(s) with descriptions and relationships

Common Tumor Type Codes

Loaded on-demand from reference file when needed:

• Breast carcinoma codes
• Colorectal carcinoma codes
• Pancreas carcinoma codes
• Gastric carcinoma codes

Output Format

For each code suggestion:

• SNOMED CT: [Code] | [Preferred term] | [Hierarchy]
• ICD-O-3: [Morphology/Behavior] | [Topography] | [Description]

Note: Minimal skill definition. Code tables loaded on-demand during processing only.
