Server Instructions

An MCP server for accessing ICD-10-CM (diagnosis) and ICD-10-PCS (procedure) codes. This server provides: - Tools: Search codes by code number or description, validate codes, explore hierarchies - Code types: ICD-10-CM for diagnoses, ICD-10-PCS for inpatient procedures - Features: Full descriptions, billing validation, category exploration, body system navigation ICD-10-CM codes are used for diagnosis coding in the United States healthcare system. ICD-10-PCS codes are used for inpatient procedure coding. This server uses the 2026 code sets. TOOL SELECTION GUIDE: • lookup_code: Get details for a specific code when you know the exact code (e.g., 'E11.65', 'C92.11') • search_codes: The unified search tool. Use it for: - Finding diagnosis codes by prefix (e.g., query='E11', code_type='diagnosis', search_by='code') - Finding diagnosis codes by description (e.g., query='diabetes', code_type='diagnosis') - Finding procedure codes by prefix (e.g., query='0DT', code_type='procedure', search_by='code') - Finding procedure codes by description (e.g., query='appendix', code_type='procedure') • validate_code: Check if a code is valid and billable for HIPAA transactions • get_chapter/get_category: Navigate code hierarchy to understand related codes MULTI-TOOL WORKFLOWS: For comprehensive diagnosis analysis: 1. Use search_codes (by description) to find relevant codes by disease name 2. Use lookup_code to get full details including billability status 3. Use get_category to understand related codes in the same family 4. For disease progression scenarios, look up related status codes DISEASE PROGRESSION PATTERNS: Many conditions have related codes for different stages - always look up the full set: • Cancer: primary site codes, 'in remission' codes, 'relapse' codes (e.g., C92.10 → C92.11 → C92.12) • Diabetes: codes with/without complications, type specification • Heart disease: acute vs chronic phase codes • Use search_codes (by code) with the base code prefix to find all related codes
