HCC Buddy — ICD-10 & Risk Adjustment

About

HCC Buddy is the all-in-one Chrome extension built for medical coders, Hierarchical Condition Category auditors, risk adjustment professionals, and clinical documentation improvement specialists. It puts the entire ICD-10-CM code set, HCC risk adjustment mappings, an AI-powered coding assistant, a drug-to-condition reference, National Provider Identifier lookups, and payer guideline search at your fingertips -- right inside a Chrome side panel so you never have to leave your Electronic Health Record system.

Why HCC Buddy?

Medical coders spend their days toggling between EHR platforms, CMS reference tables, coding manuals, and payer-specific guidelines. Every tab switch breaks your flow and costs time. HCC Buddy eliminates that friction by embedding a comprehensive coding toolkit directly in your browser. Open it as a side panel, and it stays alongside whatever chart you are reviewing -- no more alt-tabbing, no more lost context.

ENCODER -- Full ICD-10-CM Code Browser

The Encoder provides a complete, navigable ICD-10-CM code browser covering every fiscal year from 2016 through 2026. Browse by chapter, search by code or keyword, view full code details with HCC mappings, switch between fiscal years, and bookmark frequently used codes. Open the full-tab Encoder with a two-panel layout for deep research sessions.

ASK -- AI-Powered Coding Assistant

The Ask tab answers ICD-10-CM coding questions using retrieval-augmented generation across official ICD-10-CM coding guidelines, CMS publications, expert coding training videos, and RADV documents. Type a question in natural language and receive a detailed answer with source citations.

DRUGS -- Medication and Condition Cross-Reference

Search for a medication to see conditions it is prescribed for, or search by condition to see associated medications. Essential for validating that documented diagnoses are supported by the patient's active medication regimen.

NPI -- National Provider Identifier Lookup

Search the NPPES NPI registry directly from the extension. Enter a provider name, NPI number, or specialty with optional state filter.

GUIDELINES -- Payer Guideline Upload and Search

Upload payer-specific guideline PDFs. HCC Buddy indexes the content so you can search within your uploaded guidelines directly from the Ask tab.

RIGHT-CLICK CONTEXT MENU

Select any text on any webpage and right-click to look up a code or ask the AI assistant about the selected text. The side panel opens automatically.

PRIVACY AND SECURITY

HCC Buddy does not collect, store, or transmit any patient data or Protected Health Information. The extension communicates only with its own first-party API server at api.hccbuddy.com. No data is shared with third parties.P
