CAST Spine Surgery Categorization

Categorize spine surgery CPT codes into CAST fellowship form categories using rule-based logic validated by Claude AI.

Covers 116 procedure categories across 7 CAST sections: CVJ, Subaxial Cervical, Thoracic, Lumbosacral, Spinal Trauma, Deformity, and Spinal Oncology.

Developed by NIAA

How It Works

1
Single Row
Enter CPT codes for a single case. The system applies base categorization logic, then validates with Claude to determine the correct CAST spine surgery category.
2
Batch Analysis
Upload a CSV or Excel file with multiple rows of CPT codes. Each row is categorized independently, and results can be exported as CSV.
3
Spine Coding & Prior Auth
Paste an operative note, interventional procedure note, or planned order (surgery, injections, RFA, spine MRI/CT) and get CPT codes with rationale, ICD-10 codes, wRVUs, and payer prior-authorization requirements with an Epic-ready checklist.
4
Scenarios
Run test scenarios generated from AANS, NASS, and CPT coding references through the pipeline. Compare expected vs actual CPT codes and categories.
5
Review
Review pipeline results scenario by scenario. Approve or reject individual CPT codes, add comments, and apply approved changes to improve the reference data.

Quick Start

Categorize a case: Go to Single Row and enter CPT codes (e.g., 22551 22552 22845 20936). The system returns the CAST category with confidence score and reasoning.

Code from an op note: Go to Spine Coding & Prior Auth and paste a surgery description, interventional procedure note, or planned imaging order. Claude extracts CPT codes and ICD-10 codes, calculates wRVUs, and surfaces payer prior-auth requirements.

Test and improve: Go to Scenarios to run test cases from coding references, then Review results to approve corrections and improve categorization accuracy.
