Workflow

Overview

CaseMark's ICD-CPT Code Normalization skill automatically translates the dense diagnostic and procedure codes found throughout medical records into clear, attorney-readable language. It handles ICD-10-CM, legacy ICD-9, and CPT codes while flagging billing anomalies relevant to litigation. Whether you're building a medical chronology, drafting a demand letter, or reviewing itemized bills for a billing dispute, this skill eliminates hours of manual code lookups.

Medical records are filled with cryptic alphanumeric codes that are meaningless to attorneys without translation. Manually looking up each ICD-10, ICD-9, and CPT code across multiple reference databases is tedious and error-prone, and spotting billing anomalies like improper bundling or laterality mismatches requires specialized knowledge most legal teams don't have.

CaseMark's AI automatically identifies every diagnostic and procedure code in uploaded medical records, normalizes formatting inconsistencies, expands each code to its full narrative description, and cross-walks legacy ICD-9 codes to current ICD-10-CM standards. It also flags billing anomalies relevant to litigation, giving attorneys both the plain-language translations and the analytical insights they need without any manual lookup.

How it works

  1. 1. Upload medical records, billing statements, or HCFA-1500 forms containing diagnostic and procedure codes

  2. 2. AI identifies, normalizes, and expands every ICD-9, ICD-10-CM, and CPT code into attorney-readable descriptions

  3. 3. Billing anomalies such as bundling issues, laterality mismatches, and encounter coding errors are automatically flagged

  4. 4. Review the clean code translation table and export in your preferred format (DOCX, PDF)

What you get

  • Normalized Code Table with Plain-Language Descriptions

  • ICD-9 to ICD-10-CM Crosswalk Mapping

  • Billing Anomaly and Coding Flag Report

  • Methodology and Verification Notes

What it handles

  • Cross-walks ICD-9 codes to current ICD-10-CM equivalents automatically

  • Expands ICD-10-CM codes to full narrative descriptions with laterality and encounter context

  • Translates CPT procedure codes into plain-language procedure descriptions

  • Flags billing anomalies including bundling, unbundling, and incorrect encounter sequencing

  • Normalizes inconsistent code formatting (missing decimals, extra spaces) to standard form

  • Identifies laterality mismatches between documented findings and coded diagnoses

Required documents

  • Medical Records or Billing Documents

    Medical encounter notes, operative reports, itemized bills, HCFA-1500 forms, IME reports, or any documents containing ICD-9, ICD-10-CM, or CPT codes

    .pdf, .docx, .txt

Supporting documents

  • Case Summary or Context Notes

    Background on the case type (e.g., personal injury, billing dispute) to help prioritize which coding anomalies to flag

    .pdf, .docx, .txt

Why teams use it

Eliminate manual code lookups across ICD-10-CM, ICD-9, and CPT reference tables, saving hours per case

Catch billing anomalies like improper unbundling, laterality mismatches, and encounter coding errors that strengthen litigation arguments

Produce clean, consistent code translation tables that drop directly into demand letters, chronologies, and expert reports

Bridge legacy ICD-9 records and modern ICD-10-CM records with automatic cross-walking for cases spanning multiple years

Questions

What types of medical codes does this skill handle?

CaseMark's code normalization skill handles ICD-10-CM diagnosis codes, legacy ICD-9 codes found in older records, and CPT procedure codes. It automatically cross-walks ICD-9 codes to their current ICD-10-CM equivalents so you have a unified, modern code set.

Can it identify billing fraud or coding errors?

CaseMark flags common billing anomalies that are relevant to litigation, including improper bundling or unbundling of procedure codes, repeated initial-encounter codes across many visits, and laterality mismatches where the coded side doesn't match the documented injury. These flags help attorneys build billing dispute arguments.

Do I need to extract the codes from records first?

No. Simply upload the full medical records, encounter notes, operative reports, or itemized bills. CaseMark's AI automatically identifies and extracts every diagnostic and procedure code it finds, then normalizes and translates each one.

How does it handle older records with ICD-9 codes?

CaseMark automatically detects ICD-9 codes and cross-walks them to their current ICD-10-CM equivalents, providing both the original code and the modern translation so you can work with a consistent, up-to-date code set across records spanning different eras.

Is this useful for demand letters and medical chronologies?

Absolutely. CaseMark's code normalization is designed specifically for litigation workflows. The plain-language descriptions it generates can be dropped directly into demand letters, medical chronologies, and expert reports, eliminating the need for manual code lookups.

What if a code can't be verified?

CaseMark transparently marks any code it cannot verify with a clear notation and surfaces it in the methodology section of the output. This ensures attorneys always know which descriptions are confirmed and which may require additional verification.
