California PD Ratings

Done Right, Every Time

AI reads your QME report and extracts the facts. Then deterministic code — not AI — runs every step of the 2005 PDRS calculation. The same inputs always produce the same output.

Phase 1 — AI

AI reads the medical-legal report and extracts WPI, impairment codes, dates, occupation, and apportionment basis.

Phase 2 — Deterministic Code

Hardcoded PDRS tables and formulas run every calculation step. No AI involved. Same inputs = same output, always.

Every Step of the Math, Exposed

Here is exactly how a rating is computed — start to finish. Steps 2–6 are pure code. No AI touches the numbers.

Step 1 — AI ExtractionAI

AI reads the QME/AME report and pulls structured data.

Extracted Values

Impairment Code15.03.01.00 (Lumbar Spine)
WPI10%
Date of Birth1975-06-12
Date of Injury2023-03-01
Occupation Group490 (Light)
Apportionment Industrial80%

Step 2 — FEC Adjustment (×1.4)DETERMINISTIC

For SB 863 / 2005 PDRS cases, WPI is multiplied by 1.4 per LC §4660.1.

10 × 1.4 = 14

Inputs

WPI10%

Output

Adjusted WPI14%

Step 3 — Occupation AdjustmentTABLE LOOKUP

Looks up the adjusted value in the hardcoded PDRS occupation table for group 490.

Table lookup: 490C → 12

Inputs

Adjusted WPI14%
Occupation Group490

Output

Occupation-Adjusted12% (variant C)
4
Step 4 — Age AdjustmentTABLE LOOKUP

Worker is 47 at DOI. The PDRS age adjustment table maps 12% at age 47.

Table lookup: age 47 col → 13

Inputs

Occupation-Adjusted12%
Age at DOI47

Output

Age-Adjusted PD13%
5
Step 5 — ApportionmentDETERMINISTIC

Only the industrial portion of the disability is compensable.

round(13 × 0.80) = 10

Inputs

Age-Adjusted PD13%
Industrial %80%

Output

Industrial PD10%
6
Step 6 — Combined Values (CVC)DETERMINISTIC

Multiple impairments are combined using the standard CVC formula, not added.

10 + 8 × (1 − 10/100) = 17.2 → 17

Inputs

Impairment A10%
Impairment B8%

Output

Combined PD17%

Why the Math Is Never Left to AI

AI language models are powerful at understanding documents — but they can hallucinate numbers. The 2005 PDRS schedule is a set of fixed tables and formulas. We hardcode them. Every calculation is reproducible, traceable, and challenge-proof.

  • Same WPI + same occupation + same age = same PD rating, every single time
  • Occupation and Age adjustments are direct table lookups — not estimates
  • CVC formula is applied exactly per the schedule, not approximated
  • Full calculation trace is logged for every case — ready for any dispute

Data Privacy & Encryption

Your Data Is Encrypted at Every Layer

Reports are converted to vector embeddings that cannot be decoded back into text. On top of that, all case metadata is encrypted at rest on disk using AES-256-GCM — the same standard used by banks and government agencies.

Vector Embeddings
Documents are stored as high-dimensional numbers in a private vector database. There is no way to reverse embeddings back into readable text, names, or diagnoses.
AES-256-GCM at Rest
All case metadata — names, case numbers, extracted findings — is encrypted on disk with a key only you control. Even physical access to the server exposes nothing readable.
Never Used for Training
Your data is isolated to your case and never used to train AI models — yours or anyone else's.

Encrypted at rest. The case database on disk is AES-256-GCM encrypted. Each write uses a fresh random IV so no two writes look the same, and the auth tag ensures any tampering is detected and rejected.

Your key, your data. The encryption key is an env variable you set and own. We never see it, store it, or have the ability to decrypt your records.

Complete Security Package

Zero Internet. Zero Exposure. 100% On-Premise.

For firms that require the highest level of confidentiality, we offer a fully offline deployment. A custom AI model runs entirely on hardware inside your office — no data ever leaves your network. Not a single byte touches the internet.

  • Local AI model installed on your own hardware
  • No cloud, no external API calls, no internet required
  • All reports processed and stored entirely on-premise
  • Encryption keys stay on your hardware — only you hold them
  • We come to you, set everything up, and train your team
  • Ideal for firms handling sensitive HIPAA or attorney-client privileged records
