Feature · AI Coding Assist

Deterministic coding, AI-assisted, audit-grade.

Every claim flows through 13 deterministic stages backed by the same national code catalogs your auditor uses — then a governed AI layer suggests reversible patches you can accept in one click.

The pipeline

Thirteen stages. One auditable trace.

Rules execute deterministically and in order. The AI layer never overrides a rule — it only proposes patches that can be safely auto-applied when they meet your tenant's confidence threshold.

  • • Reversible patches with field-level diffs
  • • Per-tenant confidence threshold (Conservative → Aggressive)
  • • Every decision written to the audit log with rule + rationale
  1. 1
    Catalog resolve
    Every code on the claim is normalized against the active national catalog (ICD-10-CM, CPT, HCPCS, Revenue, POS).
  2. 2
    Crosswalk validation
    CPT ↔ ICD plausibility checked against the platform-managed crosswalk.
  3. 3
    Modifier compatibility
    Modifier 25, 59, 50, RT/LT and payer-specific modifier rules applied.
  4. 4
    NCCI edits
    CMS National Correct Coding Initiative procedure-to-procedure edits, including Column 1/2 logic.
  5. 5
    MUE limits
    Medically Unlikely Edits — per-line maximum units enforced before submission.
  6. 6
    Bundling & global periods
    Global surgical packages, post-op windows, bundled labs and supplies flagged.
  7. 7
    Place-of-service validity
    POS / setting compatibility against the procedure (e.g., facility vs. office).
  8. 8
    Payer-specific rules
    Your contracted payer overrides — prior-auth required CPTs, frequency, age/sex edits.
  9. 9
    Facility edits
    For institutional claims: Type of Bill, MS-DRG, Revenue code validity, ancillary requirements.
  10. 10
    Duplicate detection
    Same patient + DOS + procedure detection across submitted claims, with override workflow.
  11. 11
    Documentation floor
    Heuristic check that note length and structure supports the billed E/M level before AI refinement.
  12. 12
    Fee schedule / pricing
    Lines compared against contracted allowables; under-pricing and over-pricing both flagged.
  13. 13
    AI refinement
    Governed AI reviews remaining risk, suggests reversible patches, and writes the rationale to the audit log.
Catalogs included

The national code sets you need, kept current, on every plan.

MedIQ centrally licenses and maintains the catalogs that drive correct coding — you never re-pay for them, never re-import them, and never run on stale data.

ICD-10-CM

Full diagnosis catalog with annual updates, includability flags, and short/long descriptions.

CPT

Procedure codes with descriptors, RVUs, and modifier guidance — refreshed on the AMA cycle.

HCPCS Level II

Supplies, DME, drugs, and non-physician services with category and coverage flags.

Revenue & Type-of-Bill

UB-04 revenue codes, TOB validity, ancillary requirements for institutional claims.

NCCI + MUE

CMS-published procedure-to-procedure edits and Medically Unlikely Edits, updated quarterly.

Modifier library

Payer-specific modifier rules — when 25, 59, 50, X{EPSU} apply (or don't).

Place of Service

POS codes with compatibility rules against the billed CPT.

Fee schedules

Bring your contracted allowables; the pricing stage compares line totals against them.

License attestation

Tenant admins attest to required code-set licenses (e.g., AMA) — tracked in the admin console.

E/M leveling

MDM floor first. AI refinement on top.

MedIQ derives the medical decision-making floor for an E/M visit from documented problems, data, and risk — deterministically. Governed AI only refines from that floor upward, never below it, and every change is logged with the rationale.

  • Documentation-supported
    If the note doesn't carry the level, we don't bill it.
  • Conservative-by-default
    Auto-apply patches only run when above your tenant's confidence threshold.
  • Reversible
    Every patch can be undone with a single click; the original is preserved.
