New · DRG Grouping

The DRG, grouped from the codes your team approved.

When a chart is marked as coded, DeepMed groups it into its DRG from the selected codes and the encounter details on file. A rules-based grouper assigns the DRG - never a language model - and your DRG specialist reviews it before the chart is locked for billing.

DRGs from a language model
AI prepares the inputs; deterministic rules assign the DRG

Agentic AI where it helps. Rules where they must decide.

AI agents do the reading. A deterministic grouper does the grouping. Your team makes every decision that counts.

AI agents prepare the chart

Coding suggestions arrive with the passage behind them, and the encounter details the documents state are pre-filled with the exact excerpt, marked found by AI.

A rules engine groups it

The DRG comes from the scheme's own logic, applied rule by rule to the approved codes and facts. The same inputs always give the same DRG.

Your specialists decide

A DRG specialist accepts or rejects each result with a reason, and the DRG becomes final only when the chart is locked for billing.

Clinical documentation, from the first word to the final DRG

Six steps from the doctor's words to a coded, audited and grouped chart, with people reviewing the results along the way.

  1. DeepMed Dictate

    Dictate and approve: clinical dictation 

    Dictate or record the consultation with consent; the doctor approves the draft.

    Exports PDF, JSON or FHIR R4
  2. DeepMed Platform

    Read and protect: how a chart is read 

    Scans become text, and identifiers are masked before any AI sees them.

  3. DeepMed Platform AI-Assisted Coding

    Code: AI-assisted coding 

    Suggested codes arrive with the passage behind them, for the coder to accept.

  4. DeepMed Platform Coding Audit

    Audit: coding audit 

    A second AI pass scores the coding and proposes changes for the auditor.

  5. DeepMed Platform CDI

    Clarify: CDI and physician queries 

    Documentation gaps become neutral, non-leading physician queries.

  6. DeepMed PlatformThis page DRG Grouping

    Group: DRG grouping 

    A rules-based grouper assigns the DRG, final when the chart is locked.

From coded chart to final DRG

DRG grouping follows the coding, audit and CDI work your team already does. It never reopens them, and they never wait for it.

1
Coding

Only approved codes are grouped

The DRG is grouped from the chart's selected codes and nothing else. AI suggestions, audit proposals nobody accepted and physician responses not yet reconciled never reach the grouper.

Selected codes onlyPrincipal and secondaryOnset indicatorsDated procedures
2
Encounter information

The details a DRG needs, with where each came from

Admission and discharge dates, age, sex, separation mode and care type - and, where the scheme asks for them, admission weight, gestational age or ventilation hours. Agentic AI pre-fills what the documents state, with the excerpt, for the coder to confirm.

Every value records its source. Unknown and Not applicable are recorded as such - nothing is defaulted or guessed.

Needs information

Missing details are named, not guessed

When something is missing, the chart says what, why the scheme needs it, who can resolve it and where. Coding is never blocked - only grouping waits, and it starts by itself once the last item is resolved.

Unclear clinical documentation goes to CDI as a neutral query that never mentions the DRG, a weight or reimbursement.

Grouping

A rules engine assigns the DRG

The grouper receives structured codes and facts only - no names, no document text, no date of birth. Each answer is kept as a permanent record with its exact inputs, the rules it applied, and its edits and warnings.

Review

Your DRG specialist decides

Suggested DRG: the chart's DRG specialist - or its coder, while none is assigned - accepts the result or rejects it with a reason. Auto DRG: a clean result from a validated grouper is accepted for you, and a person's rejection is never overridden. No DRG: the chart is not grouped.

Always current

Change a code, and the DRG follows

Any accepted change to the grouping inputs - a code, an onset indicator, a procedure date, an encounter detail, the scheme or its version - marks the accepted DRG as outdated and groups the chart again. While the audit or CDI is still open, an accepted DRG is shown as provisional.

Lock for billing

Final when the chart is locked

Locking the chart makes the accepted DRG final, with its inputs, rules and answer preserved exactly as they were. A locked chart is never regrouped; reopening it takes a supervisor and a reason.

Every DRG shows how it got there

The DRG tab sits beside the codes. It shows where the chart stands, the result, the rules behind it and what is still needed - and compares any two calculations so you can see what changed between them.

  • Where it stands: waiting for coding, needs information, calculating, to review, accepted or final
  • The DRG with its MDC and severity, where the scheme supplies them
  • The rules the grouper applied, in order, each with its source
  • Code edits and warnings, with blocking errors kept apart
  • Every calculation and decision: what changed, and who decided
  • A DRG work list, dashboard tiles and filters for your DRG specialists

MS-DRG 44.0 To review
DRG 291 - Heart Failure and Shock with MCC · MDC 05, circulatory system
Why: principal diagnosis I50.23, acute on chronic systolic heart failure, assigns MDC 05; secondary J96.01, acute respiratory failure with hypoxia, is a major complication not excluded by the principal diagnosis.
Inputs: six diagnoses with onset indicators, two dated procedures, encounter information complete.
Decision: accept, or reject with a reason.

The DRG scheme of your jurisdiction

Each account chooses its diagnosis codes, procedure codes and DRG, each with its version, and every chart keeps its own. Codes are never translated from one classification to another.

Built in

MS-DRG v44.0

United States · ICD-10-CM / ICD-10-PCS

Built from the CMS grouper and its data, with the Medicare Code Editor v44 edits shown as warnings. It matched the official CMS grouper on 512,938 test claims, field for field.

Built in

CMG+ 2022

Canada · ICD-10-CA / CCI

Built from the CIHI CMG+ directory, including entry code, anaesthetic technique and intervention attributes, and checked on 78,402 cases drawn from it. Where the directory leaves a point open, the rule records the interpretation and why.

Your licensed grouper

AR-DRG

Australia · ICD-10-AM / ACHI

Connect your licensed AR-DRG grouper through the DeepMed grouper interface. Built-in AR-DRG V12.0 rules are in development and are not used to assign a DRG.

Built for compliant DRG work

Properties of how DRG grouping is put together, not promises in a policy.

No payment arithmetic

DeepMed assigns and records the DRG. It does not estimate, map or calculate reimbursement, and never shows a weight without its source.

Queries stay neutral

A documentation question raised for the DRG goes through CDI and never mentions the DRG, a weight or reimbursement.

The minimum to the grouper

Only structured codes and facts are sent - no names, no document text, no date of birth, no chart or patient identifiers.

Rules you can trace

Every built-in rule cites its source, and every calculation names the exact rules file that grouped it.

Validated before automated

Auto DRG accepts results only from a grouper an administrator has validated against reference cases.

A role of its own

DRG Specialist sits beside Coder, Auditor and CDI Specialist, with its own work list - and seeing a DRG grants no right to change codes.

Already licensed a grouper? Connect it.

DeepMed talks to every grouper through one small interface - an HTTP service or a command-line program. An administrator tests it, loads the details each version requires, and marks it validated once it agrees with the licensor's reference cases.

  • HTTP service or local command, with an optional key
  • A health check that lists the versions it groups
  • Each version's required details loaded from the grouper itself
  • A value the grouper cannot map is refused, never guessed
