Code Navigator: clinical coding and DRG grouping, in your browser

Walk the classification, the way the standards say

Type a term and the Code Navigator opens the alphabetic index, with lead terms, modifiers and cross-references as they appear in print. Follow a reference into the tabular list, drill to the character the code needs, and read its inclusions, exclusions and notes before you take it. A code is only ever assigned from the tabular list, because that is where the exclusions live. A code you type straight into the worksheet goes through the same check.

• Diagnoses and procedures in the same worksheet
• Condition onset flags and, from the Thirteenth Edition, the diagnosis cluster on every row
• Hospital-acquired complications flagged against the national list, with the condition onset to confirm
• Every assignment timestamped and attributed

Check the grouping as you code

The grouper runs as codes are added, so an error DRG, an ungroupable episode or a missing data item shows while the record is still open, not after the episode is finalised. A sandbox runs the grouper with no patient attached: set the age, sex, length of stay, hours of ventilation and admission weight yourself, for training or for testing how the grouper treats an unusual case, without opening anybody's record.

• The DRG beside the worksheet, so grouping errors show early
• A sandbox for training and for testing the grouper on an invented case

The episode priced in NWAU, with the working shown

The Live DRG panel also prices the episode in National Weighted Activity Units, by IHACPA’s National Efficient Price Determination 2026–27. It starts from the price weight for the stay, then applies each adjustment the determination sets out, in its order: paediatric, Indigenous status, the patient’s and the hospital’s remoteness, radiotherapy and dialysis, ICU hours, and the private patient and accommodation adjustments. Every step is shown, so you can see how the figure was reached, and a fact the record does not hold, such as the patient’s remoteness area, can be set in the panel. NWAU is shown for the episode, never beside an individual code.

• NWAU(26), priced from the National Efficient Price Determination 2026–27
• Each adjustment shown in the order the determination applies it
• Missing facts, such as remoteness, set in the panel
• For the episode only, never per code
• For evaluation only during the tech preview: the 2026–27 prices are for AR-DRG V12.0 and the Code Navigator groups with V11.0, so this year’s figure is marked illustrative

What the codes you have taken still ask for

Beside the worksheet, the Code Navigator lists what the codes already taken still require. A "code first" instruction is shown as a warning, because it is not optional. A "use additional code" note is offered rather than demanded, because it applies only when it is clinically relevant. Where a code cites an Australian Coding Standard, the standard is a click away, along with the codes it directs you to assign, and the codes it tells you not to. National and state coding advice is applied in the same place, in the edition and jurisdiction that applies.

• Outstanding "code first" and "use additional code" instructions
• The coding standards each code cites, in the edition that applies
• Codes a standard directs you to assign, with the sentence that directs it
• Codes a standard tells you not to assign, flagged before you take them
• National and state coding advice, in the edition and jurisdiction that applies

De-identified in your browser, before anything is sent

When you upload a discharge summary or an operation report, your browser reads the PDF itself, using text recognition for scanned pages, and removes the patient's identifying details before you see a preview. Only the redacted text you approve is sent. The server checks it again and refuses it if an identifier has survived. Your coding is stored in Australia, in a tenancy that the database itself keeps apart from every other subscriber's.

• PDFs read and redacted in the browser, before anything is kept
• A second check on the server, which refuses text with an identifier in it
• Data stored in Australia
• Each subscriber isolated by row-level security in the database

Two ways to subscribe

Code Navigator, at $79 per coder a month, is the manual coder: the Code Navigator, the worklist and the live DRG, without Code Captain. Code Navigator + Code Captain, at $249, adds Code Captain with 200 runs per coder a month, shared across your team, and is in alpha preview. Both start with seven days free of the Code Navigator; Code Captain runs on AI, so while the preview is free each person can start a limited number of runs a day. HealthOS SaaS is in tech preview, free until 1 January 2027 unless we end it earlier, and we will tell you before anything is charged. Teams of about twenty coders or more can buy on invoice. See pricing.

• Code Navigator: the Navigator, worklist, live DRG
• Code Navigator + Code Captain: all of that, plus Code Captain (alpha)
• Prices in Australian dollars, excluding GST

The same coder, reading the whole record

Code Navigator is the coding screen on its own. HealthOS is the record that screen reads from. In a hospital running HealthOS, the coder works from the episode itself: the conditions the patient arrived with are frozen from the pre-admission record at admission, condition onset and hospital-acquired complications come from that comparison, and a finished code set goes on to the claim without being typed again. See clinical coding in HealthOS.
