IR-DRG in the UAE: what Dubai and Abu Dhabi require

Why the UAE chose IR-DRG

Two reasons, and both are practical rather than ideological. The first is coding: IR-DRG is built to produce a consistent classification across different coding conventions, and it works with the ICD-10-CM and CPT coding the Emirates already ran. Adopting a family that required ICD-10-AM and ACHI would have meant re-training every coder in the country first.

The second is scope. Most DRG families classify admitted care only. IR-DRG groups ambulatory encounters as well — day-case interventions, emergency attendances and other acute outpatient activity — which matters a great deal in a market where a large share of activity never becomes an admission.

Abu Dhabi: the longer-running mandate

Abu Dhabi moved first. The Department of Health made IR-DRG the accepted method for inpatient claiming from 1 January 2013, which makes the Emirate one of the longest-running DRG reimbursement environments in the region and means most providers there have a decade of casemix history to reason from.

That maturity changes what a provider should expect from a system. The question in Abu Dhabi is rarely "how do we start grouping" and usually "why does our casemix index look like this, and where are we losing to documentation".

Dubai: DRG on eClaimLink from September 2020

The Dubai Health Authority mandated DRG submission for all public and private hospitals in the Emirate from 1 September 2020, with claims exchanged through eClaimLink. The authority presented it as a move to link price directly to the service delivered, to reduce misuse and waste, and to stop paying for additional services with no clinical need.

For a provider the practical consequences are the familiar ones, arriving at once: coding becomes revenue-critical, documentation gaps become financial, and denials can now attack the grouping rather than only the line items.

What a provider needs in place

• Coders working in ICD-10-CM and CPT to the standard the payer audits against — the grouping is only as good as they are.
• Clinical documentation that records what was treated, not only what was done. An untreated-looking comorbidity is an unpaid one.
• A grouper whose version matches what the authority is measuring against, and a process for keeping it current as the classification is revised.
• Visibility of the episode before the claim is settled, so a documentation gap can be closed while it is still possible to close it.
• Reconciliation between what you grouped and what the payer grouped, because that difference is where recoverable revenue sits.

Grouping before coding is finished

The constraint most UAE providers actually hit is capacity: more episodes needing classification than there are coders to code them. Waiting for complete coding before the episode can be seen at all means the documentation gaps surface after the claim, which is the expensive order to discover them in.

NANO AIR-DRG exists for that position. It is NANO’s own automated International Refined grouper: it carries a procedural code set developed in-house alongside ICD and ACHI codes, treats ICD coding as an optional input rather than a precondition, and can output IR-DRG for claim submission. Scarce coding capacity then goes to the episodes where a human actually changes the answer.

If you also operate in Saudi Arabia

Then you are running two classifications, because Saudi Arabia groups on AR-DRG from ICD-10-AM and ACHI while the UAE groups on IR-DRG from ICD-10-CM and CPT. That is a requirement rather than a choice, and the cost of meeting it on two unrelated systems is two sets of rules to keep current, two audit surfaces, and no comparable view of casemix across the group.
