Regulatory Guide · iDRG Casemix
JKN casemix is moving from INA-CBG to iDRG. We explain what changes and how to prepare your system — honestly: as of November 2026 there is no official national go-live, so we do not invent dates.
Background
iDRG (Indonesian Diagnosis-Related Groups) is being positioned as the successor to INA-CBG as the basis for JKN casemix tariffs. Trials of the new grouper have been running since around October 2025, but as of November 2026 there is no official national go-live date; the transition may proceed in phases or as dual-running. The Health Ministry and BPJS Kesehatan are also preparing a trial of iDRG together with capability-based referral (RBKP) and the standard inpatient class (KRIS) in Bandung city, Tulungagung regency, Makassar city, and Muara Enim regency — 94 hospitals and 464 primary-care facilities, for at most 12 months (ANTARA, 1 Oct 2026). According to the Ministry, that trial only takes effect once a Presidential Regulation is signed (Health Ministry, 2 Oct 2026); as of 8 November 2026 we have not found it issued. Final iDRG tariffs have not been set.
That is why this page does not sell schedule certainty. Its focus: what changes, and the preparation that is useful whatever the final date turns out to be.
What changes
The gist: tariffs depend increasingly on clinical accuracy and documentation completeness — no longer just on ward class.
INA-CBG uses three inpatient severity levels — "I" (Mild), "II" (Moderate), "III" (Severe) — plus code "0" for outpatient care. According to the Health Ministry, iDRG expands them to five categories; training materials call these Complexity Level 0 (No CC) through 4 (Catastrophic CC), plus merge code 9.
More detailed grouping — tariffs depend increasingly on the accuracy of diagnosis, procedure, and severity.
Requires complete, consistent recording of complications & comorbidities (CC) and major CC (MCC) in the medical record.
iDRG is designed to no longer separate tariffs by hospital class and ward class, but to base them on clinical factors & facility competency instead.
Adievia's role: an E-Klaim module with a grouper and a fault-tolerant outbox queue, built to adapt to a new grouper format once the rules are finalized. What we can guarantee now is the foundation — not a claim of "full iDRG readiness" before the provisions are issued.
FAQ
iDRG (Indonesian Diagnosis-Related Groups) is the successor to INA-CBG as the basis for JKN (national health insurance) casemix tariffs. As of November 2026, iDRG is still in a phased transition and no official national go-live date has been announced. The national trial of the new grouper has been running since 1 October 2025. A combined trial of iDRG with capability-based referral (RBKP) and KRIS in four areas — 94 hospitals and 464 primary-care facilities, for at most 12 months — only takes effect once a Presidential Regulation is signed, and as of 8 November 2026 we have not found it issued. Final iDRG tariffs have not been set. We do not invent dates.
The severity scheme changes: INA-CBG uses three inpatient severity levels (I/II/III, determined by whether CC/MCC are present in the secondary diagnosis) plus code "0" for outpatient care, while according to the Health Ministry iDRG expands them to five categories — training materials call these Complexity Level 0 (No CC) through 4 (Catastrophic CC) plus merge code 9. Other changes: grouping granularity is higher, documentation of complications and comorbidities (CC/MCC) becomes more detailed, and there is a move to remove tariff differentiation by hospital class and ward class toward clinical-based parity.
Because the exact date has not been set, the safest step is to fix what stays relevant in both schemes: clinical documentation quality (especially CC/MCC), ICD-10/ICD-9-CM coding discipline, and an internal claim-audit routine. This is an investment that is not wasted, whatever the timeline turns out to be.
Adievia's E-Klaim module is built with a grouper and a fault-tolerant outbox queue. This foundation — clean coding plus an architecture designed to adapt to a new grouper format — is what we can guarantee now, without promising "full iDRG" readiness before the rules are finalized.
