Definition and classification of the DRG system
The DRG system is a performance-based payment system for inpatient hospital care. Treatment cases are grouped into case groups, for which flat-rate fees are generally paid.
The aim of the DRG system is to enable standardised, comparable billing of inpatient services based on medical and billing-related characteristics.
linqi supports hospital staff in the procedural and document-related use of the DRG system: information is recorded digitally and in a structured manner, documents are created to a standardised format, and evidence for billing and audit processes is provided consistently.
Definition: What does DRG stand for?
The abbreviation DRG stands for Diagnosis-Related Groups. This means that the classification system groups cases with similar clinical characteristics and comparable resource consumption into defined groups.
Basics of the DRG system in hospitals
The DRG system replaces billing based on length of stay with a flat-rate per-case payment model.
The amount of the fee is essentially determined by:
- assignment to a DRG (via coding and grouping)
- a valuation ratio (relative weight)
- the state-level base case value
Depending on the specific circumstances, surcharges, discounts, additional fees and other budgetary elements may also apply. In Germany, costs for nursing staff at the patient’s bedside have been reimbursed separately for several years.
Process: How does DRG billing work?
The billing process can be broken down into five steps:
Step #1: Provision of services and documentation
Relevant information is documented throughout the entire stay (admission, diagnosis, treatment, procedures, progress, discharge). This structured, traceable documentation is also particularly important in the context of the electronic patient record (ePA), as relevant treatment information must be provided consistently, thereby supporting billing, record-keeping and cross-sector collaboration.
Point #2: Coding (medical classifications)
Diagnoses and procedures are coded using standardised systems (e.g. ICD and OPS). In addition, case-specific data is taken into account, such as age, reason for discharge, length of stay or ventilation times.
Point #3: Grouping (DRG assignment)
Grouping software assigns the case to a DRG based on the coded information.
Point #4: Remuneration calculation
The fee is determined on the basis of the valuation ratio in conjunction with the regional base case value. Additional regulations influence the remuneration in detail (e.g. in the case of extremely long lengths of stay).
Point #5: Billing, documentation and verification
The case is billed. Subsequently, documentation and audit processes may become relevant, in which the completeness and plausibility of the documentation play a central role.
Practical application: How linqi supports DRG billing
The main benefit of linqi lies in the automation and digitalisation of the DRG process, particularly where billing reliability in practice depends on the quality of documentation and the availability of records.
- Standardisation: Templates and structured processes reduce variations and increase consistency.
- Completeness: Checklists or defined process steps reduce the risk of missing information relevant to billing.
- Traceability: Documents are provided in a coherent manner, rather than being scattered across multiple filing systems.
- Efficiency in handover: Medical controlling, wards and functional areas all access the same set of information, which reduces queries and back-and-forth communication.
Using linqi to optimise DRG processes
Historical context: Introduction of the DRG system
The DRG system was introduced in Germany from 2003. 2003 served as an opt-in year; from 2004 onwards, DRG billing became mandatory for somatic hospitals.
Special topic: Case consolidation
Definition
In the DRG system, case consolidation refers to the rule-based grouping of several hospital stays into a single billing case, provided the stays are linked by a defined temporal and factual relationship.
Relevance
Case consolidation is particularly relevant in the case of readmissions. It serves to ensure that billing is accurately reflected and to avoid demarcation issues between separate stays.
Support for case consolidation in the DRG system provided by linqi
The practical challenge often lies in the timely identification of related admissions and in maintaining complete, consistent documentation.
This is where linqi can provide targeted support through:
- linking processes between related procedures,
- structured consolidation of documents into consistent packages,
- standardised justification and supporting documentation, which is made available more quickly for controlling and audit processes.

Discussion: Criticism of the DRG system
In professional and health policy discussions, the DRG system is also viewed critically.
The focus is on the following points, amongst others:
- Administrative burden: Coding, documentation and reporting tie up resources.
- Burden on clinical practice: Time pressure and organisational inefficiencies can increase if processes are not properly coordinated.
- Potential for audits and disputes: Missing or inconsistent documentation increases the risk of queries, corrections or loss of revenue.
How linqi can mitigate potential negative effects
linqi tackles the typical ‘follow-on costs’ encountered in day-to-day practice. The added value of the no-code platform is evident in various areas.
- Reduction of avoidable documentation loops
- Strengthening audit readiness through consistent documentation
- Time saved through fewer searches, fewer queries and smoother handover processes
Development of the DRG system in hospitals
The DRG system remains a central component of hospital remuneration, but has been supplemented by additional elements for years. In practice, this increases the importance of process quality and evidence-based logic, as more interfaces, sets of rules and billing components interact with one another. Hospitals are therefore increasingly benefiting from standardised, transparent documentation and process structures.
FAQ: DRG system
What is DRG, explained simply? +-
DRG is a hospital payment system in which inpatient treatment cases are grouped into case groups and are generally reimbursed on the basis of flat-rate payments rather than on a per-day basis.
How is a DRG flat-rate payment calculated? +-
The fee is generally calculated as the assessment ratio (relative weight) multiplied by the national base case value, plus any surcharges, discounts and additional fees where applicable.
How does DRG billing work? +-
Diagnoses and procedures are documented and coded, assigned to a DRG using a grouper, and then billed according to the assessment ratio and the regional base case value, including any applicable supplementary rules.
Is the DRG system being abolished? +-
At present, the plan is to scale back the purely flat-rate per-case payment system (with additional capacity-based remuneration, approximately 60 per cent of which is service-independent and approximately 40 per cent continuing to be based on treatment cases), rather than to abolish it entirely.
How does linqi support DRG processes on a day-to-day basis? +-
Through standardised process steps and consistent document packages, linqi can improve the completeness of documentation and significantly reduce the workload involved in billing, verification and audit processes.
