ICD-10 Auto-Coding. Code suggestions from your documentation — the decision stays with the physician.

The coding assistant is a dedicated module of the Aescuris software. It reads the documented consultation text and proposes matching ICD-10-GM codes — including a reference to the source text and alternative options. Locally on your hardware. No cloud. No data leaves your network. Clinically guided, supportive in scope — the final coding decision is made by the physician.

STATUS QUO

14,000 codes, one consulting room, limited time.

The ICD-10-GM catalogue contains around 14,000 codes. Selecting the right ones is demanding because the choice sits between treatment, documentation and billing — and because it may later be reviewed by the regional physicians\' association and by the Medical Service. The coding assistant supports preparation precisely at this point.

~ 14,000

Codes in ICD-10-GM

The complete catalogue is available via the regional physicians\' association and online catalogue browsers. Looking up codes during a consultation is practically not feasible.

Several

Secondary diagnoses per case

For multimorbid patients, secondary diagnoses are relevant for the diagnostic thesaurus and for billing — yet they are frequently missed in the rush of a busy consultation.

Confirmed / suspected / status post / excluded

Diagnostic certainty

The classification as a confirmed, suspected, status-post or excluded diagnosis is mandatory and relevant for audits — a frequent source of corrections by the regional physicians\' association or the Medical Service.

HOW IT WORKS

From documentation to reviewed coding in four steps.

The coding assistant is a dedicated interface within the Aescuris software. Data is handed over from your practice management software via established interfaces. Suggestions are shown inside the Aescuris dialogue — the decision is made by you as the physician.

  1. 01

    Provide the consultation text

    You dictate or document as usual — medical history, findings, course of treatment — in your practice management software. Aescuris takes the text in via the GDT interface, via import/export or through a simple copy step into the module. On request, the transfer happens automatically in the background as soon as you open the relevant patient record.

  2. 02

    Review code suggestions

    The coding assistant analyses the text against the current ICD-10-GM catalogue and proposes matching diagnosis codes — including a reference to the source text, alternative codes and a note on frequently overlooked secondary diagnoses. Each suggestion is presented transparently so you can trace where it comes from.

  3. 03

    Select, adjust, dismiss

    You decide for each suggestion whether to accept, edit or dismiss it. Additional codes can be added manually. The ordering of primary and secondary diagnoses, as well as the diagnostic certainty marker (confirmed / suspected / status post / excluded), stays in your hands.

  4. 04

    Transfer into the practice management software

    The approved code list is transferred via a simple copy function or via the established interfaces into your practice management software. On request, more advanced integrations can be set up — for example a direct hand-over into the billing record. The final clinical assessment and responsibility for the coding remain with the treating physician in every case.

USE CASES

Three typical coding settings.

Where the coding assistant contributes most depends on the practice structure and the patient cohort. Three examples:

GP PRACTICE

Multimorbidity and status-post codes

High patient volume, many chronically ill patients, pronounced multimorbidity. Secondary diagnoses and encounters such as preventive care, follow-up or status-post conditions are easily missed in the rush of a busy consulting day.

Effect with Aescuris: the assistant offers complementary code suggestions based on the documented course of treatment. The physician decides which to accept — the coding becomes more complete without additional research time.

SPECIALIST PRACTICE

Specific codes within the speciality

Diagnoses sit deep in the catalogue, with fine-grained differentiation (location, acute / chronic, complications). Manual look-ups are time-consuming — the result is often a generic code, even though a more specific one would be available.

Effect with Aescuris: the assistant suggests specific codes commonly used in the speciality and makes the differentiation visible. The physician reviews and accepts — coding depth increases without changing the workflow.

MVZ · CLINIC AMBULATORY

Consistency between physicians

Several physicians work with overlapping patient cohorts. Different individual coding habits lead to heterogeneity in statistics and billing — and to elevated audit risk.

Effect with Aescuris: the suggestions are based on the same catalogue and the same review rules. Coding becomes more consistent between physicians without restricting the clinical decision.

CLINICAL GUIDANCE

Designed with a general practitioner who knows audits from the field.

Coding is a double-edged topic. If it is too vague, the practice loses money. If it is too generous, the Medical Service will reclaim it. AI must not claim anything here that is not actually in the consultation text. It should make suggestions — and the physician decides. That boundary is the guiding principle for the Aescuris coding assistant.

SECURITY & GDPR

Coding without data leaving the practice.

The consultation text to be coded contains patient data of the special category under GDPR Art. 9. Aescuris is therefore consistently designed as an on-premise solution.

On-premise architecture

Language model, ICD-10-GM catalogue and consultation texts remain on the practice server inside your network. No cloud routing, no external inference endpoints.

No external processing

Because Aescuris does not process the data on your behalf — your practice carries out the processing on its own hardware — there is no need for a separate data processing agreement, a frequent hurdle with cloud-based solutions.

Medical confidentiality (§ 203)

The architecture is designed to align with German medical confidentiality obligations. There is no path through which the consultation text could reach Aescuris or any third party.

Auditability

Every suggested and accepted coding is logged with timestamp, source-data reference and model version — for internal documentation and for any external audits.

FREQUENT QUESTIONS

Answers to what practices ask us most.

Which ICD version does the Aescuris coding assistant use?
Aescuris works with ICD-10-GM (German Modification), which is the version mandated for use in Germany, in the version currently published by the German Federal Institute for Drugs and Medical Devices (BfArM). When the catalogue is updated, the version on the Aescuris server is rolled out centrally — the practice does not need to maintain anything manually.
How reliable are the ICD-10 suggestions?
The suggestions are produced by a language model tuned for German-language medical terminology, working against the ICD-10-GM catalogue. Each suggestion remains exactly that: a suggestion. The clinical assessment, the selection of the applicable codes and the legal responsibility for the coding remain with the treating physician. Aescuris does not replace a physician's coding decision and does not replace any billing or audit review.
Are secondary diagnoses and status-post codes also suggested?
Yes. The coding assistant identifies references to concomitant and follow-up diagnoses as well as encounters such as preventive care, status-post conditions or exclusion findings and presents them as suggestions. The classification as primary or secondary diagnosis and the diagnostic certainty are decided by the physician.
Does patient data stay inside the practice during coding?
Yes. Aescuris runs entirely locally on a dedicated practice server. The consultation text to be coded does not leave your network at any point — no cloud upload, no external API calls, no telemetry. The module is therefore designed to support the requirements of GDPR Art. 9 and German medical confidentiality (§ 203 German Criminal Code).
Can the coding assistant be connected to our existing practice management software?
Aescuris is designed to integrate with the common German practice management systems. Connections are made via established interfaces such as KBV interfaces, GDT or a dedicated practice-to-Aescuris bridge. During the pilot programme we assess the specific setup at no cost and put the integration in place.
Does the coding assistant replace a billing review or a medical service audit?
No. The coding assistant supports the physician's coding decision during documentation. It is not a billing review, not a plausibility module of the regional physicians' association, and not a substitute for review by the Medical Service (Medizinischer Dienst). Responsibility for the correctness of the coding vis-à-vis the regional physicians' association, the health insurance fund and the Medical Service remains with the practice.
How much does the ICD-10 auto-coding module cost?
The module is part of the Diagnostics pillar and can be activated individually. During the 2026 pilot programme, use is free of charge in the pilot phase. After that, billing is per practice and per month — the scope is agreed transparently before activation.
Who provides the clinical guidance for the Aescuris coding assistant?
Clinical guidance is provided by Dr. med. Christian C. Schmidt, a specialist in general medicine and anaesthesiology with more than 20 years of practice experience and co-founder of Aescuris. Workflows, review rules and the way suggestions are presented are refined iteratively together with pilot practices.
