Rückforderungen und Refund-Rework durch falsche EBM-Kodierung

Updated: Feb 20263 verified sources

Definition

Manual EBM coding errors during the 2025 reform transition create systematic overbilling and underbilling. Common errors: (1) applying old EBM codes to new devalued services, (2) forgetting to apply new flat rates for collection materials, (3) applying incorrect flat-rate amounts (e.g., €2.50 vs. €3.50 for collection), (4) billing devalued services at old rates. When Krankenkassen detect these errors, they reject the claim or demand refund. Laboratories must: (1) identify the error, (2) adjust the claim, (3) resubmit, (4) process refund/reconciliation. Each rework cycle involves 15–45 minutes of staff time (€12–€36 per claim), plus 5–20 day delay in payment. For a mid-sized lab processing 100–150 claims/day, a 5% rejection rate = 5–7 rejected claims/day = 25–35 rework cycles/week = €300–€1,260/week in pure rework cost.

Key Findings

Financial Impact: €15,000–€50,000 annually per mid-sized lab due to: (1) rework labor (5% of billing staff time = €12,000–€20,000/year), (2) delayed refund recovery (5–20 day float × €1,000–€5,000/day claims = €10,000–€100,000 float depending on lab size). Large networks: €100,000–€500,000 aggregate.
Frequency: Continuous (3–8% of all claims during post-reform period, Jan–Dec 2025; declining as processes stabilize). Acute spike expected Jan–Mar 2025 during transition.
Root Cause: Manual coding under time pressure + complex EBM regulatory change = systematic error. No automated validation gates errors before submission. Industry lacks standardized claims-checking protocols.

Gebührendevaluation und Abrechnungslücken bei Laborreformen

€250,000–€500,000 annually per mid-sized laboratory (50-150 tests/day) due to: (1) 15-25% reimbursement devaluation on 40-60% of service portfolio, (2) missed flat-rate billing (estimated €2,000–€5,000/month per lab from unbilled order entry flat rates), (3) manual coding errors requiring rework and refund processing (estimated 5-10 hours/week at €50–€80/hour = €13,000–€41,600/year). Large laboratory networks (200+ daily tests) may lose €1M+/year.

Betriebsprüfung-Risiko durch manuelle EBM-Kodierung und Rechnungsungenauigkeiten

€10,000–€50,000 per lab per audit (typical 3–5 year audit cycle). Conservative estimate: €5,000–€10,000 annual risk provision per lab. Large networks (10+ locations): €50,000–€250,000 aggregate exposure. Interest and penalties add 5–10% on top of principal recovery amounts.

Manuelle Kodierungskapazität und Verzögerung bei Rechnungsverarbeitung (Time-to-Cash Drag)

€40,000–€150,000 annually per lab in delayed cash flow (opportunity cost at 5% annual borrowing rate on AR float). Staffing cost: €25,000–€80,000/year (1–1.5 FTE at €25k/year loaded cost) spent on manual coding. Network of 10 labs: €400,000–€1.5M/year in combined efficiency loss. AR acceleration of 10–20 days = €50,000–€200,000 working capital freed per mid-sized lab.
