Every Spitex visit in Switzerland is paid for by up to three different parties: the mandatory health insurer, the canton or municipality, and the patient. This three-way division — the **Kostensplitt** — is one of the most misunderstood aspects of Swiss home-care operations, and getting it wrong is a leading cause of billing disputes, rejected claims, and revenue leakage. Understanding who pays what, and documenting each share correctly at the source, is the foundation of a healthy Spitex balance sheet.
The Three Pillars of Home-Care Funding
Swiss outpatient nursing care ordered by a physician is financed under the framework of mandatory health insurance law (**KVG/OKP**). The insurer pays a fixed contribution per care category, set at the federal level. Under KLV Art. 7a, these statutory hourly rates are CHF 76.90 for assessment and advice (Cat. a), CHF 63.00 for examination and treatment (Cat. b), and CHF 52.60 for basic care (Cat. c). These contributions, however, deliberately do not cover the full cost of care delivery. The remainder is split between the public sector and the patient.
The second pillar is **cantonal residual financing** (Restfinanzierung). Cantons — or, depending on cantonal law, municipalities — are obliged to cover the costs that remain after the insurer contribution and the patient share are deducted. How this residual financing is calculated, capped, and paid out varies significantly from canton to canton. In practice, cantons define their own standard cost norms and deficits to bridge, meaning reimbursement calculations and administrative clearing routes differ depending on whether a patient resides in Zurich, Bern, or Vaud. For a Spitex organization operating across cantonal borders, this means the same care act can produce different funding splits depending on where the patient lives.
The third pillar is **patient participation**. Patients contribute to the cost of their nursing care up to a legally defined daily maximum. Under KVG Art. 25a Abs. 5, the federal patient participation is capped at a maximum of 20% of the highest insurer contribution (currently CHF 15.35 per day), with several cantons subsidizing or eliminating it entirely. On top of this care-specific participation, the usual insurance deductibles and co-payments apply to the insurer-financed share.
Why the Split Is Hard to Get Right
On paper, the Kostensplitt is a formula. In practice, it is a moving target:
- The applicable insurer contribution depends on the **KLV care category** of each recorded service, so a misclassified care act shifts money between the wrong payers.
- Residual financing rules differ by canton and sometimes by municipality, including different tariff ceilings and settlement procedures.
- Patient participation must be tracked cumulatively against the cap, not calculated per visit in isolation.
- Corrections after invoicing require reopening settled periods with three different counterparties instead of one.
Organizations that manage this with spreadsheets and retrospective paper records spend disproportionate administrative effort reconciling the three flows — and absorb the losses silently when reconciliation fails.
How a Digital Care Ledger Computes the Split
A structured **Care Ledger** approach removes the guesswork by anchoring the Kostensplitt to the point of care. Every recorded service carries its care category, duration, and the responsible caregiver's qualification from the moment it is documented. When the billing period closes, the platform computes the three shares deterministically: the insurer contribution from the recorded categories, the patient participation tracked against the statutory cap, and the residual amount attributed to the canton or municipality according to the configured cantonal rules.
Because the split is derived from locked, timestamped service records rather than reconstructed afterwards, each payer receives a statement that traces every franc back to a documented visit. Disputes shrink from arguments about what happened to a simple review of the ledger.
What Care Leaders Should Take Away
The Kostensplitt is not just a finance topic — it is a documentation topic. The quality of the split is decided at the bedside, when the care act is recorded and categorized, not at month-end when the invoices are drafted. Organizations that treat funding attribution as a natural byproduct of good point-of-care documentation close their books faster, defend their claims with confidence, and protect the revenue that finances tomorrow's care.
