Question juridique clé
Whether the treatment performed in 2004 was uneconomic under Art. 56 KVG and justified reimbursement of CHF 47,469.90.
Solution extraite
The appeal failed; the challenged amount remained owed because the statistical comparison method and the adjusted comparison group did not disclose any legally relevant practice particularities warranting a higher tolerance margin.
Motifs extraits
The choice and modification of the comparison group concerns evidence, not a change of claim basis. The new group of ten comparable general practitioners met the criteria of minimum size, homogeneity, geographic area, and patient mix. The appellant did not substantiate practice-specific factors justifying a tolerance level above 130 index points.
