OBJECTIVES: To evaluate the most frequent outpatient care physiotherapy services provided for musculoskeletal and connective tissue diseases and determine the total health care expenses of them. METHODS: Data were derived from the countrywide database of Hungarian Health Insurance Administration (HHIA), based on official reports of outpatient care institutes in 2008. The total numbers of different physiotherapy services were determined by selecting the reported specific diagnoses codes and counting the number treatments provided for that specific diagnosis code. The different types of treatment codes are listed in the chapter of the Guidelines of HHIA for `Physiotherapists, massage-therapists, conductors and other physiotherapy practices`. The musculoskeletal and connective tissue diseases are listed in the International Classification of Diseases (ICD) with code of M00-M99. RESULTS: The total number of the 151 different types WHO-classified physiotherapy services was 29045736 in the year of 2008, 17455468 (60.1%) of them with the ICD code group M00-M99. The services with highest incidence are the followings: 1) ultrasound therapy 2011189 (11.52%); 2.) iontophoresis 1586016 (9.08%); 3) massage therapy with hand l946364 (5.42%); 4) middle frequency electrotherapy 932474 (5.34%); and 5) passive motion therapy on multiple limbs 821314 (4.7%).  The number of the 20 most frequent types of therapies was 14285957, which is the 81.84% of all cases. The total health insurance reimbursement of the treatments of diseases with ICD code M00-M99 was 4.713 billion Hungarian Forint (18.76 million EUR). CONCLUSIONS: The 60.1% of the total number of physiotherapy services were provided for the treatments of diseases with ICD code M00-M99, supporting the notion that physiotherapy is dominantly used in the treatment musculoskeletal diseases. The financial cost of the outpatient care physiotherapy of diseases with ICD code M00-M99 exceeded the 50% of the total budget provided for physiotherapy services.
