abstract="The absolute necessity of checking documentation received was reported on, as well as the fact that the legislature cannot assume that one can draw conclusions from one year about the following year. It was shown that the introduction of new methods can considerably affect diagnosis statistics, and pointed out that easier research into complications was one positive effect of the--externally induced--more detailed formulation of medical reports. Since, in our 10,000-patient orthopedic-traumatologic clinic, we had to state every fourth ICD-9 figure including the V-classification, it would not be possible in our case to cover the entire hospital with just a few code numbers. Furthermore, it has so far proved right, in spite of the stipulation to use ICD-9, to perform basic documentation using our in-house code. This appears indispensable to us, particularly considering the error rate when decoding ICD-9 data.<p /><p>Language: de</p>",
