Legal analysis: the full English name of DIP is: Big Data Diagnosis-Intervention Packet; the full Chinese name is Big Data-based Payment by Points for Diseases.DIP is an automatic grouping of diagnosis + operation based on full sample data. Based on objective data, disease categories are formed directly by the natural combination of primary diagnosis and associated surgical operations.

Legal basis: "Pilot Work Program for Total Budget and Payment by Value of Disease Types in Regional Point Methods"

Article 2 DIP is based on big data technology, and in accordance with the unified determination of the catalog database of value of disease types at the national level, the criteria for the division of core and comprehensive disease types, etc., and through the regional analysis of the data of disease cases of the last three years in the fixed-point medical institutions, and based on the main clinical diagnosis codes (ICD-10) and surgical operation codes, DIP is based on the objective data, which is the natural combination of the main diagnoses and associated surgical operations. Based on the natural combination of clinical major diagnosis codes (ICD-10) and surgical operation codes (ICD-9-CM-3), similar disease diagnoses are categorized, and then combined with different treatment modalities to establish a disease combination system.

The third DIP is an upgraded version of the previous single-disease payment method. The previous single-disease coverage is limited (once it contains complications and comorbidities, the single-disease exit mechanism is adopted), and it is not easy to promote. The big data-based DIP can largely circumvent this drawback, and the DIP score payment is mainly applicable to the settlement of inpatient medical expenses, while the adaptability and scalability of DIP can be explored and applied to the establishment of outpatient payment standard and the reform of medical institutions' charging standard.
