The price of color ultrasound is set by provincial and regional price departments and health departments according to the actual situation in their respective regions. And the pricing scheme is to provide a basic pricing level according to the different parts examined, and then the pricing is divided into provincial, city and county according to the level of the hospital. The pricing of color ultrasound can be adjusted up or down by about 10% according to the specific situation of the hospital. And these prices are not set in stone, every year the price bureau and the health department will make minor adjustments to the pricing, and each region will develop its own price adjustment plan. The general abdominal ultrasound that is often done clinically is 80 yuan for a system (liver, gallbladder, pancreas and spleen for the digestive system, kidney, ureter, bladder, prostate for the urinary system and uterine adnexa for the reproductive system) in a general hospital. This price point is similar throughout the country. Clinically, the fee varies depending on the part of the body being examined by each patient. For example, an ultrasound examination of the heart is usually around $200. The charge for one superficial organ is about $60. Fetuses are charged differently depending on the time period. The general screening items in the fetal period are about 80 RMB, and the most expensive one is the 4D ultrasound, which is about 300 RMB. Nowadays, the state has required that the list of charges in hospitals be made public and hung in a conspicuous place in the department, so that patients can easily compare them during the examination. So now the price of color ultrasound is transparent in all hospitals.
