Knee Arthroscopy to Wash Out Infection

Washington, DC rates for HCPCS 29871

A camera and irrigation instruments are placed into the knee through small punctures so the joint can be flushed out and infected fluid, pus, and debris removed. Clearing the infection quickly matters because pus destroys joint cartilage within days. Antibiotics are given as well, but they cannot clear infected joint fluid on their own.
