The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Extracorporeal shockwave therapy for refractory greater trochanteric pain syndrome.


The greater trochanter is the bony bump on the outer side of the hip. This area may become painful following hip surgery or as a result of inflammation of the fluid-filled sac (bursa) that allows smooth motion between bones and tendons or muscles. Such inflammation (bursitis) is often caused by minor repetitive trauma or a direct injury.

In extracorporeal shockwave therapy, a machine is used to deliver sound waves to the painful area. It is not known exactly how this works, but it is thought that it might stimulate healing.

Coding recommendations

ESWT for greater trochanteric bursitis:

T62.8 Other specified operations on bursa

Y53.2 Approach to organ under ultrasonic control (if used)

Z76.3 Trochanter of femur

The NHS Classifications Service has advised NICE that currently these are the most suitable OPCS-4 codes to describe this procedure. The OPCS-4 classification is designed to categorise procedures for analysis and it is not always possible to identify a procedure uniquely.
