The diagnosis code you have there is RT hip trochanteric bursitis. Why would 3 major joint injections with US be done for a single joint?
We would need more information to understand your question. Are they performing major joint injections on bilateral hips and one knee or one shoulder for example? If so, you would need to assign the correct diagnosis and laterality to each injection for starters. If it is bilateral say, in both hips one line would have a modifier 50 on it for the hips. If there was an additional like the knee or shoulder you would do a second line with that.
Links below are couple other discussions on it. Some payers won't allow 3 at the same time. Some will. Coding can vary depending on health plan.
Example of a MAC discussion on bilateral indicators, this one is good because it has joint injections as the example.
Noridian had a video about it but it's older and may not apply nowadays.
