W3712: total hip replacement code
A practical explanation from Mr Mohamed Mussa, Consultant Hip and Knee Surgeon.
Search all procedure codes →What this code describes
W3712 describes a primary total hip replacement. It is a starting point for an authorisation discussion when a hip is being replaced for the first time. The final code depends on the planned operation: previous surgery, bone reconstruction or a revision may require a different code.
Your clinical team must confirm the planned procedure. Your insurer must confirm authorisation for your surgeon, hospital and treatment.
Questions to ask before treatment
- Is this a routine primary replacement or a complex reconstruction?
- Does my authorisation include the chosen hospital and surgeon?
- If robotic assistance is proposed, what additional approval is needed?
Keep your authorisation reference and check any excess, shortfall or separate hospital, imaging and anaesthetic charges. If your treatment plan changes, ask whether authorisation needs updating.
