What conservative treatment is required before Hip Replacement?

Most insurers require 6–12 weeks of physical therapy, at least one corticosteroid or other injection, and documented activity modification. Your orthopedic surgeon's prior auth request must include dates, session counts, and progress notes.

What happens if my Hip Replacement prior authorization is denied?

Request the denial in writing with specific criteria not met. Submit a peer-to-peer review request. Gather all PT records, injection notes, and imaging. File a formal appeal. If denied again, request an external independent review - this is your right under the ACA.

Will I get multiple bills for Hip Replacement?

Yes. Three separate bills: facility fee (DRG-based, includes the implant), surgeon fee (professional), and anesthesia. The hardware/implant is bundled into the facility DRG - it is not a separate patient charge under most billing arrangements.

Yes - Hip Replacement is covered by insurance. Whether you owe anything depends on your plan type, deductible status, and a few billing rules that catch patients off guard.

Is Hip Replacement Covered by Insurance? (2026 Guide)

Q: Is Hip Replacement covered by insurance?

Yes, when medically necessary. Most plans require documented failure of conservative treatment (physical therapy, injections) before approving hip replacement. Prior authorization is almost always required.

Yes - Hip Replacement is covered by insurance when it is medically necessary and conservative treatment has been tried and failed. It is an elective major surgery, so prior authorization is almost always required before your insurer will pay.

Getting approved isn't the finish line - knowing what you'll actually owe is. Here's how to find that out before the surgery, not after.

Quick answer:

A hip replacement is four separate bills - and one of them keeps arriving for weeks after the surgery.

Your personalized cost report includes:

✓ Why a short inpatient stay adds a facility day-rate on top of the surgery itself
✓ The separate anesthesia bill that can be out-of-network even at an in-network hospital
✓ How physical therapy is billed - per visit, for weeks - and the plan limits to confirm first
✓ The questions to ask before scheduling, including whether you qualify for a lower-cost surgery center
✓ A real patient billing breakdown, line by line

Medically necessary Hip Replacement (after failed conservative treatment): Covered - deductible + coinsurance apply
Prior authorization: Required - must document failure of conservative therapy
Bills you'll receive: 3 (facility + surgeon + anesthesia)
The implant: Bundled into the facility DRG - not billed to you separately

Conservative Treatment Requirement

Before approving a hip replacement, virtually all commercial plans and Medicare Advantage plans require documented evidence that you tried conservative treatment first:

Physical therapy: Typically 6–12 weeks of documented, supervised PT
Injections: Corticosteroid or hyaluronic acid injections for the hip
Activity modification: Evidence of attempted weight management or activity changes
Imaging documentation: X-rays or MRI showing the severity of degeneration

The most common denial reason for hip replacement prior auth: insufficient documentation of conservative treatment. Your orthopedic surgeon's notes, PT records, and prior imaging need to clearly support that non-surgical options were tried and failed.

Site-of-Service Matters in 2026

CMS is progressively removing major joint procedures from the Medicare inpatient-only list, allowing hip replacement to be performed outpatient or in ambulatory surgery centers. Commercial plans are following this trend and actively steering patients toward lower-cost settings.

What this means for you:

An ASC setting costs your plan less - and may cost YOU less in coinsurance
Some plans tier facilities and apply higher cost sharing at HOPDs
Confirm whether your surgeon performs hip replacement at an ASC and whether it changes your out-of-pocket
