So, can we get started?
CPT Code 27130 – Description
CPT code 27130 is from the ‘Repair, Revision, and/or Reconstruction Procedures on the Pelvis and Hip Joint’ code range. It is maintained by the American Medical Association (AMA) and covers total hip arthroplasty.
It involves surgically replacing the hip joints with artificial hip joints or prostheses. The surgeon replaces the acetabular and femoral components with or without using an allograft or autograft.
Scenarios Where CPT Code 27130 is Applicable
The descriptor of CPT code 27130 seems straightforward. Let’s take a look at a few clinical scenarios to gauge where it applies:
Hip Dysplasia Leading to Early Osteoarthritis
Picture this: A 40-year-old female patient with a history of developmental dysplasia of the hip (DDH) visits the clinic. She complains about an increase in hip pain and functional limitations.
Radiographs reveal early but significant osteoarthritis secondary to the abnormal hip joint anatomy from her dysplasia. Even though she is young, the severe pain and functional limitations warrant surgical intervention.
Therefore, the orthopedic surgeon performs a total hip arthroplasty (CPT code 27130). This procedure addresses the abnormal acetabular morphology during the replacement process. Ultimately, it helps ensure proper seating of both the femoral and acetabular prosthetic components.
Fracture of the Femoral Neck
Consider this: A 70-year-old female fractured her hip, and the bone fragments shifted following a fall.
The orthopedist believes that open reduction and internal fixation are less likely to provide a long-term outcome. The reason? The patient’s age, activity level, and the displaced nature of the fracture.
As a result, the orthopedic surgeon performs a total hip arthroplasty (CPT code 27130). During the procedure, the surgeon removes the fractured femoral head and neck and replaces it with a prosthetic femoral stem and head. Moreover, the surgeon prepares and fits the acetabulum with a prosthetic cup.
Avascular Necrosis of the Femoral Head
Imagine this: A 50-year-old male patient with a history of long-term corticosteroid use visits the orthopedic clinic. He complains of a progressive increase in pain and stiffness in his left hip.
MRI scans confirm avascular necrosis (AVN) of the femoral head, with significant articular surface collapse. The orthopedist believes that surgical intervention is the ideal solution, as non-operative management may lead to progressive pain and disability.
Therefore, the orthopedic surgeon performs a total hip arthroplasty (CPT code 27130). During the procedure, the surgeon replaces the necrotic femoral head and neck with a prosthesis. Moreover, the surgeon revises the acetabulum with a prosthetic component to create a stable and pain-free joint.
Applicable Modifiers for CPT Code 27130
Are you having trouble deciding which modifier to apply? It’s time to say goodbye to all your challenges. Here’s a list of all modifiers that apply to CPT code 27130:
Modifier 50
Append modifier 50 when the surgeon performs total hip arthroplasty on both hips during the same surgical session.
Modifier 51
There may be scenarios where the surgeon performs total hip arthroplasty in conjunction with other surgical procedures on the same day. When this happens, modifier 51 is your ticket to receive rightful reimbursements.
Modifier 59
How to avoid unnecessary bundling of services? Append modifier 59 to CPT code 27130. It indicates to the payer that the total hip arthroplasty is a distinct, separately reimbursable procedure from other services rendered on the same day.
Modifier 78
What happens when the total hip replacement surgery is related to another previously performed surgery whose global period is still active? You append modifier 78 to ensure coding specificity.
Modifier 79
It is similar to modifier 78. However, there is a distinction. You can append modifier 79 to CPT code 27130 when the return to the operating room for the total hip arthroplasty is unrelated to a previously performed surgery.
Modifier RT
Append this modifier when the surgeon performs total hip arthroplasty on the right hip.
Modifier LT
Use modifier LT when the surgeon performs total hip arthroplasty on the left hip.
Modifier AS
What if a non-physician practitioner (NPP) performs total hip arthroplasty under the supervision of a physician? You append modifier AS to CPT code 27130.
CPT Code 27130 – Billing & Reimbursement Guidelines
Do you want to improve your billing game for CPT code 27130? If yes, don’t skip this section! Discussed below are the billing and reimbursement guidelines for total hip arthroplasty:
Demonstrate Medical Necessity
If there is one medical requirement that serves as the backbone of medical billing, it is establishing medical necessity. No matter the insurance payer and regardless of the procedure, you will get paid only if the performed procedure is medically necessary.
So, how can you demonstrate it for CPT code 27130? It requires thorough documentation of the patient’s hip pain, functional limitations, and diagnostic findings. Additionally, include any unsuccessful attempts at conservative treatment. If the physician did not make any attempts, clearly state the reasons.
Ensure Comprehensive Documentation
Focus on documentation completeness and accuracy. It should include the following:
- The patient’s medical history and physical examination findings.
- Diagnostic reports, such as MRI, CT scan, or X-ray. The report findings should demonstrate the severity of the hip joint condition.
- Details of the previous non-surgical treatments (if any) and their outcomes.
- Date and time of the total hip arthroplasty.
- Operating notes detailing the approach, implants used, and any complications.
- Discharge summary of the patient’s stay at the hospital. It should include rendered procedures, medications, and discharge instructions.
Use Appropriate Modifiers
Modifiers are a key part of billing CPT 27130. For instance, you must specify whether the surgeon performed total hip arthroplasty bilaterally (modifier 50), on the left hip (modifier LT) or the right hip (modifier RT).
Some other modifiers that apply to this procedure include 51, 59, 78, 79, and AS. You can check out the ‘Applicable Modifiers for CPT Code 27130’ for a detailed overview of the appropriate use of modifiers.
Review Payer-Specific Guidelines
Typically, Medicare covers CPT code 27130 if it is medically necessary. Some eligible conditions include avascular necrosis, severe osteoarthritis, or certain fractures that meet their criteria.
You can review the Medicare Physician Fee Schedule (MPFS) to determine the reimbursement rate. However, the rate may vary based on the place of service (POS) and the state of your practice.
You can refer to the Medicare Administrative Contractors’ (MACs) Local Coverage Determinations (LCDs) since these provide specific coverage criteria and documentation requirements in your jurisdiction.
But what happens if the patient is enrolled with a private payer? Coverage policies may vary widely across commercial payers. Prior authorization is often required, and payers may have specific criteria for demonstrating medical necessity. Therefore, you must communicate with the payer and strive to understand and comply with the payer-specific requirements.
Summary
Phew! With so many details to follow through, things often seem complicated. However, not if we have an overview of the key takeaways. Thus, before we conclude, let’s quickly revisit everything.
First came the descriptor. CPT code 27130 covers the total hip arthroplasty.
Second, the clinical scenarios: fracture of the femoral neck, hip dysplasia leading to early osteoarthritis, and avascular necrosis of the femoral head.
Next, we discussed all applicable modifiers, including 50, 59, 78, 79, LT, RT, and AS.
Finally, we explained the billing and reimbursement guidelines for reporting total hip arthroplasty. Hopefully, you will streamline your collections after reading this ultimate guide to CPT code 27130. But if you need professional help, outsource orthopedic billing services to MediBillMD.
