Modifiers play a vital role in medical billing. These are two-digit codes used to explain the services provided by the healthcare provider without changing the primary procedure codes. The correct use of modifiers can help you avoid billing errors and secure full reimbursement for your services.
Hence, we have decided to explore split surgical care modifiers in our blog today. In this read, you will find out all the essential details about modifier 54, from its correct applications to accurate billing guidelines. So, continue reading if you are curious about this modifier.
Modifier 54 – Description
Modifier 54 is a split surgical care modifier used to refer to the intra-operative portion of the surgery only. It is used when one physician performs surgery and another qualified healthcare professional renders preoperative or postoperative care services.
Let’s break down this definition in simple words:
Most surgical procedures have a global period of 10 or 90 days, depending on whether the surgery was minor or major. This global surgical package includes payment for preoperative, intraoperative, and postoperative services. However, if intraoperative services are provided by one healthcare provider and the patient goes to another healthcare provider for postoperative services, then, to bill these intraoperative services, the provider will apply modifier 54. It will explain to the payer that he was only involved in the actual surgery.
This is also known as “split surgical care”, when surgical care is split between various healthcare providers. Each provider reports only the portion of their service using accurate split care modifiers (54, 55, and 56).
Scenarios Where Modifier 54 is Applicable
Let’s have a look at a couple of real-life scenarios where healthcare providers are successfully appending modifier 54 to bill their respective services.
Emergency Trauma Surgery
Suppose a 25-year-old man is brought to a trauma center with a fractured femur after an accident. The orthopedic surgeon available in the emergency department at the hospital performs an open reduction and internal fixation surgery.
After the surgery, the patient is transferred back to his local physician for postoperative follow-up and recovery care. The surgeon bills the procedure with modifier 54 because he only performed the surgery.
Surgery for a Traveling Patient
Suppose a 28-year-old woman visits her relative in Texas during the holidays. During the visit, she suddenly feels severe abdominal pain and fever. She is rushed to the emergency department, where imaging tests confirm acute appendicitis. A general surgeon at the hospital performs an emergency laparoscopic appendectomy to remove the inflamed appendix.
After the surgery, the woman plans to return to her hometown, where she will take all postoperative services, including follow-up visits and recovery monitoring, from her primary care physician back home. Since the operating surgeon only performed the surgical procedure and did not provide postoperative care, he can report the appendectomy CPT code with modifier 54 for billing and reimbursement.
Modifier 54 – Billing Guidelines
The following are some of the key billing guidelines that you must follow while billing with modifier 54:
Document the Transfer Agreement
If the surgeon assigns another physician to handle the follow-up care, what will serve as evidence of the service transfer? The proof is a formal document where the surgeon agrees to transfer postoperative care to another physician. This formal document is particularly required by Medicare and other commercial insurers.
The following details must be included in this document:
- The physician will provide details of postoperative management.
- The date of the formal, written transfer of care.
- Confirmation that both providers agree to the arrangement.
Furthermore, you must mention the following details in your paperwork while submitting claims with modifier 54.
- The patient’s medical history, condition, and symptoms.
- The patient’s identification information, such as the name and policy number.
- The date of surgery.
- Details of the surgery. E.g., the number of incisions made, site operated, etc.
- Follow-up care notes for the service provided.
- The exact date of the transfer of care.
Ensure Appropriate Use of 54
Modifier 54 is used when a surgeon performs the surgical part of a procedure and does not offer the preoperative or postoperative care covered by the global surgical package. This modifier is only applied to surgical procedure HCPCS/CPT codes that have a 10- or 90-day global period.
The surgeon appends this modifier to indicate that he is billing solely for intraoperative services and completely shifting critical care services to another clinician.
Avoid Inappropriate Usage of 54
The insurance payer will deny your payment if you do not follow the accurate billing guidelines for modifier 54. Here are some inaccurate uses of this modifier.
- When appended to a surgical code that does not have a global period.
- When appended to a surgical code that has a global period other than 10 or 90.
- When the provider involved in postoperative care belongs to the same group practice.
- When appended to an Evaluation and Management (E/M) procedure code.
- When appended by an assistant surgeon to indicate assistance during surgery.
Know the Reimbursement Rate
The payer typically reimburses claims with modifier 54 at 70% to 80% of the allowed amount. This percentage shows that the payment is specifically for the surgery and excludes reimbursements for preoperative and postoperative care. However, you must check the payer’s policy manual to confirm 54’s reimbursement rate, as it varies across payers.
Conclusion
Let’s do a quick recap of modifier 54. The modifier indicates that the surgeon has only performed the intraoperative part of a procedure, with preoperative or postoperative care being handled by another licensed healthcare professional. You must adhere to proper billing guidelines for modifier 54 to ensure clean claim submission and accurate payment collection.
