Compared to other medical specialties plastic surgery coding is challenging. Various factors like the complexity of procedures, lack of standardization, limited insurance coverage, and documentation requirements make it challenging to receive accurate insurance reimbursements. It’s difficult to share generalized coding guidelines for plastic surgery due to the vastness of medical procedures. In this article, we shared coding guidelines for a few sets of plastic surgery codes. Sharing the complete list of plastic surgery codes and their guidelines is not possible due to copyright issues. Note that American Medical Association (AMA) holds the rights for CPT codes in plastic surgery and we shared some basic plastic surgery coding guidelines for provider education purposes only.

Basic Plastic Surgery Coding Guidelines

We shared coding guidelines for various plastic surgery procedures namely, adjacent tissue transfer, myocutaneous flaps; oral, facial, and maxillofacial reconstruction; rhinoplasty/nasal reconstructive surgery; and cosmetic procedures. Some basic plastic surgery coding guidelines are as follows:

1. Adjacent Tissue Transfer (CPT Code 14000-14302)

CPT codes 14000-14302 are used to describe various types of skin grafts and flap procedures commonly performed in plastic surgery. Coding guidelines while using adjacent tissue transfer are as follows:

• Identify the type of tissue transfer: Before coding, it is important to identify the type of tissue transfer that was performed. This can include local flaps, advancement flaps, rotation flaps, transposition flaps, or free flaps.
• Determine the size of the tissue transfer: The size of the tissue transfer is an important factor in coding these procedures. This can be determined by measuring the length and width of the flap, or by calculating the surface area of the graft.
• Consider the complexity of the procedure: The complexity of the procedure can also impact the code used. More complex procedures may require higher-level codes, while simpler procedures may be coded at a lower level.
• Use the appropriate modifier: Depending on the circumstances of the procedure, certain modifiers may need to be used to accurately reflect the services provided. For example, modifier -59 may be used to indicate a distinct procedural service.
• Document the procedure in detail: Accurate and detailed documentation of the procedure is essential for proper coding. This should include a description of the technique used, the size of the tissue transfer, any complications or additional procedures performed, and any modifiers used.

2. Myocutaneous Flaps (CPT Code 15570- 15758)

Accurate coding of myocutaneous flap procedures requires careful consideration of the location, size, and complexity of the defect, the type and extent of the flap used, and any additional procedures performed. Following are plastic surgery coding guidelines applicable to myocutaneous flaps:

• Code selection: To select the appropriate code for a myocutaneous flap procedure, the plastic surgeon must determine the location, size, and complexity of the defect, as well as the type and extent of the flap used. The CPT code range 15570-15758 includes codes for different types of myocutaneous flaps, such as muscle flaps, fasciocutaneous flaps, and myocutaneous island flaps. The surgeon must choose the code that best describes the procedure performed.
• Documentation: Accurate documentation is essential for the proper coding of myocutaneous flap procedures. The surgeon must document the location, size, and complexity of the defect, the type and extent of the flap used, and any other procedures performed during the same surgical session. The documentation must also include the surgeon’s rationale for the choice of the specific flap, any complications encountered, and the final outcome.
• Multiple procedures: When multiple procedures are performed during the same surgical session, the surgeon must ensure that the codes selected accurately reflect the complexity and extent of the services provided. When coding for myocutaneous flap procedures, the surgeon must consider the codes for any additional procedures performed, such as debridement, tissue transfer, or reconstruction.
• Unplanned procedures: In some cases, the surgeon may encounter unforeseen circumstances during the procedure that require the performance of additional services. In these cases, the surgeon should document the circumstances and the additional services provided, and select the appropriate code(s) for the additional procedures.

3. Oral, Facial, and Maxillofacial Reconstruction (CPT Code 21120- 21296)

Oral, facial, and maxillofacial reconstruction codes cover a wide range of surgical interventions and procedures aimed at restoring or improving the function and appearance of the mouth, face, and jaw after trauma or disease. Following are some of the key coding guidelines for these CPT codes:

• Code selection: CPT codes 21120-21296 are organized based on the type of procedure performed, such as bone grafting, osteotomy, or reconstruction of the soft tissues. It is important to select the appropriate code based on the specific procedure performed and the body part involved.
• Time-based codes: Some codes in this range are time-based, meaning that they are reported based on the amount of time spent performing the procedure. For these codes, it is important to document the start and stop times of the procedure accurately.
• Use of anesthesia codes: Procedures performed under anesthesia may require the use of anesthesia codes in addition to the procedure codes. It is important to report the correct anesthesia codes based on the type and duration of anesthesia used.
• Documentation of medical necessity: Accurate and detailed documentation of the medical necessity for the procedure is essential to support the use of these codes. This includes a description of the patient’s condition, the specific problem being addressed, and the reason why the procedure is necessary.
• Use of modifiers: Modifiers may be used with these codes to indicate specific circumstances or conditions that may affect payment. For example, modifier 50 may be used to indicate that the procedure was performed bilaterally, while modifier 51 may be used to indicate that multiple procedures were performed during the same session.

4. Rhinoplasty/Nasal Reconstructive Surgery (CPT Code 30400- 30520)

When coding for Rhinoplasty/Nasal Reconstructive Surgery in plastic surgery, it is important to follow certain coding guidelines to ensure accurate billing and avoid potential errors or denials. Following are basic plastic surgery coding guidelines applicable to rhinoplasty/nasal reconstructive surgery:

• Code selection: Each code in this range represents a specific type of procedure or technique used during the surgery, so it’s important to choose the correct code that best represents the work performed. For example, if the surgery involves altering the nasal tip, CPT code 30400 may be used, while if the surgery involves altering the nasal bones, CPT code 30420 may be used.
• Documentation: In order to accurately code for Rhinoplasty/Nasal Reconstructive Surgery, the operative report should include detailed information about the specific techniques used, the areas of the nose that were operated on, and any additional procedures performed (such as septoplasty or turbinate reduction). It is also important to document any complications or unexpected findings during the surgery.
• Use modifiers appropriately: Depending on the specific circumstances of the surgery, certain modifiers may need to be added to the CPT code to indicate that additional work was performed or that the surgery was more complex than usual. For example, if the surgery involved a revision of a previous rhinoplasty, the modifier -22 may be added to indicate that the surgery was more complex than a typical Rhinoplasty/Nasal Reconstructive Surgery.

5. Cosmetic Procedures (CPT Code 11950- 17380)

Medicare and Medicaid typically do not cover cosmetic procedures in plastic surgery, as they are considered elective or non-essential procedures. However, there may be some exceptions in cases where the procedure is deemed medically necessary for functional or reconstructive purposes, such as breast reconstruction after a mastectomy. Commercial insurance companies may offer coverage for some cosmetic procedures, but this varies depending on the policy and the individual’s specific situation. In general, cosmetic procedures that are considered purely cosmetic and not medically necessary are unlikely to be covered by insurance.

Proper documentation, selecting the correct code, using modifiers when necessary, establishing medical necessity, documenting preoperative and postoperative care, avoiding unbundling, and complying with LCDs are all important factors to consider when coding for cosmetic procedures. Following are some guidelines to follow when coding for cosmetic procedures in the CPT code range 11950-17380:

• Medical Necessity: As mentioned above, medical necessity is an essential factor in coding for cosmetic procedures. Documentation should clearly establish the medical necessity of the procedure, including the patient’s symptoms and the physician’s determination that the procedure is necessary for the patient’s well-being.
• Multiple procedures: When multiple procedures are performed during a single session, each service should be appropriately documented and coded. The highest-valued procedure should be listed first, and the subsequent procedures should be listed in descending order of value.
• Preoperative and postoperative care: Preoperative and postoperative care should be appropriately documented, including any medications or supplies used during the procedure or recovery period. This documentation helps ensure accurate coding and proper reimbursement.
