Summary & Overview
HCPCS G4027: Plastic Surgery MIPS Specialty Set
HCPCS Level II code G4027 designates the plastic surgery MIPS specialty set, a quality-measure grouping used for performance reporting among plastic surgery clinicians. Nationally, specialty-specific MIPS sets help standardize measurement of clinical quality, patient safety, and care coordination for surgical specialties, influencing public reporting and value-based payment adjustments. This code signals that a clinician is reporting the plastic surgery-focused measures relevant to MIPS.
Key payers in the national context include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what G4027 represents, how it ties to plastic surgery quality measurement, and the typical settings where reporting applies (outpatient clinics, ambulatory surgical centers, and physician offices). The publication provides benchmarks for reporting uptake, summarizes pertinent policy updates affecting MIPS specialty sets, and outlines clinical context for measure selection and application. Where specific data elements are not available in the input, the text will note that those items are not provided.
Billing Code Overview
HCPCS Level II code G4027 represents the Plastic surgery MIPS specialty set. This code is used to identify a specialty-specific quality measure set tied to plastic surgery within the Medicare Quality Payment Program (MIPS) framework.
-
Service type: Quality and performance measurement for plastic surgery clinicians
-
Typical site of service: Performance reporting across outpatient and surgical settings where plastic surgeons practice, including ambulatory surgical centers and physician offices
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult seeking reconstructive or aesthetic plastic surgery services for conditions such as post-traumatic soft tissue defects, breast reconstruction after mastectomy, congenital deformity correction, or elective cosmetic procedures (e.g., rhinoplasty, abdominoplasty). The clinical workflow begins with an initial consultation in an outpatient plastic surgery clinic where history, physical exam, and photographic documentation are obtained. Relevant imaging or prior operative reports are reviewed. Preoperative medical assessment and clearance are completed; informed consent is documented. On the day of service, procedures are performed in an appropriate setting (ambulatory surgical center or hospital operating room) under monitored anesthesia care or general anesthesia. Intraoperative documentation includes procedure performed, technical details, time, personnel, implants or grafts used, and any unusual events. Postoperative instructions, wound care, expected recovery timeline, and follow-up visits are documented. Billing uses the plastic surgery MIPS specialty set represented by G4027 to identify quality reporting and specialty-specific measure mapping for Medicare MIPS attribution and reconciliation.
