HCPCS G4028: Podiatry MIPS Specialty Set

HCPCS Level II code G4028 identifies the Podiatry MIPS specialty set, a quality measurement and reporting construct used for podiatric clinicians engaged in the Merit-based Incentive Payment System. Nationally, this code matters because it ties specialty-specific quality measures to performance reporting and potential payment adjustments under federal value-based programs, influencing how podiatry practices document and report care quality.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what G4028 represents, why it is relevant across payers, and what to expect in terms of measure-set coverage and reporting implications. The publication outlines benchmarks and reporting considerations where available, summarizes recent policy updates affecting specialty measure sets, and provides clinical context about how podiatry-specific measures integrate with broader quality reporting efforts.

This national summary is intended to orient administrators, compliance officers, and clinicians to the role of G4028 in quality reporting. Data not available in the input is noted where applicable; the focus remains on clarifying the code's purpose, payer coverage scope, and the types of content readers will find in the full publication.

Billing Code Overview

HCPCS Level II code G4028 denotes the Podiatry MIPS specialty set. This code indicates a specialty-specific measure set associated with podiatry clinicians participating in the Merit-based Incentive Payment System (MIPS).

Service type: Quality measurement and reporting for podiatry clinical practice
Typical site of service: Outpatient podiatry clinics and ambulatory care settings

Clinical Context

A 62-year-old patient with long-standing diabetes and peripheral neuropathy presents to a podiatry clinic with a nonhealing plantar ulcer and associated pain. The podiatrist evaluates wound status, performs debridement, assesses vascular supply, and documents risk factors for poor healing. The practice participates in MIPS and reports the podiatry specialty MIPS quality and improvement activities; G4028 is used for MIPS specialty set reporting and administrative tracking related to podiatry performance measures. Typical workflow: outpatient podiatry visit in a clinic or ambulatory surgical center; history and focused exam; wound care and debridement as indicated; documentation of quality measures (e.g., ulcer assessment, offloading plan, neuropathy screening, glycemic control review); coding and submission of G4028 for specialty-set reporting alongside procedural and E/M codes. Typical site of service: ambulatory clinic / podiatry office or ambulatory surgical center when minor procedures are performed.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when work required is substantially greater than typical for the reported service and additional documentation supports increased complexity.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`E11.621`	Type 2 diabetes mellitus with foot ulcer	Diabetic foot ulcers are a primary indication for podiatric wound care and MIPS specialty reporting.
