Summary & Overview
HCPCS G9224: Documentation of Medical Reason for Not Performing Foot Exam
HCPCS Level II code G9224 identifies documentation of the medical reason for not performing a foot exam (for example, bilateral foot or leg amputation). Nationally, this code supports accurate clinical records and claims when standard foot screening or exam components cannot be completed for valid medical reasons. Proper use of the code preserves the clinical narrative and billing integrity for preventive and chronic care services that include foot exams as a quality measure.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code's clinical purpose, common sites of use, and how it fits into ambulatory documentation workflows. The publication outlines benchmarking considerations, common billing contexts, and potential policy or payer documentation expectations relevant to national coverage and quality reporting. This summary is intended to clarify when G9224 is appropriate and what stakeholders can expect when the foot exam component is not performed due to documented medical reasons.

Clinical & Coding Specifications
Clinical Context
A typical patient is a primary care or endocrinology clinic patient with diabetes mellitus undergoing an annual wellness visit or diabetes follow-up. During the visit the clinician documents that a comprehensive foot exam could not be performed because the patient has bilateral lower-extremity amputations above or below the knee, or bilateral foot amputations preventing inspection, sensory testing, pulses, and monofilament testing. The clinical workflow includes: review of history (diabetes duration, neuropathy, peripheral arterial disease), inspection of residual limbs and prosthetic interfaces, assessment of healing at amputation sites, medication reconciliation, and counseling. The provider documents the specific medical reason for not performing the standard foot exam and uses G9224 to report the documentation of that medical reason in the chart as part of quality reporting or encounter coding requirements.
Coding Specifications
| Modifier | Description | When to Use |
