Summary & Overview

HCPCS G9225: Foot Exam Not Performed

HCPCS Level II code G9225 denotes that a foot exam was not performed and no reason was provided. This non-procedural reporting code is used in clinical documentation to capture missed or omitted foot examinations during encounters. Nationally, such codes matter for quality measurement, clinical workflow tracking, and administrative records where completeness of preventive and risk-based foot screening is relevant, particularly for populations at risk for foot complications.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code's purpose, its clinical context, and what its use implies for documentation and quality monitoring. The publication outlines benchmarking considerations, typical sites of service, and common modifier practices used alongside the code (listed separately), and provides guidance on interpreting absence-of-service codes in administrative datasets.

The piece is intended for clinicians, coding professionals, compliance officers, and policy analysts seeking concise information on the role of G9225 in clinical documentation and administrative reporting. Data not available in the input is noted where applicable; the focus remains on national implications and practical interpretation rather than jurisdiction-specific guidance.

Service type: Clinical exam omitted
Typical site of service: Outpatient clinic or ambulatory care setting

Clinical & Coding Specifications

Clinical Context

A primary care clinician documents that a scheduled diabetic foot examination was not performed during a chronic care visit. The patient is a 64-year-old with type 2 diabetes and peripheral neuropathy who attends a routine follow-up visit for glycemic control, medication reconciliation, and review of lab results. During the encounter the patient reports severe foot pain from an acute gout flare and is unable to remove footwear due to pain; additionally, the patient is agitated and refuses removal of shoes for the exam. The clinician documents the inability to perform the foot exam, the reason for omission, and proceeds with other components of the visit such as medication management, counseling, and care coordination. The visit is coded for the E/M service provided and the foot exam omission is reported with the HCPCS Level II code G9225 to indicate that the foot exam was not performed and the reason is not given in the record.

Coding Specifications

The following table lists the most clinically relevant modifiers for use in circumstances related to omission, unusual circumstances, or the professional component of procedures. Use is based on standard CMS definitions.

Modifier	Description	When to Use
`23`	Unusual Anesthesia	When significant, medically necessary, and documented anesthesia is provided for a procedure that normally does not require anesthesia.
`52`	Reduced Services	When a service is partially reduced or eliminated at the physician's direction; use when a planned component such as a foot exam is partially performed.
`53`	Discontinued Procedure	When a procedure is started but discontinued due to extenuating circumstances or patient choice.
`54`	Surgical Care Only	When the surgeon provides only the surgical portion of a global service. (Rarely applicable to a non-performed exam but included for completeness in care splits.)
`55`	Postoperative Management Only	When the physician provides only postoperative care. (Applicability is limited for exam omission contexts.)
`56`	Preoperative Management Only	When only preoperative care is provided.
`62`	Two Surgeons	When two surgeons work together as primary surgeons. (Typically not used for a omitted foot exam.)
`AS`	Left Arm or Leg	Denotes laterality when required by payors; use `AS`/other laterality modifiers if a payor mandates.
`CO`	Left Foot or Toe	Denotes specific laterality/region per some payer conventions; use only if payer requires a regional modifier set.
`CQ`	Service furnished as part of a clinical trial	When the visit is related to a clinical trial and the service is billable under trial rules.
`FY`	Billing for charge is for beneficiary not enrolled in Part B	Use for certain Medicare billing circumstances when beneficiary coverage differs.
`QK`	Medical Direction of Two, Three, or Four	When the physician medically directs an assistant at surgery; included for continuity when care teams are involved.
`QX`	Modifier for Assistants — Assistant at Surgery — Qualified Nonphysician	When a qualified nonphysician assistant performs elements of care under direction.
`QY`	Medical Direction of One Assistant	When a physician medically directs one assistant at surgery.

Taxonomy Code	Specialty	Notes
`207Q00000X`	Family Medicine	Common provider for diabetic foot screenings during primary care visits.
`208D00000X`	General Internal Medicine	Frequently performs diabetic foot exams and chronic care management.
`208M00000X`	Endocrinology	Manages diabetes complications and may document foot exams or omissions during endocrine visits.
`231E00000X`	Podiatry	Primary specialists for foot examinations and wound care; may document non-performance reasons.
`207L00000X`	Physician Assistant	Mid-level provider performing routine diabetic foot screenings in many settings.

Related Diagnoses

The input did not include specific ICD-10 codes, so the following are commonly associated diagnoses for patients receiving diabetic foot exams.

ICD-10 Code	Description	Clinical Relevance
`E11.9`	Type 2 diabetes mellitus without complications	Primary diagnosis for routine diabetic foot screening in primary care.
`E11.40`	Type 2 diabetes mellitus with diabetic neuropathy, unspecified	Neuropathy increases risk for loss of protective sensation; foot exams are standard.
`E11.621`	Type 2 diabetes mellitus with foot ulcer	Foot ulcers require inspection; omission of the foot exam may delay ulcer detection.
`L97.909`	Non-pressure chronic ulcer of unspecified part of lower leg, unspecified severity	Lower extremity ulcers prompt detailed foot exams and wound care planning.
`M79.671`	Pain in right foot	Localized foot pain may prevent or preclude completion of a foot exam.
`M79.672`	Pain in left foot	Laterality-specific foot pain affecting ability to perform an exam.
`G62.9`	Polyneuropathy, unspecified	Neuropathy of multiple nerves affects protective sensation; foot exams are preventive.

Related CPT Codes

Common CPT codes that are performed alongside or in the workflow of foot examinations for diabetic patients.

CPT Code	Description	Relationship to This Procedure
`99213`	Office or other outpatient visit for the evaluation and management of an established patient, typically 15 minutes	Often used for routine diabetes follow-up visits during which a foot exam would ordinarily be performed but was not completed.
`99214`	Office or other outpatient visit for the evaluation and management of an established patient, typically 25 minutes	Used for more complex chronic care visits; documents the E/M portion when a planned foot exam was omitted.
`11056`	Debridement of subcutaneous tissue (includes removal of foreign material)	Performed when foot wounds are present; may be scheduled after a foot exam identifies need — relevant when exam not performed and wound care deferred.
`11719`	Trimming of nondystrophic nails, any number	Routine foot care often performed during a diabetes visit; noted when nail care is deferred because exam could not be completed.
`99490`	Chronic care management services, at least 20 minutes of clinical staff time directed by a physician or other qualified healthcare professional, per calendar month	Ongoing management code used when components of care are provided despite omission of an in-person foot exam.
