Summary & Overview
HCPCS G0037: Assessment/Screening Not Feasible — Patient Unable to Participate
HCPCS Level II code G0037 denotes an attempted assessment or screening that cannot be completed because the patient is unable to participate and no knowledgeable informant is available. The code captures encounters where patients are non-verbal, delirious, severely aphasic, severely developmentally delayed, or have severe sensory impairments, and thus cannot provide the information needed for routine screening or assessment. Nationally, clear reporting of these encounters supports accurate utilization tracking, resource planning, and appropriate documentation of care limitations.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will learn what the code represents clinically and operationally, where it is typically used, and which payers commonly recognize the code. The publication reviews benchmarks and policy context relevant to documenting incomplete assessments, clarifies common service settings, and summarizes payer coverage patterns where available. Data not available in the input includes specific associated taxonomies, ICD-10 diagnoses, related codes, and service-line financial benchmarks. This summary provides a concise reference for clinicians, coding staff, and policy analysts seeking to understand the clinical intent and administrative role of G0037 in national billing practice.
Billing Code Overview
HCPCS Level II code G0037 indicates that on the date of encounter the patient is not able to participate in assessment or screening, including situations such as non-verbal status, delirium, severe aphasia, severe developmental delay, or severe visual or hearing impairment when no knowledgeable informant is available.
Service type: Assessment or screening attempt not feasible due to patient incapacity or lack of informant.
Typical site of service: Outpatient clinics, emergency departments, inpatient hospital wards, skilled nursing facilities, and home health visits where screening or assessment would normally be performed but cannot be completed because the patient cannot participate and no informant is available.
Clinical & Coding Specifications
Clinical Context
A home health nurse visits an elderly patient with advanced dementia who is nonverbal and currently delirious following a recent hospitalization. On the scheduled assessment date the patient is unable to participate in functional and cognitive screening due to severe aphasia and fluctuating consciousness, and no family member or other knowledgeable informant is present or reachable. The nurse documents the inability to perform the standardized assessment, records observed vital signs and behavior, notifies the supervising physician, and bills G0037 to indicate that the assessment/screening could not be completed because the patient could not participate and no knowledgeable informant was available. Typical workflow includes arrival, attempted patient interview and screening, documentation of reasons for inability to assess (e.g., nonverbal, delirium, severe sensory impairment), attempts to contact caregivers, communication with the ordering clinician, and submission of G0037 with appropriate visit and clinical notes supporting the circumstances.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when services required substantially greater work than typical due to complexity of care or documentation complexity associated with inability to assess |
