CPT® Code 96160

Add-On Code

Key Takeaways: 2025 Health Risk Assessments

• Definition: CPT 96160 reports the administration and scoring of a patient-focused health risk assessment (e.g., AUDIT-C, CRAFFT).
• Medicare Rule: Do not bill 96160 separately with an Annual Wellness Visit (AWV), as the Health Risk Assessment is bundled.
• SDOH Update: Use new HCPCS code G0136 for Social Determinants of Health assessments for Medicare patients instead of 96160.
• Frequency: Medicare typically limits reimbursement to 3 units per date of service.

Introduction

CPT code 96160 allows healthcare providers to capture the work involved when patients fill out standardized questionnaires about their health risks. In 2025, the correct use of this code is vital for compliance, especially with the introduction of new Social Determinants of Health (SDOH) codes like G0136. This guide covers the official definition, eligible providers, documentation needs, and payer-specific billing rules.

Official CPT Definition of 96160

The AMA defines CPT 96160 as the "administration of patient-focused health risk assessment instrument (e.g., health hazard appraisal) with scoring and documentation, per standardized instrument."

This covers giving the patient a standardized tool, scoring it, and documenting the results. It is distinct from 96161, which is used for caregiver-focused assessments (e.g., postpartum depression screen for a mother during a child's visit).

Clinical Scenarios and Settings for Use

• Primary Care: Used for general health hazard appraisals or lifestyle questionnaires during wellness exams (for non-Medicare payers).
• Behavioral Health: Screening for substance use (e.g., AUDIT, CRAFFT) or psychosocial risks. Note: Use 96127 for brief behavioral assessments like PHQ-9 for depression.
• Chronic Disease: Assessments for transition readiness (pediatric to adult care) or specific disease management questionnaires.

Who Can Administer and Report 96160

The code reflects practice expense (staff time/supplies), meaning clinical staff (MA, nurse) can administer and score the tool. The billing provider (MD, DO, NP, PA) must review the results and document any intervention. The review/counseling is part of the E/M service, while 96160 captures the administration.

Documentation Requirements

To support billing, your medical record must include:

• Name of Instrument: (e.g., "AUDIT-C Alcohol Screen").
• Score/Result: (e.g., "Score: 4, Moderate Risk").
• Date: Date of administration.
• Review: Provider note stating results were reviewed and discussed (e.g., "Dr. Smith reviewed HRA results; counseling provided on alcohol reduction").

Medicare (CMS):

• AWV Restriction: Do not bill 96160 with an Annual Wellness Visit (G0438/G0439). The HRA is bundled into the AWV payment.
• Specific G-Codes: Use specific screening codes like G0444 (Depression) or G0442 (Alcohol) when eligible, rather than 96160.
• SDOH Update: For social risk screenings, use G0136 (see 2025 Updates section).
• Stand-Alone Services: Medicare generally considers 96160 a non-covered service if done as a stand-alone preventive screening without a related visit.

Commercial Payers: Many commercial plans reimburse 96160 separately, often incentivizing screenings. Check policies for frequency limits or specific diagnosis requirements (e.g., Z13.9 for screening).

96160 with Preventive Services (AWV and Others)

Warning: Medicare denies 96160 billed on the same day as an Annual Wellness Visit (G0438/G0439). The Health Risk Assessment is a mandatory, bundled component of the AWV.

For commercial physicals (99395, etc.), 96160 is often payable. Attach modifier 33 if the payer considers it a preventive service under ACA rules to waive cost-sharing.

Modifiers, Units, and Payer Edits

• Multiple Units: Report 96160 once per distinct instrument. Medicare has an MUE (Medically Unlikely Edit) limit of 3 units per day.
• Modifier 59/XU: Use if NCCI edits bundle 96160 with another code (e.g., 96127) performed on the same day, to indicate a separate, distinct assessment.
• Modifier 25: Generally not required on the E/M code for 96160, as it is not a "procedure" with global days. Use only if a specific payer requires it.
• Place of Service Denials: Be aware that some payers (e.g., Railroad Medicare) have denied 96160 when billed with a Home Visit place of service.

Common Denial Reasons and Compliance Tips

• Bundled Service: Denied because it was billed with a Medicare AWV. Fix: Do not bill separately.
• Diagnosis Mismatch: Denied for lack of medical necessity. Fix: Use appropriate screening Z-codes (e.g., Z13.89).
• Invalid Tool: Using a non-standardized form. Fix: Use validated tools (CRAFFT, PHQ, etc.).

2025 Updates and Changes

• SDOH Code G0136: Medicare introduced G0136 for administering a standardized Social Determinants of Health risk assessment (5-15 mins). Use this instead of 96160 for SDOH screenings on Medicare patients.
• Increased Reimbursement: Some Medicaid programs (e.g., WA) have increased rates for 96160 to encourage behavioral/social screenings.
