CPT Code 96156: Health Behavior Assessment or Re-Assessment

What is CPT 96156?

CPT 96156 is a health behavior assessment or re-assessment: a health-focused clinical interview, behavioral observations, and clinical decision making about psychological, behavioral, or social factors affecting a physical health problem, such as diabetes or chronic pain. It is not time-based. Follow-up intervention sessions use 96158 and related codes.

Assessment of the psychological, behavioral, emotional, cognitive, and social factors that affect the prevention, treatment, or management of a physical health problem. The focus is the physical condition, not a primary mental health diagnosis.

Time Requirements

Not time-based in CPT. It is reported once per assessment, though payers may limit how often it is billed.

Modifiers

When to Use

  • Assessing psychological or behavioral factors that affect management of a physical health condition
  • Evaluating adherence, coping, or health behaviors that interfere with medical treatment
  • Re-assessment when the health condition or the treatment plan changes

When Not to Use

  • When the primary concern is a mental health diagnosis: use 90791 and psychotherapy codes
  • On the same date as psychiatric service codes (90785 to 90899) or adaptive behavior codes (97151 to 97158); CPT directs you to report the predominant service
  • With an E/M service (including 99401 to 99412) by the same provider on the same date
  • For intervention sessions after the assessment: use 96158 and related intervention codes

What to Document for CPT 96156

  • The physical health condition and the referral question
  • The health-focused interview and behavioral observations
  • Psychological, behavioral, and social factors affecting the condition
  • Recommendations and plan, including any intervention sessions

Common Denial Reasons

  • Primary diagnosis is a mental health condition rather than a physical health condition
  • Billed on the same date as psychiatric or adaptive behavior services
  • Clinician type not covered by the payer for health behavior codes
  • No clear link between the assessment and the physical health condition

Payer Notes

Coverage and eligible clinician types vary by payer. The claim generally lists the physical health condition as the primary diagnosis. Check whether the payer covers health behavior assessment and intervention for your license type.
