Pediatric Disaster Behavioral Health (PDBH) Toolbox

Reference list for institutional revenue capture on pediatric disaster behavioral health services. Codes verified against 2025–2026 Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS) guidance. State Medicaid, commercial, and payer-specific rules vary; verify locally before implementation.

Disaster-Specific Modifiers and Codes

These are the codes that flag claims as disaster or emergency-related and unlock the billing flexibilities tied to 1135 waivers. They are the most relevant codes in this reference for disaster contexts and should be incorporated into every relevant claim during a declared event.

• Modifier CR (Catastrophe/Disaster Related): Applied to Part B items and services (both institutional and non-institutional billing) when a service is affected by a declared disaster or public health emergency. Use is mandatory for applicable HCPCS codes when Medicare payment is conditioned on an 1135 waiver.
• Condition Code DR (Disaster Related): Applied at the claim level on institutional billing when all services on the claim are related to the disaster or emergency. Mandatory when payment is conditioned on an 1135 waiver.

Operational note: Use of CR and DR is contingent on a Presidential declaration under the National Emergencies Act or Stafford Act, an HHS public health emergency declaration under PHS Act §319, and the Secretary's election to waive Title XVIII requirements under §1135. Specific guidance on geographic scope, start/end dates, and applicable waivers is issued by CMS for each declared event.

Encounter Codes (ED, Inpatient, Outpatient)

Most pediatric disaster behavioral health care is billed under standard E/M encounter codes, with PBH-specific procedure codes layered on as appropriate. The encounter codes below are commonly underutilized in revenue capture.

Emergency Department

• 99281–99285: Emergency department E/M services, levels 1–5. Most pediatric BH presentations in the ED are billed under these.

Inpatient and Observation

• 99221–99223: Initial hospital inpatient or observation care, levels 1–3.
• 99231–99233: Subsequent hospital inpatient or observation care, levels 1–3. Relevant during BH boarding.
• 99238: Hospital inpatient or observation discharge management, 30 minutes or less.
• 99239: Hospital inpatient or observation discharge management, more than 30 minutes.
• 99291: Critical care, first 30–74 minutes. May be appropriate in severe agitation management that requires critical care services, post-overdose, or unstable post-exposure scenarios.
• 99292: Critical care, each additional 30 minutes.

Office and Outpatient

• 99202–99205: New patient office or outpatient E/M, levels 2–5.
• 99211–99215: Established patient office or outpatient E/M, levels 1–5.

Prolonged Services Add-On

• 99417: Prolonged outpatient E/M services, each additional 15 minutes beyond the highest-level base code. Replaced the older 99354/99355 pair for outpatient services

Psychiatric Diagnostic and Evaluation

• 90791: Psychiatric diagnostic evaluation, without medical services. Used by non-prescribing clinicians (psychologists, social workers, counselors, and family therapists).
• 90792: Psychiatric diagnostic evaluation with medical services. Used by physicians, psychiatric NPs, PAs

Psychotherapy (Individual)

• 90832: Psychotherapy, 30 minutes with patient (16–37 minutes).
• 90834: Psychotherapy, 45 minutes with patient (38–52 minutes).
• 90837: Psychotherapy, 60 minutes with patient (53+ minutes).
• 90785: Interactive complexity add-on. Reported in conjunction with 90791, 90792, 90832, 90834, 90837, or 90853 when communication factors increase complexity (e.g., caregiver/third-party involvement, language or cultural barriers, mandated reporting requirements, disclosure of traumatic content, or difficulty managing maladaptive communication).

Crisis Psychotherapy

• 90839: Psychotherapy for crisis, first 60 minutes (per CPT descriptor).
• 90840: Psychotherapy for crisis, each additional 30 minutes (add-on to 90839).

Operational thresholds: Despite the "first 60 minutes" descriptor, the actual billing rule is: 90839 covers 30–74 minutes of crisis psychotherapy; 90840 is added once total time exceeds 74 minutes, with one unit per additional 30 minutes. Sessions under 30 minutes should be billed as standard psychotherapy (90832). 90839 cannot be reported with 90785–90899 on the same day. Only face-to-face time counts; documentation, coordination, and phone calls are billed separately.

Family and Group Interventions

• 90846: Family psychotherapy without the patient present, 50 minutes.
• 90847: Family psychotherapy with the patient present, 50 minutes.
• 90849: Multiple-family group psychotherapy.
• 90853: Group psychotherapy (other than multiple family).

Health Behavior Assessment and Intervention

These codes are appropriate for children whose primary diagnosis is a physical health condition with disaster-related psychological, behavioral, emotional, cognitive, or social factors complicating recovery (e.g., a child injured in a tornado dealing with adjustment, a child with chronic medical illness whose care is disrupted by displacement.) They are billable by clinical psychologists, clinical social workers, family therapists, and mental health counselors.

• 96156: Health behavior assessment or re-assessment. No time threshold; reported once per assessment.
• 96158: Health behavior intervention, individual, face-to-face, initial 30 minutes.
• 96159: Health behavior intervention, individual, each additional 15 minutes (add-on to 96158).
• 96164: Health behavior intervention, group, initial 30 minutes.
• 96165: Health behavior intervention, group, each additional 15 minutes (add-on to 96164).
• 96167: Health behavior intervention, family with patient present, initial 30 minutes.
• 96168: Health behavior intervention, family with patient present, each additional 15 minutes (add-on to 96167).
• 96170: Health behavior intervention, family without patient present, initial 30 minutes.
• 96171: Health behavior intervention, family without patient present, each additional 15 minutes (add-on to 96170).

Important caveat: These codes are not reported on the same day as psychiatric services (90785–90899) for the same patient. Use psychiatric codes when the primary diagnosis is a mental health disorder; use health behavior codes when the primary diagnosis is a physical health condition with behavioral or psychological factors.

Screening, Testing, and Assessment

• 96127: Brief emotional/behavioral assessment with scoring and documentation, per standardized instrument (e.g., PHQ-9, PSC-17, GAD-7, PC-PTSD-5, SCARED, CRAFFT). Low-effort, high-volume billable service well-suited to embedding in ED triage and follow-up workflows after a disaster.
• 96130–96133: Psychological testing evaluation services (clinician work).
• 96136–96139: Psychological/neuropsychological test administration and scoring.

Crisis and Community-Based Services (HCPCS)

HCPCS Level II codes used primarily by state Medicaid programs and commercial behavioral health carve-outs. Coverage and definitions vary by state and payer. Coverage caveat: S-codes are not recognized by Medicare; H-codes vary substantially in scope, definition, and reimbursement across state Medicaid programs. Verify coverage with each payer before relying on these codes in surge planning.

• H2011: Crisis intervention service, per 15 minutes.
• H2019: Therapeutic behavioral services, per 15 minutes.
• S9484: Crisis intervention, per hour (community or facility based).
• S9485: Crisis intervention, per diem

Care Coordination and Integration

General Behavioral Health Integration

• 99484: Care management services for behavioral health conditions, 20 minutes per calendar month by clinical staff under physician/qualified health professional supervision.

Federally Qualified Health Center Care Management

• G0511: FQHC/RHC general care management (chronic care, behavioral health integration, principal care management).
• G0512: FQHC/RHC psychiatric collaborative care management.

Transitional Care Management

• 99495: Transitional care management, moderate complexity, communication within 2 business days of discharge, face-to-face visit within 14 days.
• 99496: Transitional care management, high complexity, communication within 2 business days of discharge, face-to-face visit within 7 days. Often appropriate post-BH boarding or post-inpatient psychiatric discharge.

Telehealth: Modifiers, Place of Service, and Digital Services

Telehealth claims require both a service modifier and an appropriate Place of Service (POS) code. Omitting POS is a common cause of denials.

Modifiers

• 95: Synchronous telemedicine service rendered via real-time interactive audio and video.
• 93: Synchronous telemedicine service rendered via audio-only telecommunications, when video is unavailable or declined by the patient. Required by Medicare and many payers; documentation must support why audio-only was used.
• FQ: Audio-only telehealth provided by an FQHC or RHC. Identical in meaning to 93 but reserved for federally qualified health centers and rural health clinics.

Place of Service

• POS 02: Telehealth provided to a patient who is not in their home.
• POS 10: Telehealth provided to a patient who is in their home.

Digital Communication Services

• 98016: Brief communication technology-based service ("virtual check-in"), 5–10 minutes.
• 99421–99423: Online digital evaluation and management (e-visit) by a physician or other qualified health care professional, cumulative time over 7 days (5–10, 11–20, 21+ minutes).
• 98970–98972: Online digital assessment and management by a non-physician qualified health care professional, cumulative time over 7 days (5–10, 11–20, 21+ minutes).
