HCPCS code H0024 – Behavioral health prevention information dissemination

Key takeaways

HCPCS code H0024 covers behavioral health prevention information dissemination, not treatment or counseling.

H0024 is a Medicaid code. Medicare does not recognize or pay for it, so coverage, units, and rates come from each state plan.

Documentation must record the service date, type of prevention activity, number of individuals reached, and staff qualifications.

Pabau, the practice management platform we build, keeps H0024 session logs, forms, and invoices together, so each claim has its supporting record.

HCPCS Code H0024: Definition and official 2026 descriptor

HCPCS Code H0024 is the Healthcare Common Procedure Coding System Level II code for behavioral health prevention information dissemination service.

It belongs to the H-series (H0001-H2037), which state Medicaid agencies use for drug, alcohol, and behavioral health services. Because H codes are state Medicaid codes, Medicare does not recognize or pay for them.

Reimbursement rates for HCPCS Code H0024 are set by each state Medicaid plan independently, and there is no single national rate. Before billing, check your state’s published Medicaid fee schedule, because each state updates its amounts on its own cycle. Neighboring H codes, from assessment to case management, are listed in our HCPCS codes reference.

What services does H0024 cover?

H0024 covers structured prevention activities whose purpose is informational. They share knowledge about behavioral health risks, substance use consequences, and protective factors with people who have not entered a formal treatment program. The key clinical distinction is that the service informs rather than treats.

Qualifying activities fall into these categories:

• In-person group presentations delivered to community participants, students, or workplace populations on alcohol, drug, and behavioral health prevention topics
• Individual information sessions providing prevention content without clinical assessment or therapeutic intervention
• Print and digital distribution of evidence-based prevention materials (brochures, toolkits, structured e-modules) when delivered with provider oversight as part of a session
• Community outreach sessions conducted by certified prevention specialists or qualified behavioral health staff in community settings, schools, or faith-based organizations
• Structured curriculum delivery using evidence-based prevention programs such as LifeSkills Training or Too Good for Drugs, with the unit defined by your state plan

Some programs funded by the Substance Abuse and Mental Health Services Administration (SAMHSA) deliver sessions that fit this description. Whether those sessions can be billed as H0024 depends on your state Medicaid plan’s coverage rules.

What H0024 does not cover: Exclusions and limitations

Billing H0024 for a service that belongs to an adjacent code exposes the claim to denial and the program to repayment. These activities fall outside H0024’s scope:

• Substance use disorder treatment — billed with codes such as H0001 (alcohol and/or drug assessment) or H0004 (behavioral health counseling and therapy, per 15 minutes)
• Individual counseling or therapy — even when alcohol or drug prevention is the topic, a therapeutic interaction with clinical goals is not a prevention information session
• Case management services — billed with H0006 (alcohol and/or drug services; case management) or the case management codes your state specifies
• Hotline and crisis calls — a hotline service is billed with H0030, and crisis intervention with the codes your state specifies
• Assessment and evaluation — billed with H0001 or diagnostic evaluation codes
• Medication-assisted treatment (MAT) counseling — not a prevention information service, whatever the setting

A useful internal test is to picture the record the session would produce. A clinical note with treatment goals, a progress update, or a diagnostic impression means it is not an H0024 session. An H0024 session produces an outreach service log, which records who attended, what was covered, and who delivered it.

H0024 vs H0025 and adjacent H-codes: How to tell them apart

H0024 is most often confused with H0025 (behavioral health prevention education service) and H0026 (alcohol and/or drug prevention process service, community-based). All three are prevention codes. The difference lies in how the service reaches people and what it aims to change.

The clearest decision rule follows the descriptors. Use H0024 when the session is one-way contact that informs an audience, such as a presentation or an information session. Use H0025 when the service works with a target population to change knowledge, attitude, or behavior. Use H0026 when the work builds the skills of impactors in a community-based process.

Always check your state’s Medicaid provider manual, because each state sets its own coverage rules for these codes. The decision path below sets the three prevention codes against the treatment codes they are most often confused with.

Eligible provider types and qualifications for HCPCS Code H0024

Eligible provider types for HCPCS Code H0024 vary by state Medicaid plan, and no federal rule designates a single universal provider type. The following categories are commonly recognized across state plans, subject to state-level credentialing and supervision requirements:

• Certified Prevention Specialists (CPS) and Certified Prevention and Recovery Specialists credentialed under state or NAADAC standards
• Licensed Clinical Social Workers (LCSW) and Licensed Professional Counselors (LPC) providing prevention outreach within their scope
• Community Health Workers (CHW) when working under a licensed supervising provider and the state plan permits CHW billing
• Certified Community Behavioral Health Clinics (CCBHCs), which may bill H0024 depending on the state plan
• Substance use disorder agencies and prevention organizations enrolled as Medicaid providers in their state

Provider eligibility is governed by your state Medicaid agency’s provider enrollment rules, not by CMS directly. Before billing H0024, confirm that your provider type is listed as eligible in your state’s Medicaid behavioral health provider manual. A claim billed under a provider type your state plan does not recognize is denied, and no modifier can fix it.

How to bill H0024: Modifiers, units, and place of service

Billing HCPCS Code H0024 correctly means getting four things right at once: modifier selection, unit count, place of service code, and claim form fields. A mistake on any one of these commonly results in a denial rather than a request for additional information.

Modifiers

Modifier applicability for H0024 is state-determined. The following modifiers are used on H0024 claims in various state Medicaid plans, but verify each with your state’s billing manual before applying it:

Units and place of service

CMS does not define a billing unit for H0024, so the unit comes from your state Medicaid plan. Check whether your state counts a unit per session or per block of time before you enter the unit count. Never bill multiple units for a single session unless your state’s billing manual explicitly allows it for H0024.

Common Place of Service (POS) codes used with H0024:

• POS 11 (Office) for sessions delivered at a provider’s licensed facility
• POS 49 (Independent clinic) for freestanding clinics, or POS 50 (Federally Qualified Health Center) for FQHC-based programs
• POS 53 (Community mental health center) for CMHC-delivered prevention services
• POS 99 (Other place of service) for community outreach settings when no more specific POS applies

On CMS-1500 claims, H0024 and its modifiers go in Box 24D. On UB-04 facility claims, use the revenue code your state’s institutional billing manual specifies for prevention services. Keeping session logs and claims in one system, such as claims management software, helps here. The code, modifier, and POS on each claim can then be checked against the record.

Medicaid billing rules and prior authorization for H0024

H0024 Medicaid billing operates entirely within state Medicaid plans. CMS does not set a national coverage determination for H0024. Each state Medicaid agency decides whether to cover the code, at what rate, and under what prior authorization conditions.

Key Medicaid billing rules that apply in most states covering H0024:

• Provider enrollment is a prerequisite. The billing provider must be enrolled as a Medicaid behavioral health or prevention services provider in the state. Claims submitted under an unenrolled or mis-enrolled NPI are rejected before they reach clinical review.
• Prior authorization requirements vary. Some state plans require PA for H0024 when services exceed a set number of sessions per beneficiary per period. Others cover a set number of sessions without PA. Check the PA requirements for your state Medicaid plan before the service occurs.
• Beneficiary eligibility must be verified. Medicaid eligibility can change between the verification date and the service date. Verifying eligibility on or as close to the service date as possible reduces eligibility-based denials.
• Claims must be submitted within the state’s timely filing window. Most state Medicaid plans require claims within 90-365 days of service, depending on the plan. Late submissions are denied and generally cannot be appealed on merit.

Understanding medical billing workflows for Medicaid-specific codes like H0024 matters most for prevention programs that also receive SAMHSA funding. Dual funding needs careful claim tracking, so Medicaid is never billed for a service a SAMHSA grant already paid for.

Documentation requirements for H0024 claims

Documentation requirements for H0024 come partly from federal rules, such as HIPAA and SAMHSA program standards, and largely from state Medicaid policy. The elements below are the baseline found across state plans that cover H0024. Verify any additional requirements with your state Medicaid agency.W

H0024 documentation is an outreach activity log, so keep treatment goals, diagnostic impressions, and progress narratives out of it. Clinical language can lead auditors to reclassify the service as a treatment encounter. That may require a different code and could result in a demand for repayment. Behavioral health billing compliance requirements for Medicaid prevention codes treat outreach records and clinical records differently.

Common reasons H0024 claims are denied and how to fix them

Community-based prevention programs often run with small billing teams whose expertise lies in prevention science rather than Medicaid rules. The table below maps each denial category that applies to H0024 to its root cause and fix. Effective denial mWnagement strategies for H0024 start with knowing these categories.

H0024 in practice: Workflow and billing checklist

A clean H0024 claim starts before the session is delivered. The workflow below builds documentation and billing steps into service delivery, which cuts rework at claim submission. Effective revenue cycle management for prevention programs depends on that end-to-end process as much as on accurate coding.

1. Before the session: Verify beneficiary Medicaid eligibility for the service date. Confirm H0024 is covered in your state plan. Obtain prior authorization if your state requires it. Identify the correct modifier for the delivery format (individual vs group; staff credential level).
2. During the session: Record start and end times. Document the curriculum or topic delivered, the setting, and the staff member’s name and credentials. For group sessions, record the participant headcount.
3. After the session: Complete the service activity log within 24 hours while details are current. Have the supervising clinician sign off if your state plan requires it. Do not add clinical assessment language to the record.
4. At claim preparation: Enter H0024 in Box 24D. Apply the correct modifier. Match the POS code to the actual delivery setting. Calculate units using your state plan’s unit definition, since CMS does not define one for H0024.
5. Before submission: Run a pre-submission check against your state plan’s required documentation elements. Confirm the claim is within the timely filing window. Verify that the rendering provider NPI on the claim matches the enrolled NPI.

Pre-submission checklist for H0024 claims:

• Medicaid eligibility verified on or near the service date
• Prior authorization on file (if required by state plan)
• Service activity log complete with all required elements
• Correct modifier applied and verified against state billing manual
• POS code matches actual delivery setting
• Units match your state plan’s unit definition
• Rendering provider NPI matches enrolled provider
• Claim submitted within timely filing window

How Pabau keeps H0024 session records claim-ready

Many prevention programs keep attendance sheets on paper, staff credentials in a spreadsheet, and invoices in a separate billing tool. When a state Medicaid reviewer asks for the record behind an H0024 claim, someone has to assemble it from three places.

Pabau, the practice management platform we build, brings those pieces into one system. You can set up the session log as a digital form with the fields your state requires, such as headcount, topic, setting, and staff credentials. Payments and invoicing sit in the same platform, so the invoice and its supporting log stay together.

The outcome is a log completed at the point of service. Your quarterly audit then runs from Pabau’s reporting instead of a search through folders.

Keep H0024 session records audit-ready

Pabau brings digital forms, records, invoicing, and reporting into one platform. Each prevention session log is ready when a Medicaid reviewer asks for it.

Conclusion

H0024 rewards programs that settle the code before the session rather than after a denial. If the session informs an audience and stops there, it is H0024. If it works with participants to change behavior or builds the skills of impactors, look at H0025 or H0026. If it treats, it needs a treatment code.

The practical step this week is to pull your state Medicaid provider manual and answer three questions. Does it cover H0024, how does it define a unit, and which modifiers does it accept? A session log built around those answers holds up in an audit.

The trade-off is a few minutes of logging per session, against the risk of losing every claim from a session that went unrecorded. Book a demo to see how Pabau keeps prevention session logs, forms, and invoices together for Medicaid review.
