HCPCS code H0045: Respite care services, not in the home, per diem

Key takeaways

HCPCS code H0045 covers respite care delivered outside the patient’s home, billed as one unit per calendar day.

Medicaid is the primary payer for H0045. Medicare does not cover it as a standalone benefit, and commercial coverage is rare.

Never report H0045 when skilled nursing care runs during the same service period. The code pays for caregiver relief, not clinical treatment.

Most state Medicaid programs require prior authorization before the respite day is delivered, and there is no appeal path without it.

Practice management software like Pabau keeps the plan of care, the authorization record, and the service log in one patient file.

HCPCS code H0045 sits in the HCPCS Level II code set maintained by the Centers for Medicare and Medicaid Services (CMS). Its official descriptor reads: Respite care services, not in the home, per diem. The code covers temporary relief for caregivers of people with behavioral health or developmental needs. That relief is delivered away from the patient’s home, in a group home, residential facility, or adult day program.

The per diem unit means one unit equals one full day of service, whatever the hour count inside that day. Providers submit one unit per calendar day of respite delivered outside the home. H0045 sits in the H0000-H2037 behavioral health services range of HCPCS Level II.

What services does HCPCS code H0045 cover?

H0045 covers temporary out-of-home respite that gives a primary caregiver a break. The recipient is someone with behavioral health, developmental, or intellectual disability needs. The code applies only when that relief happens in a structured setting away from the patient’s residence. Clear care coordination documentation is what proves the service met that definition.

Provider settings that typically qualify under H0045 include:

• Group homes providing temporary residential placement
• Residential treatment facilities offering short-term stays
• Community-based adult day programs with behavioral health capacity
• Crisis respite centers operating outside the home
• Behavioral health respite camps or specialized day programs

The service period is one calendar day. The code does not distinguish between a daytime stay and an overnight stay inside that day. Providers billing consecutive days submit one unit per day.

Document the caregiver relief rationale, not only the recipient’s diagnosis. Payers check whether the day was needed to prevent caregiver burnout, rather than to deliver clinical treatment to the recipient.

Structured relief programs matter clinically, and caregiver burnout rises when they are hard to reach. That context is what supports the medical necessity statement on an H0045 claim.

H0045 fee schedule and reimbursement rates

Reimbursement for H0045 is set entirely at the state Medicaid level. There is no national Medicare rate, because Medicare does not routinely cover the code. Per diem rates vary by state, by Medicaid managed care organization (MCO) contract, and by fiscal year update cycle.

The figures below reflect published state Medicaid fee schedule benchmarks. Always check your state’s current Medicaid billing manual before you submit a claim. The AAPC HCPCS code lookup and state Medicaid portals carry the most current rates.

Important: These are benchmark ranges drawn from published Medicaid fee schedule data, and they move with annual state budget cycles. Commercial coverage for H0045 is rare, since most private insurers leave out-of-home respite out of their standard benefit structures.

Get a coverage verification before you render the service. That matters most under MCO contracts, which may negotiate rates separately from the state plan. You can cross-reference current code status with the PGM Billing HCPCS lookup tool.

Medicare vs. Medicaid coverage for H0045

Medicare does not cover H0045 as a standalone respite benefit outside of hospice. Traditional Medicare does pay for hospice respite under Part A, but that benefit uses different coding and billing rules. Submit H0045 to Medicare fee-for-service and you will usually get a non-covered service denial.

Check Medicare coverage status each year in the CMS HCPCS files, since coverage determinations change. Practices running a mental health EMR should flag H0045 as Medicaid-primary in the billing workflow configuration.

Common modifiers used with H0045

Modifiers tell the payer about the nature of the service, the provider’s qualifications, or the setting. For H0045 the common ones fall into two groups. National behavioral health modifiers come first, then state-specific U-modifiers.

States do not all want the same modifier stack, so confirm yours in the Medicaid billing manual or with the relevant MCO. The NLM Clinical Table HCPCS API gives programmatic access to current modifier data for verification.

Note on U-modifiers: The U1-U9 range is state-defined. A U2 modifier in California means something different from U2 in Ohio. Never carry modifier conventions from one state billing environment into another without checking. The wrong state modifier is a common denial cause, and many Medicaid systems will not let you correct it on the original claim.

Place of service codes for H0045

Place of service (POS) codes tell payers where the service happened. For H0045, the right POS code depends on the facility type where the out-of-home respite took place.

POS 11 (office) and POS 12 (home) both contradict the code’s “not in the home” descriptor, so either one triggers a payer edit. Check POS requirements with your state Medicaid program, because some states restrict H0045 to certain approved setting types.

Documentation requirements for H0045 billing

Documentation deficiencies are the top reason Medicaid auditors recover money on H0045 claims. The burden is twofold. You have to establish that the recipient qualifies for out-of-home respite, and that the caregiver needs relief. Neither element on its own is enough.

Digital intake forms that capture the clinical rationale and the caregiver status at intake reduce the risk of missing one of them at audit. Storing that paperwork to HIPAA compliance standards also keeps it accessible when a reviewer asks.

Required documentation elements for H0045 claims usually include:

• Plan of care: A current, signed plan of care that lists out-of-home respite as an authorized service. Most Medicaid waiver programs want it updated every 12 months.
• Medical necessity justification: A written rationale for why out-of-home respite is needed, naming the recipient’s diagnosis and the caregiver’s relief needs.
• Prior authorization record: The PA number, approval date, authorized units, and the authorizing payer. Most Medicaid programs require PA for H0045.
• Service delivery log: Date of service, start and end times or a per diem notation, staff name and credentials, and the recipient’s Medicaid ID.
• Provider credentials: Proof of the direct service worker’s qualifications, matching any credential modifier submitted on the claim.
• Caregiver relief record: Evidence that the primary caregiver was absent or relieved during the service period, not only that the recipient received care.

A structured caregiver care plan makes the relief element easy to evidence, because it records who normally provides the care and when. The recipient’s diagnosis usually traces back to the intake assessment, and a well-documented psychiatry interview gives the reviewer a clear source.

Capture all of this at the time of service rather than reconstructing it later. Purpose-built medical forms are how practices manage that. Strong documentation compliance habits also protect you from retrospective recovery, which some states pursue up to five years after the date of service.

When not to use H0045

H0045 has a narrow scope and clear exclusions. Billing it outside that definition generates denials, and a pattern of incorrect use can trigger a wider Medicaid audit. These are the common errors:

• Skilled nursing care billed concurrently: H0045 pays for caregiver relief, not skilled clinical services. If the recipient receives skilled nursing care in the same service period, do not report H0045. The two are mutually exclusive for that period.
• In-home services coded as H0045: The descriptor says “not in the home.” Respite delivered inside the recipient’s own home belongs under S5150, S5151, or T1005, depending on the billing unit and the payer.
• Missing prior authorization: Most state Medicaid programs require PA before the service is delivered. Providing the day without an active authorization usually means a denied claim with no appeal path.
• Medicare as primary payer: H0045 sent to Medicare fee-for-service outside hospice comes back as a non-covered denial. Only submit it if you have confirmed a specific Medicare Advantage benefit for out-of-home respite.
• Commercial insurance without verified benefits: Most commercial plans do not cover H0045. Submitting without a benefits check risks delayed payment, balance billing disputes, and patient complaints.

H0045 vs. related respite care codes: S5150, S5151, and T1005

Choosing the wrong respite code produces a denial that needs a payer-level correction rather than a quick resubmission. H0045 is for out-of-home respite billed per diem. The codes below cover in-home or per-hour alternatives.

Picking between them means knowing the service setting and the payer’s preferred billing convention. That is core work for any organization running several waiver programs on one practice management software setup.

Key distinction: H0045 names both the setting and the unit. T1005 names neither, so it can cover respite in any setting, billed in 15-minute increments. Some states use one code, some the other, and some use both for different program types. When a state Medicaid program only accepts T1005 for a waiver, an H0045 claim will deny however accurate the service was. Check the preferred respite code for each waiver program before you configure billing.

H0045 adjacent codes in the H-code range

HCPCS code H0045 sits inside a behavioral health H-code block covering crisis and support services. Knowing the neighbors helps billing staff decide quickly whether a service belongs under H0045 or the code beside it. Screening and eligibility work sits further up the same block, under H0002.

The Medicare Informatics HCPCS tables hold a searchable reference for the full range. For teams billing several behavioral health codes at once, compliance management tools that flag code-level payer rules cut the risk of conflicting service combinations.

How Pabau keeps H0045 documentation and claims aligned

Out-of-home respite documentation usually lives in three places. The plan of care sits in a clinical file, the authorization number in a spreadsheet, and the daily service log on a paper sheet. At audit, someone has to reassemble all three for every claim.

Practice management software like Pabau holds them in one patient record instead. Intake forms capture the caregiver relief rationale, treatment notes carry the service log, and claims management software pulls the authorization details straight onto the claim.

Every entry is timestamped against the record, so the audit trail builds itself while your team works. The same setup covers behavioral health and therapy practice teams running several waiver programs at once, with no second spreadsheet to reconcile.

So you spend less time hunting for paperwork after a recovery letter lands, and fewer claims deny for a missing authorization number.

Keep respite claims audit-ready

Pabau brings the plan of care, the authorization record, and the daily service log into one patient file. Your team bills H0045 from documentation that is already complete.

Conclusion

H0045 is a narrow code, and the discipline it asks for is nearly all front-loaded. Get the authorization and the caregiver relief rationale on file before the respite day happens, and the claim itself becomes routine.

The trade-off worth remembering is that state variation outweighs the code. The same service, documentation, and modifier stack can pay in one state and deny in the next. Treat your state’s billing manual as the authority and this page as the map.
