Hospice Billing Codes: Practical Guidance for Steadier Revenue

Hospice leaders feel the revenue impact of billing errors faster than almost any other setting. One missed modifier or wrong revenue code on a hospice claim can turn a predictable per diem into weeks of rework, phone calls, and uncertainty in cash flow. When that happens across dozens of patients, you see it in Days in AR, your line of credit, and ultimately your capacity to staff appropriately.

Hospice billing codes are not just a technical detail. They are the language that connects your clinical work to Medicare’s per diem payment system. Understanding how those codes fit together is one of the clearest ways to protect revenue without compromising care.

In this article, we walk through the core hospice billing codes, how they interact with current Medicare payment rules, and where we most often see avoidable mistakes that show up later as denials and recoupments.

How Hospice Billing Fits Into Medicare’s Payment Systems

Across healthcare, Medicare has moved steadily toward prospective payment systems that pay a fixed amount per stay, visit, or day rather than reimbursing every line item. That is true for hospitals under IPPS, skilled nursing facilities under PDPM, and home health agencies under PDGM. Hospice fits the same philosophy but uses a daily per diem structure instead of case-based groupers.

Under the Medicare hospice benefit, your agency receives a fixed per diem for each day a beneficiary is enrolled in hospice under a valid hospice election. The per diem is not adjusted for each nursing visit, aide hour, or supply, as it would be under fee-for-service. Instead, the daily rate is tied to one of four levels of care. CMS updates those daily rates annually in the hospice wage index and payment rate final rule, including an aggregate cap and wage index adjustments that are similar in spirit to other PPS environments.

For fiscal year 2025 CMS finalized a 2.9 percent net increase in hospice payments and raised the national aggregate cap to 34,465.34 dollars, effective October 1, 2024, through September 30, 2025 (GAO summary of FY 2025 hospice rule; AHA overview). For fiscal year 2026 CMS finalized a further 2.6 percent payment update and set the cap at 35,361.44 dollars (CMS FY 2026 hospice fact sheet).

Those annual changes matter, but for day to day billing the bigger question is much simpler: did you assign the correct level of care and the correct codes for the services actually provided on each day of the billing period. It is also essential to accurately record all relevant service-related dates, such as admission, discharge, certification, and death dates, to ensure compliance and proper reimbursement.

Determining Hospice Eligibility

Determining hospice eligibility is a critical first step for hospice agencies, providers, and families seeking to ensure that patients receive appropriate end-of-life care and support. To qualify for the hospice benefit under Medicare Part A, a patient must have a terminal illness with a life expectancy of six months or less, as certified by both the attending physician and the hospice medical director. This certification is not a one-time event—timely recertification is required to maintain eligibility throughout the course of hospice care.

The hospice provider is responsible for thoroughly documenting the patient’s terminal illness and any related conditions in the medical record. This documentation supports the medical necessity of hospice services and is essential for meeting Medicare’s reporting requirements when submitting claims. The hospice program encompasses a comprehensive range of services, including nursing care, medical social services, pain control, and symptom management, all coordinated by an interdisciplinary team of healthcare professionals such as physicians, nurses, and nurse practitioners. The primary caregiver—often a family member—plays a vital role in supporting the patient, and the hospice team provides ongoing guidance and support to both the patient and their family.

Hospice care can be delivered in a variety of settings, including the patient’s home, a nursing facility, or an inpatient hospice facility, depending on the patient’s needs. The type of care provided—whether routine home care, continuous home care, or general inpatient care—is determined by the patient’s clinical situation and is billed using the appropriate revenue codes and HCPCS codes. Accurate coding and timely claim submission are essential for compliance and reimbursement.

The Four Levels of Hospice Care and Their Core Codes

Medicare pays hospice agencies at four distinct levels of care. These levels are designed to address the varying needs of hospice patients throughout their end-of-life journey. Every hospice billing period is built around these categories, and most of your claim lines will reflect the appropriate revenue code and HCPCS for the level of care.

CMS describes these levels as routine home care, continuous home care, inpatient respite care, and general inpatient care. Each level is paid at a national per diem (or hourly equivalent) that is then wage adjusted for your locality and updated each fiscal year (CMS MLN hospice payment overview; recent rate examples).

Routine Home Care (RHC)

Routine home care is the most common level of hospice care. It applies when the patient is at home, in an assisted living facility, or in a nursing facility, and symptoms are managed without a continuous skilled presence.

Under Medicare, routine home care is paid on a two-tier per diem structure. For fiscal year 2025 the national base daily rate is approximately 224.62 dollars for days 1 through 60 and 176.92 dollars for day 61 and beyond, before wage index adjustments. A similar two-tier structure continues in fiscal year 2026, with rates increased by the 2.6 percent update factor (LegalClarity hospice rate summary; Forvis Mazars commentary on 2026 rates).

In the UB-04 claim format, routine home care days are reported with:

Revenue code 0651 for routine home care.
The appropriate HCPCS or accommodation code for RHC as defined in CMS and MAC guidance.

From a billing perspective, the two-tier structure creates a practical documentation and coding risk. You must keep the hospice benefit period dates accurate and track which days fall in the 1–60 window versus the 61+ window. Errors here do not just create denials; they can also drive overpayments that later become recoupments.

Continuous Home Care (CHC)

Continuous home care is intended for short-term crises in the home when a patient has acute symptom management needs that cannot be handled with intermittent visits. It requires at least eight hours of care in a 24-hour period, with more than half of that time provided by nursing staff.

Medicare pays continuous home care on an hourly basis, but operationally it functions as a daily rate multiplied by hours of qualifying care. For fiscal year 2025 the approximate national hourly rate is 67.44 dollars, with a full 24-hour day equivalent of about 1,618.59 dollars before wage adjustments (LegalClarity rate discussion).

Typical coding for continuous home care includes:

Revenue code 0652 for continuous home care.
HCPCS reflecting the continuous home care level.

The compliance risk with CHC is straightforward. Documentation must support the total hours provided in the calendar day, the disciplines involved, and the clinical rationale for continuous care. Billing CHC based on intent rather than the documented hours is a frequent source of denials and post-payment review findings.

Inpatient Respite Care (IRC)

Inpatient respite care is designed to provide short-term relief for family or informal caregivers. The patient is admitted to a contracted facility or hospice inpatient unit for up to five days at a time, and hospice remains responsible for coordination and services.

Respite days are:

Paid at a daily per diem specific to inpatient respite care, updated annually by CMS.
Capped by regulation so that inpatient days cannot exceed 20 percent of your total hospice days across the year (CMS hospice payment systems overview).

On the claim, inpatient respite care is generally reported with revenue code 0655. Errors here often involve confusing respite with general inpatient care when symptoms are more complex than originally expected, or failing to track the five-day respite limit and the 20 percent aggregate inpatient cap.

General Inpatient Care (GIP)

General inpatient care applies when the patient requires short-term, intensive symptom management that cannot be delivered in any other setting. The patient is typically in a hospital, skilled nursing facility, or hospice inpatient unit under a contractual arrangement.

GIP days:

Are paid at the highest of the four hospice per diem rates and updated annually.
Count against the same 20 percent inpatient day cap as respite care.

The corresponding revenue code is typically 0656 for general inpatient hospice care.

The oversight risk with GIP is twofold. First, the clinical record must support why symptoms could not be controlled at the routine home care level. Second, you must monitor length of stay in GIP to avoid unnecessary days at the higher per diem where symptoms have stabilized.

Core Hospice Billing Codes Beyond the Level of Care

While the four revenue codes for levels of care are central, hospice billing for Medicare involves several other critical code sets and data elements that must align for claims to pay correctly. Claims must accurately reflect the services provided to hospice patients, ensuring that all services billed correspond to the actual care delivered. Proper coding is essential to distinguish between treatments related and unrelated to the patient’s terminal illness, as billing rules and modifiers (such as ‘GV’ and ‘GW’) are used to indicate the relationship of services to hospice care.

ICD-10 Diagnosis Coding for Hospice

Hospice claims require accurate ICD-10 coding for the principal hospice diagnosis and all related and unrelated conditions. CMS expects the principal diagnosis to reflect the patient’s terminal illness—the underlying condition that most contributes to the terminal prognosis—not merely a symptom such as debility or adult failure to thrive.

Errors here do not always create instant denials, but they do create risk in the audit environment and can drive probe and educate reviews from Medicare Administrative Contractors. Inconsistent diagnosis coding between the hospice claim and the clinical record is a signal to auditors that documentation and coding processes are not aligned.

From a revenue cycle perspective, the key operational questions are:

Are diagnoses on the UB-04 updated when recertifications reflect significant changes in the terminal condition. Is there a process to validate that the principal diagnosis is supported by the physician’s certification of terminal illness and the plan of care. Do intake and coding teams communicate when referrals list acute hospital discharge codes that do not reflect the longer hospice trajectory.

Hospice diagnoses do not change the per diem rate in the way that case-mix adjusters do under PDPM or PDGM, but they are central to medical necessity and compliance.

HCPCS and Modifiers for Ancillary Hospice Services

Although hospice per diem payments cover most services related to the terminal illness, there are circumstances where specific HCPCS codes and modifiers come into play.

Common examples include:

Attending physician services when the hospice medical director or a patient’s attending physician bills Medicare Part B. Attending physician services may be provided by a doctor, nurse practitioner, or physician assistant. The patient’s attending physician can be an employee or contractor of the hospice, depending on the circumstances. It is important to determine whether the attending physician’s services are related to the hospice patient’s terminal condition, as this affects the use of billing modifiers (GV and GW) and the appropriate billing procedures.

Certain durable medical equipment, prosthetics, orthotics, and supplies that may be billed outside the hospice benefit in limited circumstances.

• Palliative chemotherapy or radiation when provided under arrangements.

When billing for services unrelated to the hospice patient’s terminal condition, condition codes (such as code 07) must be used on claims to indicate that the service is unrelated to the terminal illness. Occurrence codes are also required in claims processing to document key events such as admission, certification, cancellation, termination, and death. Proper use of these codes ensures accurate claims processing and compliance with Medicare requirements.

For hospice billing staff, the priority is not memorizing every HCPCS code but making sure there is a clean workflow so that Part A hospice claims, Part B professional services, and DME vendors are coordinated. Uncoordinated billing is a common source of overlapping claims and subsequent recoupment activity.

Notice of Election (NOE), Notices of Change, and Sequential Billing

Hospice billing codes do not sit in isolation. They exist inside a framework of election, certification, and period-of-care rules.

An initial Notice of Election must be submitted within the required timeframe to establish the hospice benefit period and trigger payment. Late or rejected NOEs lead directly to noncovered days and permanent revenue loss that cannot be corrected with simple claim resubmission. Subsequent Notices of Change adjust key information such as diagnosis, attending physician, or site of care.

Sequential billing rules require that claims be submitted in order and cover continuous spans of days within each benefit period. It is essential to submit claims in the correct sequence to avoid denials and ensure timely reimbursement. Skipped days, overlapping spans, or out-of-sequence billing are frequent denial triggers. When you multiply that by the tiered per diem for routine home care and the inpatient day caps, it becomes clear why hospice billing benefits from a disciplined workflow rather than ad hoc clean up.

How Payment Updates and Caps Affect Coding Strategy

Because hospice is part of the broader Medicare PPS landscape, payment updates and policy changes at CMS filter into daily billing work in concrete ways.

The FY 2025 and FY 2026 hospice rules continue a pattern of modest annual per diem updates, typically in the 2 to 3 percent range, tied to the inpatient hospital market basket with a productivity adjustment (GAO FY 2025 hospice rule report; CMS FY 2026 hospice fact sheet). At the same time, CMS has placed a permanent 5 percent cap on any year-over-year decrease in the wage index for a geographic area and continues to apply an aggregate cap on total hospice payments per patient per year (MLN hospice payment systems overview).

For hospice agencies, this environment creates three practical billing imperatives.

First, you cannot count on rate increases to compensate for preventable denials or underpayments. Accurate revenue code assignment, clean NOEs, and correct benefit period tracking are still the most direct way to stabilize cash flow.

Second, you must monitor inpatient days across general inpatient and respite care, because exceeding the 20 percent inpatient cap can trigger repayment obligations even when every individual claim line was coded correctly.

Third, you need to align billing workflows with emerging quality reporting tools such as the Hospice Outcomes and Patient Evaluation (HOPE) instrument, which CMS is implementing as part of the Hospice Quality Reporting Program. Accurate documentation and coding support not only payment but also quality metrics that will increasingly shape public reporting and regulatory attention.

Practical Coding Pitfalls That Drive Hospice Denials

In our work helping agencies clean up hospice AR, we see the same coding and billing issues contributing to avoidable denials and delayed cash.

A frequent problem is miscoding the level of care on days where the clinical team has shifted the plan. Documentation may show that a patient transitioned from routine home care to GIP during a symptom crisis, but the claim still reflects revenue code 0651 for the full billing period. This leads to inconsistent records and, when audited, can generate recoupment for days that should have been billed as GIP. It is also critical to accurately record the patient’s death date in hospice and inpatient care documentation, as billing and payment policies are often triggered by the date of death. Properly documenting the death date ensures compliance and that services provided up to that point are billed at the correct rate.

Another common issue is related to continuous home care. Teams sometimes provide a substantial amount of skilled care in the home during a crisis but fail to track the total hours and disciplines involved in a way that supports CHC billing. As a result, those days are billed as routine home care, and the agency leaves legitimate revenue unclaimed.

We also see operational gaps around the two-tier RHC structure. Without a clear process to track day counts from the start of each hospice election, billing staff may incorrectly apply the higher day 1–60 rate beyond the allowable window or default to the lower rate when they could legitimately bill the higher one. Both scenarios represent financial leakage.

These coding pitfalls intersect directly with denial patterns we have covered in more depth in our hospice denial management resources. For example, earlier content on hospice claims denial management and hospice denial workflows highlights how late NOEs, missing physician certifications, and sequential billing errors show up as return-to-provider claims and extended AR days. A focused hospice billing code review often complements those broader denial management efforts by making sure each day on each claim is coded to match the care actually delivered.

For additional depth on denial trends and workflows, you may find it useful to review our hospice claims denial management guide and our hospice denial management workflow article, which walk through step-by-step processes to address and prevent the most common hospice-specific denials.

Integrating Hospice Billing Codes Into a Reliable Workflow

Getting hospice codes right is less about memorizing every possible revenue code and more about building a repeatable process that connects clinical documentation, coding, and billing.

Hospice agencies that manage this well tend to have a few characteristics.

They treat the level of care decision as a documented clinical judgment, not a billing afterthought. Daily IDG or nursing notes clearly state whether the patient is routine home care, continuous home care, inpatient respite, or GIP, and why. That makes it straightforward for coders to select the correct revenue code and for auditors to follow the clinical rationale.

They maintain a single source of truth for hospice election dates, benefit periods, and day counts. This allows billing staff to know exactly when a patient transitions from the higher to the lower RHC rate tier and to keep sequential billing accurate. When this data is scattered across spreadsheets and EHR screens, errors multiply.

They close the loop between denials and coding. When payers deny or recoup hospice days based on medical necessity, level of care, or diagnosis concerns, those findings are translated into practical coding guidelines and staff education rather than treated as one-off frustrations.

Finally, they use clear leadership reporting to track hospice-specific metrics such as routine home care mix, CHC utilization, inpatient day percentages, and denial rates by reason code. That kind of reporting, which we emphasize in our broader revenue cycle work, helps leadership identify whether a billing issue is isolated or systemic.

If you are already working on optimizing healthcare accounts receivable, aligning hospice coding and billing with your AR clean-up and denial management efforts will usually produce faster, more reliable cash flow impact than tackling each issue in isolation. Additionally, agencies should provide a clear contact for billing questions or support related to hospice billing codes to ensure staff and stakeholders can quickly resolve issues and maintain workflow efficiency.

Conclusion: Coding Detail Is Financial Stability

Hospice operates in a payment environment where your margin for billing error is narrow and your clinical mission is demanding. The combination of fixed per diem payments, tiered routine home care rates, inpatient day caps, and detailed election rules means your billing codes must consistently reflect reality.

By grounding your hospice billing in a clear understanding of the four levels of care, accurate diagnosis coding, and disciplined NOE and sequential billing processes, you support both compliance and financial stability. That, in turn, gives your team more room to focus on what matters most: providing high-quality end-of-life care to patients and families.
