HCPCS code T2045 – Hospice general inpatient care per diem

Key takeaways

HCPCS code T2045 bills one calendar day of hospice general inpatient care (GIP), and the hospice submits the claim rather than the facility.

A patient qualifies for GIP only when pain or acute symptoms cannot be managed in any other setting, per 42 CFR §418.108.

T2045 is mainly a Medicaid managed care and commercial payer code. Medicare fee-for-service pays GIP at its own per diem rate instead.

On the UB-04, a T2045 line carries revenue code 0656, bill type 081X and one unit per calendar day.

Most denials come from billing respite care (T2044) in place of T2045, or from a missing Notice of Election (NOE).

HCPCS code T2045: Official descriptor and code classification

HCPCS code T2045 is the HCPCS Level II code a hospice uses to bill one day of general inpatient care (GIP). Its official descriptor reads “Hospice general inpatient care; per diem.” GIP is short-term inpatient care for pain or symptoms that no other setting can manage.

T2045 sits in the T-code series, which covers state Medicaid agency and managed care services that CPT and other HCPCS sections leave out. That is why Medicaid managed care and commercial plans ask for it, while Medicare fee-for-service does not.

CMS maintains the series and updates it every year through the CMS HCPCS Level II code system. Our searchable HCPCS code library lists the other T-codes next to T2045.

T2045 is active for 2026 with no changes to its descriptor or status from the prior year. The table below places it within the T2042-T2046 hospice family and shows each code’s billing unit.

What T2045 covers and what it excludes

T2045 reimburses one calendar day of general inpatient hospice care. That day covers the full scope of GIP services the hospice interdisciplinary group (IDG) delivers in an inpatient setting.

Covered under T2045:

• 24-hour skilled nursing care for acute pain or symptom management
• Room and board in a hospital, skilled nursing facility (SNF), or designated inpatient hospice unit
• Medications, supplies, and equipment needed for GIP-level symptom control
• Interdisciplinary team services (social work, chaplaincy, counseling) during the GIP stay
• Medical direction oversight from the hospice attending physician

Not covered by T2045:

• Routine home care (T2042), even if the patient is in a facility
• Inpatient respite care (T2044), which is for caregiver relief, not acute symptom management
• Continuous home care (T2043), which applies in the home setting only
• Attending physician professional services billed separately under Part B
• Non-hospice inpatient services unrelated to the terminal diagnosis

The distinction between T2044 and T2045 is the most common source of wrong-code denials. Respite care (T2044) is time-limited relief for the primary caregiver. General inpatient care (T2045) is for acute medical crisis management the patient cannot receive at home. The clinical reason for admission determines which code applies.

GIP level of care: Who qualifies for hospice general inpatient care

A patient qualifies for GIP when pain or acute symptom management requires inpatient-level care that cannot be provided in the home or any other setting. This threshold is set by federal regulation at 42 CFR §418.108 and must be documented before every GIP admission.

The hospice IDG must determine that GIP is necessary and the plan of care must reflect that determination. CMS audits routinely look for the following documentation elements to support GIP necessity.

• IDG clinical determination: The team’s assessment that symptoms are unmanageable in any other setting
• Physician narrative or attestation: Supporting the need for inpatient-level care, linked to the terminal diagnosis
• Nursing notes: Documenting the specific uncontrolled symptoms (pain scores, vomiting frequency, respiratory distress, agitation levels)
• Plan of care update: Reflecting the GIP level and the expected clinical goals of the inpatient stay
• Facility nursing notes: Corroborating that the inpatient facility is actively providing the level of care that GIP requires

GIP is intended as short-term. Extended stays are subject to clinical review by the payer. Some managed care plans impose internal day limits on GIP authorization, so check payer-specific hospice clinical policies before admitting patients for extended GIP stays.

How HCPCS code T2045 is billed: Per diem mechanics and the UB-04

T2045 is billed per diem, so one unit equals one calendar day of GIP care. The hospice provider submits the claim, not the hospital or SNF where care is delivered. When a patient receives GIP in a hospital, the hospital bills its facility costs separately and the hospice bills T2045 for its own services.

Claims go on the UB-04 (CMS-1450) institutional claim form. If institutional claims are new to your team, start with these medical billing fundamentals. The table below summarizes the key UB-04 fields for T2045 claims, based on CMS hospice claim requirements.

Revenue codes and UB-04 requirements for T2045

A Notice of Election (NOE) must be filed with the payer before any hospice claim, including T2045, can be reimbursed. Without a timely NOE, the hospice cannot receive payment for any level of care. Billing teams that track NOE status in denial-reducing claims software can confirm it before a GIP claim goes out.

T2045 vs neighboring hospice codes T2042-T2046

The T2042-T2046 range covers all four Medicare-defined hospice levels of care, plus long-term care room and board. Knowing which code maps to which clinical level prevents the most common wrong-code denials. Crisis care delivered at home is billed under T2043, and facility room and board falls under T2046.

Choosing between T2044 and T2045 turns on why the patient is in the inpatient facility. A stay for caregiver relief is T2044, and a stay for an acute symptom crisis is T2045. Payer reviewers apply exactly that test, so document the clinical reason for every admission.

The chart below starts from that reason and ends at the UB-04 line a GIP day needs.

Documentation requirements for T2045 claims

T2045 claims are among the most documentation-intensive in hospice billing. CMS and managed care payers require a complete clinical record that supports GIP necessity for each admitted day, not just the admission date. Sound medical billing compliance practices reduce that audit exposure.

The mandatory documentation set for T2045 includes all of the following.

• Filed Notice of Election (NOE): Must be submitted to the payer within the timely filing limit before any hospice billing. A late or missing NOE means automatic denial
• Certification of terminal illness: Signed by the attending physician and hospice medical director. It confirms a life expectancy of six months or less if the illness follows its normal course
• Updated plan of care: Reflecting GIP-level care, the specific clinical goals, and the IDG’s determination that inpatient care is medically necessary
• IDG clinical documentation: Meeting notes, assessments, and care decisions supporting GIP need
• Physician attestation: Narrative or attestation linking the inpatient admission to uncontrolled symptoms from the terminal diagnosis
• Facility nursing notes: Contemporaneous documentation of symptom severity and the interventions being delivered at the inpatient level
• Discharge or transition note: Documenting when and why the patient returned to routine home care or another level of care

Keep all documentation in a single accessible record. When a payer requests supporting documentation for a T2045 claim, the response window is typically short. Records scattered across several systems are a common reason practices lose appeals they could have won.

Payer requirements: Medicare, Medicaid, and commercial plans

Whether a payer accepts T2045 depends on the payer type. Confusing Medicare fee-for-service with Medicaid managed care is the costliest mistake in hospice HCPCS billing.

Medicare fee-for-service: Medicare does not reimburse GIP using T2045 directly. Under the Medicare hospice benefit, CMS pays the hospice a GIP per diem rate adjusted by the hospice wage index. The hospice bills Medicare on the UB-04 with revenue code 0656, and CMS applies the GIP rate without requiring T2045 in FL 44.

The current GIP base rate is set in the annual CMS Hospice Wage Index Final Rule, which CMS posts on its hospice payment page.

Medicaid managed care and commercial plans: T2045 is the active code for these payers. Managed care organizations typically require the HCPCS code on the claim alongside the revenue code. Prior authorization rules vary, since some plans require it for GIP admissions and others do not.

Always check the payer’s hospice clinical policy before admission. A denial for missing prior authorization usually cannot be fixed after the fact.

T2045 reimbursement rates in 2026

For Medicare fee-for-service, the GIP per diem rate is set annually through the CMS Hospice Wage Index Final Rule. The 2026 base rates are adjusted by each hospice provider’s geographic wage index. CMS publishes the final figures in the Federal Register and on CMS.gov.

The table below shows the approximate 2026 Medicare GIP rate structure by setting. Because rates carry a wage index multiplier, the amount paid differs by location. Confirm the current year’s rates in the final rule before you use them for budgets or contract negotiations.

Medicaid rates for T2045 are state-determined and not published in a single federal source. Contact your state Medicaid agency or review your managed care organization contracts for the applicable rate. Verify annually, as Medicaid T2045 rates are subject to state budget cycles independent of the CMS federal rule cycle.

Common billing errors and claim denials for HCPCS code T2045

T2045 denial rates in hospice billing are driven by a short list of recurring errors. Most are preventable with pre-submission checks. Effective denial management workflows catch these before the claim leaves the billing team.

T2045 appeals are winnable when the clinical record is complete. The appeal packet should include these four documents.

• The complete plan of care
• The physician attestation
• Facility nursing notes from the GIP stay
• A written explanation of why the clinical criteria were met

Most managed care plans allow 60-180 days from the denial date to file an appeal. The AAPC HCPCS code reference helps you confirm code requirements as you build the appeal narrative.

How Pabau supports hospice billing workflows

Many hospice billing teams keep the GIP clinical record in one system and build the claim in another. Each handoff between them is a chance to lose an attestation or bill the wrong level of care.

Pabau keeps the clinical record and the outgoing claim in one place. Its digital forms hold plan of care templates, IDG notes and physician attestations. Each GIP day then has its documentation attached before the claim is built.

Claim status tracking lets billing managers follow T2045 submissions by patient. They can clear outstanding items before timely filing windows close, rather than finding them at payment posting.

Practices that bill hospice alongside other specialties get the same superbill preparation and denial tracking on every billing line. A team juggling T-codes, E/M visits and procedure billing across payers then works from one view of its denials.

Conclusion

T2045 pays only when the chart proves the crisis. Before you bill a GIP day, check that the nursing notes and IDG determination show why no other setting could manage the patient. If they do not, the day belongs under a different level of care.

The payer decides the rest. Medicaid managed care and commercial plans want T2045 on the claim, often with prior authorization, while Medicare fee-for-service pays GIP through revenue code 0656 alone. Settle which rules apply at admission, and appeals become rare rather than routine.

Pabau links each GIP day’s documentation to its claim, so your team spends less time rebuilding records for appeals. Book a demo to see how it keeps T2045 claims clean from admission through payment.
