HCPCS code T2042 – Hospice routine home care

Key takeaways

HCPCS Code T2042 pays a hospice for one day of routine home care under state Medicaid or a Medicaid managed care plan.

Medicare Part A hospice claims never carry T2042. They report routine home care with revenue code 0651 instead.

T2042 is one of five level-of-care codes, T2042 to T2046, and the clinical record decides which code each day gets.

Bill one unit per calendar day, however many disciplines visited, and check the state’s rules on span dates and same-day level changes.

Claims management software with claim validation, such as Pabau’s, catches unit and code errors before the claim reaches the payer.

HCPCS Code T2042: Official descriptor and coverage definition

HCPCS Code T2042 is a T-series code among the HCPCS Level II codes, with the official descriptor Hospice routine home care; per diem. The Centers for Medicare and Medicaid Services (CMS) maintains HCPCS Level II. It reserves the T-series for state Medicaid agencies, covering services that have no permanent national code.

Routine home care is the most frequently billed hospice level of care. It applies on any day a hospice patient receives care at home and needs neither continuous nursing nor an inpatient bed. The per diem rate covers an entire calendar day, not a specific visit duration.

Key definitional facts about HCPCS Code T2042:

• Code type: HCPCS Level II, T-series (state Medicaid agency codes)
• Official descriptor: Hospice routine home care; per diem
• Billing unit: 1 unit = 1 calendar day
• Primary payer: State Medicaid programs and Medicaid managed care organizations
• Not applicable to: Medicare Part A hospice claims (billed on the UB-04 with revenue codes 0651, 0652, 0655 and 0656)

Fee schedule and reimbursement rates for T2042

Each state Medicaid agency sets its own T2042 per diem rate, so there is no single national fee schedule. CMS publishes annual hospice payment rates that states use as a baseline. What a hospice receives for HCPCS Code T2042 then depends on the state and on any Medicaid managed care contract in place.

T-codes are not paid by Medicare, so the Medicare Physician Fee Schedule carries no T2042 rate. Look up the current rate in your state Medicaid fee schedule or provider manual. The table below shows how each hospice code is paid, and the rate itself always comes from the state.

Rates typically follow CMS’s annual hospice wage-index updates. Verify the current rate for your state by consulting the relevant Medicaid provider bulletin before the start of each fiscal year. Billing a stale rate from a prior-year fee schedule is a common and avoidable source of underpayment.

T2042 vs T2043, T2044, T2045, and T2046: Hospice level-of-care codes compared

Choosing the wrong code from the T2042-T2046 range is a frequent cause of hospice Medicaid denials. Each code maps to a distinct level of care, and the clinical record must support the code billed on each day. The diagram below walks one hospice day through both decisions: the payer first, then the level of care.

The table adds the mix-up each code is most prone to.

Some days cross levels, such as routine care in the morning and continuous care from the afternoon. The rule for same-day changes is payer-specific, so check the state Medicaid or managed care policy before submitting.

Crisis days follow the hourly unit rules covered under T2043. Nursing facility residents also need a room and board line, explained under T2046.

Payer eligibility: Medicare vs. Medicaid vs. managed care

HCPCS Code T2042 is a Medicaid-specific code. It does not appear on Medicare Part A hospice claims. Sending it to Medicare gets the claim rejected, and billers often misread that rejection as a coding error when the payer is the problem.

Medicare Part A hospice claims report the level of care with UB-04 revenue codes 0651, 0652, 0655 and 0656 instead of HCPCS T-codes. T2042 lets state Medicaid agencies and their managed care plans pay each hospice level of care per diem, inside their own payment systems.

• Medicare Part A: Bill via UB-04 with revenue code 0651 (routine home care). Do NOT use T2042.
• Fee-for-service Medicaid: T2042 is the primary billing code. Rate is set by the state Medicaid agency fee schedule.
• Medicaid managed care (MCO): T2042 is accepted by most MCOs, but the contract rate may differ from fee-for-service. Confirm the plan’s specific hospice billing requirements and modifier requirements before submitting.
• Dual-eligible patients: Medicare Part A is always the primary payer for hospice services on dual-eligible beneficiaries. Medicaid (and by extension T2042) only applies to services not covered by Medicare Part A or as a wraparound for cost-sharing.

Before billing T2042, confirm that the patient has elected the hospice benefit. A valid election statement must be on file for the billing period.

Documentation requirements for T2042

Every T2042 claim needs a clinical record that shows the patient’s hospice eligibility and the level of care given on the billed date. Missing or incomplete documentation is among the top reasons for medical billing compliance failures during post-payment audits.

Required documentation for each T2042 claim date:

• Physician certification of terminal illness: A signed certification from the attending physician and the hospice medical director. It confirms a life expectancy of six months or less if the illness runs its normal course, and it is renewed for each benefit period.
• Patient election statement: Signed document confirming the patient (or representative) has elected the hospice benefit and understands it replaces curative treatment for the terminal condition.
• Plan of care: An individualized plan of the services to be provided and the patient’s current status. The hospice team reviews and revises it at least every 15 days for the whole benefit period.
• Daily service log: A record of every service on the billed date. It confirms that a care team visit or remote contact took place at the routine home care level.
• Benefit period documentation: Records showing the patient is in an open benefit period on the claim date. Periods run 90 days, 90 days, then unlimited 60-day periods.

Services included and excluded under T2042

The T2042 per diem rate is an all-inclusive payment. Services rendered on a routine home care day are bundled into a single daily rate and must not be billed separately. Unbundling is an OIG audit trigger and a direct route to overpayment recoupment.

A non-hospice provider who treats a hospice patient for an unrelated condition may bill that service outside the hospice benefit. The hospice agency is not responsible for those claims. Document the distinction clearly in the medical record.

Required modifiers and claim line configuration for HCPCS Code T2042

Modifier requirements for HCPCS Code T2042 vary by payer. The modifiers below are widely recognized on Medicaid and managed care hospice claims. Always confirm them against the state Medicaid provider manual or MCO contract. Incorrect modifier use generates denials that are often not correctable on resubmission.

Billing unit rule: Bill exactly 1 unit of T2042 per calendar day, regardless of how many disciplines visited the patient on that date. The per diem pays for the full day of routine home care. A claim with more than one unit per day denies, and the only fix is to void and resubmit it.

How to bill T2042: Step-by-step claim submission

Hospice Medicaid claims using HCPCS Code T2042 are typically submitted on the UB-04 claim form. The steps below reflect standard practice, though specific field requirements can vary by state Medicaid system or MCO. Refer to the AAPC hospice code range for the current descriptors before submitting an unfamiliar claim setup.

1. Confirm active hospice enrollment: Verify the patient’s election of hospice benefit and that the current benefit period is open on the claim date. A lapsed benefit period generates an automatic denial.
2. Select the correct LOC code: Confirm the clinical record supports T2042 (routine home care) on the billed date. If the record shows 8+ hours of crisis care, mostly nursing, bill T2043 by the hour instead.
3. Complete the UB-04 revenue code field: Revenue code 0651 accompanies T2042 on most state Medicaid UB-04 claims. Verify the pairing with the applicable provider manual.
4. Enter HCPCS Code T2042 in Form Locator 44: Record the code with 1 unit in Form Locator 46. Do not span-bill multiple days on a single claim line using a date range without confirming that the payer accepts span-date billing for T-series codes.
5. Check modifier requirements: GV and GW belong on the claims of non-hospice providers who treat the patient, not on the T2042 line. Add a modifier to T2042 only where the state manual or MCO contract requires one.
6. Verify coordination of benefits: For dual-eligible patients, confirm Medicare Part A is the primary payer. T2042 applies only to services not covered under Medicare Part A or as a cost-sharing wrap.
7. Submit electronically and retain supporting documentation: Keep the daily service log, election statement, plan of care, and physician certification accessible for audit requests.

Common denial reasons for T2042 claims and how to avoid them

T2042 claim denials cluster around a predictable set of billing errors. The table below maps each denial trigger to its root cause and the specific fix to apply on resubmission or, better, before initial submission.

Building a denial management workflow that tracks T2042 denial CARC codes by root cause shows which errors repeat. If three or more claims in a rolling month share a denial trigger, fix the step that produces it before resubmitting.

How claims management software prevents T2042 denials

Many hospice billers still check each T2042 claim date by hand. They match the payer, the level of care and the unit count against the election statement, the certification and the daily log.

Pabau, the practice management platform we build, raises each claim from the patient’s invoice. Its claims management software validates the claim for missing or invalid details before it reaches your clearinghouse. An eligibility check before the visit confirms coverage, too.

The election statement, plan of care and visit notes sit in the same patient record, so an auditor’s request takes minutes. Every claim’s status shows on one dashboard, with rejected claims marked Needs action for your team to fix.

Catch T2042 claim errors before submission

Pabau validates each hospice claim for missing or invalid details before it reaches your clearinghouse, so your team spends less time reworking denials.

Conclusion

Getting paid for T2042 comes down to three checks per claim date. The payer must take T-codes, the record must support routine home care, and the election and certification must cover the date.

Build those checks into claim preparation rather than the denial queue. A hospice that runs them on every date bills one clean unit a day and has its audit file ready before anyone asks.

To see how Pabau runs those checks before each T2042 claim goes out, book a demo.
