Common questions about End Stage Renal Disease and Medicare

End-Stage Renal Disease (ESRD) means permanent kidney failure requiring dialysis or a kidney transplant. Medicare may be available to people of any age who meet its medical and work or family benefit requirements. This independent tool estimates dates and helps you prepare questions for Medicare and your other insurance plans.

When might Medicare start after in-center dialysis begins?

For regular in-center dialysis, ESRD Medicare entitlement generally begins on the first day of the fourth month of dialysis. The month dialysis begins counts as month one. A qualifying home dialysis training program or kidney transplant may allow an earlier date. Your actual coverage depends on enrollment and Medicare's determination.

Does a kidney transplant change the start date?

It can. Medicare may begin in the month of a qualifying hospital admission for transplant, within Medicare's timing rules, or in the transplant month. A transplant during an existing period of ESRD entitlement does not by itself restart the 30-month coordination period.

Who pays first when I have an employer or union health plan?

The employer or union group plan generally pays first during the 30-month ESRD coordination period, which starts with the first month you qualify for ESRD Medicare even if you enroll later. If Medicare was already paying first because of age or disability, the payer order can differ. After the period, Medicare generally pays first if it is active, and the group plan may pay second if still in place.

What if I also have Marketplace, Medicaid, or VA coverage?

The 30-month employer-plan rule does not make these plans pay first. Medicare generally pays before Medicaid for Medicare-covered services. Medicare and VA generally do not pay for the same service. A Marketplace plan does not end automatically when Medicare starts; ask about ending the covered person's Marketplace coverage and any financial help. Multiple coverages need an individual review.

When can Medicare based only on kidney failure end?

It generally ends 36 months after the month of a successful kidney transplant, or 12 months after dialysis stops without transplant. Another transplant, resumed dialysis, or Medicare eligibility due to age or disability can change what happens next.

What Medicare costs

Medicare Part A has no monthly premium for many people who qualify. Part B usually has a monthly premium, an annual deductible, and a share of costs for covered services. The premium can change each year and may be higher based on income. This tool estimates the full Part B premium, not the separate Part B immunosuppressive-drug-only benefit.

Estimate your current-year Part B premium

Social Security usually uses a tax return from two years earlier to set an income-based premium; it may use an earlier return if that one is unavailable. Choose the filing status and modified adjusted gross income (MAGI) range on the return Social Security uses. This is tax-return income, not current take-home pay or the income of everyone in your home.

Estimated current-year Part B premiumChecking current CMS figures…This is an estimate; Social Security makes the actual determination.

This estimate does not include a possible late-enrollment penalty. If Social Security has given you a different premium, or your income has fallen because of a qualifying life change, use its notice and ask about a review. Married people who filed separately but lived apart the entire year generally use the individual range. How Social Security sets premiums · Request an income-related premium review (SSA-44)

Help paying Medicare costs

Medicare Savings Programs are run by states. Depending on the program, they can pay the Part B premium and sometimes Medicare deductibles, coinsurance, and copayments. Income and resource rules vary by state; apply through your state even if you are unsure. Learn about Medicare Savings Programs.

Help with insurance premiums

The American Kidney Fund Health Insurance Premium Program (HIPP) may provide grants toward Part B and other insurance premiums for eligible people receiving dialysis. Ask your dialysis social worker about the application and other available assistance. Explore AKF HIPP.

Premium source: Medicare’s current cost information. The calculator displays an estimate only when it has a verified table for the displayed year.

Your ESRD Medicare enrollment choices

Enrolling is a choice. Before deciding, compare your current insurance costs, who pays first, your Part B premium, and how transplant medicines would be covered. These three paths can have very different consequences:

Part A only

Part A helps pay for inpatient hospital care, but it does not provide Part B's outpatient and doctor coverage. If you later want Part B, you may have to wait for the General Enrollment Period, January 1–March 31, unless another enrollment period applies. Part B normally starts the month after you sign up. A late enrollment penalty may apply: generally 10% of the Part B premium for each full 12 months you could have had Part B but did not. Ask Social Security to review any exception before choosing this path.

Parts A and B

This gives you Medicare's hospital and medical coverage. Part B has a monthly premium, but it may help with Medicare-covered costs that your employer plan leaves during the 30-month coordination period. For a qualifying kidney transplant, Part A at the time of transplant and active Part B when prescriptions are filled are especially important for Part B coverage of anti-rejection medicines.

Wait to enroll in both

If you have employer or union group coverage, you may decide to delay both parts during the 30-month period. Medicare says this may make sense when that plan covers most costs, and delaying both parts in this situation does not by itself raise your Part B premium. Check when your other coverage could change, and plan your Medicare application before the group plan stops paying first. Waiting may also affect future transplant drug coverage.

The Part B penalty depends on your specific enrollment history. Under Social Security's rules, months from a separate ESRD or disability entitlement before age 65 are not automatically carried into a later entitlement period; a penalty also resets at age 65. Ask Social Security to calculate your dates and premium. Compare ESRD enrollment paths and read Social Security's penalty rule.

When does Part B cover transplant medicines?

For someone who has Medicare only because of ESRD, Part B generally covers immunosuppressive (anti-rejection) medicines after a qualifying kidney transplant if Part A was in effect at the time of transplant, the transplant took place at a Medicare-certified facility, and Part B is active when the prescription is filled. Part B does not pay retroactively for medicines filled before Part B begins.

Example A — Part B can cover the medicines

Alex had Part A when the transplant took place at a Medicare-certified hospital. Alex later added Part B. Once Part B became active, it could help pay for eligible anti-rejection prescriptions. If Alex later qualifies for full Medicare because of age or disability, Part B coverage of those medicines can continue while the coverage requirements are met.

Example B — Part B cannot cover them

Sam did not have Part A at the transplant and cannot establish Part A coverage for that date. Adding Part B later does not make these transplant medicines eligible for ordinary Part B coverage. Sam should ask about other drug coverage, such as Part D or another health plan, before any coverage changes.

If ESRD-only Medicare ends 36 months after a successful transplant, a separate Part B Immunosuppressive Drug benefit (Part B-ID) may be available to people who meet its requirements and do not have disqualifying other health coverage. It covers eligible anti-rejection medicines only, not other medical care. Read Medicare's transplant drug guide and Part B-ID eligibility rules.

Respuestas claras, a su ritmo

Preguntas comunes sobre la enfermedad renal en etapa terminal y Medicare

La enfermedad renal en etapa terminal (ESRD) puede requerir diálisis o un trasplante de riñón. Medicare puede estar disponible para personas de cualquier edad que cumplan sus requisitos médicos y laborales o familiares. Esta herramienta independiente estima fechas y le ayuda a preparar preguntas para Medicare y sus otros seguros.

¿Cuándo podría comenzar Medicare después de iniciar diálisis en un centro?

Por lo general, el derecho a Medicare por ESRD comienza el primer día del cuarto mes de diálisis regular en un centro. El mes en que comienza la diálisis cuenta como mes uno. El entrenamiento elegible para diálisis en casa o un trasplante puede permitir una fecha anterior. La cobertura real depende de la inscripción y la determinación de Medicare.

¿Puede un trasplante cambiar la fecha de inicio?

Sí. Medicare puede comenzar en el mes de una hospitalización elegible para trasplante, según sus reglas de tiempo, o en el mes del trasplante. Un trasplante durante un período continuo de Medicare por ESRD no reinicia automáticamente el período de coordinación de 30 meses.

¿Quién paga primero si tengo un plan de empleador o sindicato?

El plan grupal generalmente paga primero durante el período de coordinación de 30 meses por ESRD, que comienza el primer mes en que califica aunque se inscriba después. Si Medicare ya pagaba primero por edad o discapacidad, el orden puede ser distinto. Después del período, Medicare generalmente paga primero si está vigente y el plan grupal puede pagar después si continúa.

¿Qué pasa si también tengo un plan del Mercado, Medicaid o VA?

La regla de 30 meses para planes grupales no obliga a estas coberturas a pagar primero. Medicare generalmente paga antes que Medicaid por servicios cubiertos por Medicare. Medicare y VA generalmente no pagan el mismo servicio. Un plan del Mercado no termina automáticamente cuando empieza Medicare. Si tiene varias coberturas, pida una revisión individual.

¿Cuándo puede terminar Medicare basado solo en la insuficiencia renal?

Generalmente termina 36 meses después del mes de un trasplante exitoso o 12 meses después de suspender la diálisis sin trasplante. Otro trasplante, reanudar diálisis o elegibilidad por edad o discapacidad pueden cambiar lo que sucede después.

Cuánto cuesta Medicare

Muchas personas que califican no pagan una prima mensual por la Parte A. La Parte B normalmente tiene una prima mensual, un deducible anual y una parte de los costos por servicios cubiertos. La prima puede cambiar cada año y ser más alta según los ingresos. Esta herramienta estima la prima de la Parte B completa, no el beneficio separado que solo cubre medicamentos inmunosupresores.

Estime su prima de la Parte B para el año actual

Por lo general, el Seguro Social usa una declaración de impuestos de dos años antes para fijar la prima basada en ingresos; puede usar una anterior si no tiene esa declaración. Elija el estado civil tributario y el rango de ingreso bruto ajustado modificado (MAGI) de la declaración que usa el Seguro Social. No se trata del sueldo neto actual ni de los ingresos de todas las personas que viven en su hogar.

Prima estimada de la Parte B para el año actualVerificando los datos actuales de CMS…Esta es una estimación; el Seguro Social determina la prima real.

Esta estimación no incluye una posible penalización por inscripción tardía. Si el Seguro Social le informó una prima diferente, o sus ingresos bajaron por un cambio de vida que cumple los requisitos, use su aviso y solicite una revisión. Las personas casadas que presentaron declaraciones separadas pero vivieron apartadas durante todo el año generalmente usan los rangos individuales.

Ayuda para pagar los costos de Medicare

Los Programas de Ahorro de Medicare son administrados por los estados. Según el programa, pueden pagar la prima de la Parte B y, en algunos casos, deducibles, coseguros y copagos de Medicare. Los requisitos de ingresos y recursos varían según el estado; solicite ayuda aunque no esté seguro de calificar. Conozca los Programas de Ahorro de Medicare.

Ayuda con las primas del seguro

El Programa de Primas de Seguro Médico (HIPP) del American Kidney Fund puede ofrecer subvenciones para pagar la Parte B y otras primas a personas elegibles que reciben diálisis. Pregunte a su trabajador social de diálisis sobre la solicitud y otras ayudas disponibles. Conozca AKF HIPP.

Sus opciones para inscribirse en Medicare por ESRD

Usted decide si se inscribe. Antes de hacerlo, compare los costos de su seguro actual, cuál paga primero, la prima de la Parte B y cómo se cubrirían los medicamentos después de un trasplante.

Solo la Parte A

La Parte A ayuda a pagar la hospitalización, pero no ofrece la cobertura médica ambulatoria de la Parte B. Si desea añadir la Parte B después, quizá tenga que esperar al Período General de Inscripción, del 1 de enero al 31 de marzo, salvo que corresponda otro período. La Parte B normalmente comienza el mes después de inscribirse. Podría aplicarse una penalidad: generalmente 10% de la prima de la Parte B por cada 12 meses completos en que pudo haber tenido la Parte B y no la tuvo. Pida al Seguro Social que revise las excepciones.

Partes A y B

Recibe cobertura hospitalaria y médica de Medicare. La Parte B tiene una prima mensual, pero puede ayudar con algunos costos que deja su plan de empleador durante el período de coordinación de 30 meses. Para cubrir medicamentos contra el rechazo después de un trasplante elegible, es especialmente importante tener la Parte A cuando se realiza el trasplante y la Parte B cuando surte las recetas.

Esperar para inscribirse en ambas

Si tiene cobertura de un empleador o sindicato, puede decidir esperar durante el período de 30 meses. Medicare indica que esto puede tener sentido si ese plan paga la mayoría de sus costos; esperar para inscribirse en ambas partes en esta situación no aumenta por sí solo la prima de la Parte B. Confirme cuándo puede cambiar su otro seguro y planifique la solicitud de Medicare. Esperar también puede afectar la cobertura futura de medicamentos del trasplante.

La penalidad depende de su historial de inscripción. Según el Seguro Social, los meses de un período separado de derecho a Medicare por ESRD o discapacidad antes de los 65 años no se trasladan automáticamente a un período posterior; la penalidad también se reajusta a los 65 años. Pida al Seguro Social que calcule sus fechas y su prima. Compare las opciones y consulte la regla del Seguro Social.

¿Cuándo cubre la Parte B los medicamentos del trasplante?

Para quien tiene Medicare solo por ESRD, la Parte B generalmente cubre los medicamentos inmunosupresores después de un trasplante elegible si la Parte A estaba vigente en el momento del trasplante, la cirugía se hizo en un centro certificado por Medicare y la Parte B está vigente cuando se surte la receta. No hay pago retroactivo por recetas surtidas antes de que comience la Parte B.

Ejemplo A — la Parte B puede cubrirlos

Alex tenía la Parte A al recibir el trasplante en un hospital certificado por Medicare. Después añadió la Parte B. Desde que comenzó la Parte B, esta podría ayudar a pagar las recetas elegibles. Si más adelante Alex obtiene Medicare completo por edad o discapacidad, la cobertura de esos medicamentos por la Parte B puede continuar si se cumplen los requisitos.

Ejemplo B — la Parte B no puede cubrirlos

Sam no tenía la Parte A al recibir el trasplante y no puede establecer cobertura de la Parte A para esa fecha. Añadir la Parte B después no hace que esos medicamentos cumplan los requisitos de la cobertura ordinaria de la Parte B. Sam debe consultar otras opciones, como la Parte D u otro seguro, antes de cambiar de cobertura.

Si Medicare basado solo en ESRD termina 36 meses después de un trasplante exitoso, el beneficio separado de medicamentos inmunosupresores de la Parte B (Part B-ID) podría estar disponible para quienes cumplan sus requisitos y no tengan otra cobertura que los excluya. Cubre solamente medicamentos elegibles contra el rechazo, no otros servicios médicos. Guía de Medicare y requisitos de Part B-ID.

      The ESRD group-plan rule applies regardless of employer size and to Medicare-covered services, not just kidney care. Gaining age/disability eligibility during an existing ESRD coordination period does not restart it. If the group plan ends, Medicare can pay first once effective. Confirm enrollment timing and any Part A-only history with Social Security before delaying Part B.

      After ESRD-based eligibility ends: at age 65 or older, coverage through your or your spouse’s current employment generally pays first with an employer of 20 or more employees. Under 65 with disability, coverage through your or a family member’s current employment generally pays first with 100 or more employees. Multi-employer rules can also apply. With smaller employers, retiree coverage, or COBRA, Medicare generally pays first. Confirm the coverage and employer size at that future date; this tool does not determine that later payer order.

      ESRD Medicare overview

      What is ESRD Medicare?

      • People of any age may qualify if ESRD medical and work/benefit-record requirements are met.
      • It may apply when chronic dialysis treatment is required or a kidney transplant has been completed.
      • Whether a person may qualify is one question; when to initiate ESRD Medicare is a separate planning question.
      • This calculator focuses on timing rules related to dialysis, home dialysis training, transplant hospitalization, and post-transplant dates.

      Why do the dates matter?

      • The ESRD Medicare entitlement date can affect when Medicare may begin.
      • It can also affect when the 30-month Coordination of Benefits period begins.
      • During that period, Medicare and another health plan may both apply, and payer order matters.

      How does someone apply for ESRD Medicare?

      • The CMS-43, Application for Hospital Insurance Benefits for Individuals with End Stage Renal Disease, is the application used to initiate the ESRD Medicare benefit.
      • Another form, the CMS-2728, End Stage Renal Disease Medical Evidence Report Medicare Entitlement and/or Patient Registration, is often requested.
      • If you have started dialysis treatment, or if your ESRD journey began with transplant, your dialysis or transplant team can provide a copy of the CMS-2728.
      • It is recommended that you send both the CMS-43 and CMS-2728 to your local Social Security Administration office to start the application process.

      Important terms

      • ESRD: End-Stage Renal Disease. For this Medicare tool, ESRD means kidney failure severe enough that chronic dialysis treatment is required, or a kidney transplant has been completed.
      • Entitlement date: The estimated date a person first becomes eligible for ESRD Medicare based on the treatment pathway.
      • 30-month Coordination of Benefits period: A 30-month period beginning the first month you qualify for ESRD Medicare, even if you have not signed up yet. Employer group coverage generally pays first during this period, but Medicare already primary through age/disability may remain primary.

      Primary Medicare and CMS resources

      Rules used

      In-center dialysis

      The entitlement date for ESRD Medicare generally begins on the 1st day of the 4th month of in-center dialysis, counting the month of the dialysis start date as month 1.

      Earlier transplant hospitalization

      Compare the dialysis start rule with the transplant rule and use the earlier qualifying date. A transplant during existing entitlement does not reset the original coordination period.

      Home dialysis

      Training at a Medicare-certified facility during the first 3 dialysis months; the doctor expects completion and self-dialysis at home; a regular course of dialysis continues during the waiting period.

      Transplant before dialysis

      If transplant occurs in the admission month or either of the next two months, use the qualifying admission month. If delayed longer, use two months before the transplant month. Without an earlier qualifying admission, use the transplant month.

      30-month Coordination of Benefits period

      The first ESRD eligibility month counts as month 1 even without enrollment; month 30 ends the coordination of benefits period. Payer order depends on group coverage and prior Medicare. Continuous entitlement keeps the original clock; new entitlement after termination may start a new period.

      After successful kidney transplant

      ESRD-only entitlement generally ends 36 months after the transplant month, or 12 months after dialysis stops without transplant. Resumed dialysis, another transplant, or age/disability eligibility can change this. Part B-ID does not extend full Medicare.

      Frequently asked questions

      What does End-Stage Renal Disease (ESRD) mean for Medicare?

      For the ESRD Medicare program, End-Stage Renal Disease generally means kidney failure severe enough that chronic dialysis treatment is required, or a kidney transplant has been completed. In practical terms, this calculator is focused on the Medicare timing rules that may apply when a person has started chronic dialysis, begins qualifying home dialysis training, or is hospitalized for a kidney transplant.

      When does Medicare start for in-center dialysis?

      The entitlement date for ESRD Medicare generally begins on the 1st day of the 4th month of in-center dialysis, counting the month of the dialysis start date as month 1.

      When does Medicare start for home dialysis?

      Training at a Medicare-certified facility during the first 3 dialysis months; the doctor expects completion and self-dialysis at home; a regular course of dialysis continues during the waiting period.

      What is the 30-month Coordination of Benefits period?

      The first ESRD eligibility month counts as month 1 even without enrollment; month 30 ends the coordination of benefits period. Payer order depends on group coverage and prior Medicare. Continuous entitlement keeps the original clock; new entitlement after termination may start a new period.

      Does the Coordination of Benefits period start if Medicare is not active yet?

      The 30-month ESRD Coordination of Benefits period is generally tied to the first month a person is eligible for ESRD Medicare, even if they do not enroll right away.

      When does ESRD Medicare end after kidney transplant?

      ESRD-only entitlement generally ends 36 months after the transplant month, or 12 months after dialysis stops without transplant. Resumed dialysis, another transplant, or age/disability eligibility can change this. Part B-ID does not extend full Medicare.
