(i) Non-indigent beneficiary. A non-indigent beneficiary is a beneficiary who has not been determined to be categorically or medically needy by a State Medicaid Agency to receive medical assistance from Medicaid, nor have they been determined to be indigent by the provider for Medicare bad debt purposes. To be considered a reasonable collection effort for non-indigent beneficiaries, all of the following are applicable:
(A) A provider's collection effort or the effort of a collection agency acting on the provider's behalf, or both, to collect Medicare deductible or coinsurance amounts must consist of all of the following:
(1) Be similar to the collection effort put forth to collect comparable amounts from non-Medicare patients.

(3) For cost reporting periods beginning on or after October 1, 2020, involve the issuance of a bill to the beneficiary or the party responsible for the beneficiary's personal financial obligations on or before 120 days after the latter of one of the following:
(i) The date of the Medicare remittance advice that results from processing the claim for services furnished to the beneficiary and generates the beneficiary's cost sharing amounts.
(ii) The date of the remittance advice from the beneficiary's secondary payer, if any.
(iii) The date of the notification that the beneficiary's secondary payer does not cover the service furnished to the beneficiary.
(4) Include other actions such as subsequent billings, collection letters, and telephone calls, emails, text messages, or personal contacts with this party.
(5)(i) Last at least 120 days after paragraph (e)(2)(i)(A)(2) or (3) of this section is met before being written off as uncollectible under paragraph (e)(3) of this section.

(ii) The patient account history documents which show the dates of various collection actions such as the issuance of bills to the beneficiary, follow-up collection letters, reports of telephone calls and personal contact, etc.
(iii) The beneficiary's file with copies of the bill(s) and follow-up notices.
(B) A provider that uses a collection agency to perform its collection effort must do all of the following:
(1) Reduce the beneficiary's account receivable by the gross amount collected.
(2) Include any fee charged by the collection agency as an administrative cost.
(3) Before claiming the unpaid amounts as a Medicare bad debt, cease all collection efforts, including the collection agency efforts, and ensure that the collection accounts have been returned to the provider from the agency.
(ii) Indigent non-dual eligible beneficiary. An indigent non-dual eligible beneficiary is a beneficiary who is determined to be indigent or medically indigent by the provider and is not eligible for Medicaid as categorically or medically needy.
(A) To determine a beneficiary to be an indigent non-dual eligible beneficiary, the provider—
(1) Must not use a beneficiary's declaration of their inability to pay their medical bills or deductibles and coinsurance amounts as sole proof of indigence or medical indigence;
(2) Must take into account the analysis of both the beneficiary's assets (only those convertible to cash and unnecessary for the beneficiary's daily living) and income;
(3) May consider extenuating circumstances that would affect the determination of the beneficiary's indigence or medical indigence which may include an analysis of both the beneficiary's liabilities and expenses, if indigence is unable to be determined under paragraph (e)(ii)(A)(2) of this section;
(4) Must determine that no source other than the beneficiary would be legally responsible for the beneficiary's medical bill, such as a legal guardian or State Medicaid program; and
(5) Must maintain and, upon request, furnish its contractor its indigence policy describing the method by which indigence or medical indigence is determined and all the verifiable beneficiary specific documentation which supports the provider's determination of each beneficiary's indigence or medical indigence.
(iii) Indigent dual-eligible beneficiaries (including qualified Medicare beneficiaries). Providers may deem Medicare beneficiaries indigent or medically indigent when such individuals have also been determined eligible for Medicaid under a State's Title XIX Medicaid program as either categorically needy individuals or medically needy individuals. To be considered a reasonable collection effort for dual-eligible beneficiaries:
(A) When a State permits a Medicare provider's Medicaid enrollment for the purposes of processing a beneficiary's claim, to determine the State's liability for the beneficiary's Medicare cost sharing, the provider—
(1) Must determine whether the State's Title XIX Medicaid Program (or a local welfare agency, if applicable) is responsible to pay all or a portion of the beneficiary's Medicare deductible or coinsurance amounts;
(2) Must submit a bill to its Medicaid/Title XIX agency (or to its local welfare agency) to determine the State's cost sharing obligation to pay all or a portion of the applicable Medicare deductible and coinsurance;
(3) Must submit the Medicaid remittance advice received from the State to its Medicare contractor;
(4) Must reduce allowable Medicare bad debt by any amount that the State is obligated to pay, either by statute or under the terms of its approved Medicaid State plan, regardless of whether the State actually pays its obligated amount to the provider; and
(5) May include the Medicare deductible or coinsurance amount, or any portion thereof that the State is not obligated to pay, and which remains unpaid by the beneficiary, as an allowable Medicare bad debt.
(B) When, through no fault of the provider, a provider does not receive a Medicaid remittance advice because the State does not permit a Medicare provider's Medicaid enrollment for the purposes of processing a beneficiary's claim, or because the State does not generate a Medicaid remittance advice, the provider—
(1) Must submit to its contractor, all of the following auditable and verifiable documentation:
(i) The State's Medicaid notification stating that the State has no legal obligation to pay the provider for the beneficiary's Medicare cost sharing.
(ii) A calculation of the amount the State owes the provider for Medicare cost sharing.
(iii) Verification of the beneficiary's eligibility for Medicaid for the date of service;
(2) Must reduce allowable Medicare bad debt by any amount the State is obligated to pay, regardless of whether the State actually pays its obligated amount to the provider; and
(3) May include the Medicare deductible or coinsurance amount, or any portion thereof that the State is not obligated to pay, and which remains unpaid by the beneficiary, as an allowable Medicare bad debt.
(f) Reporting period for writing off bad debts and reporting of recoveries of bad debts reimbursed in prior periods. For cost reporting periods beginning before, on, or after October 1, 2020, the deductible and coinsurance amounts uncollected from beneficiaries are to be written off and recognized as allowable bad debts in the cost reporting period in which the accounts are deemed to be worthless.
(2) In some cases an amount written off as a bad debt and reimbursed by the program in a prior cost reporting period may be recovered in a subsequent period.
(2) Skilled nursing facilities and swing bed hospitals. For the purposes of this paragraph (h)(2), a dual eligible individual is defined as an individual that is entitled to benefits under Part A of Medicare and is determined eligible by the State for medical assistance under Title XIX of the Act as described under paragraph (2) of the definition of a “full-benefit dual eligible individual” at § 423.772 of this chapter. In determining reasonable costs for a skilled nursing facility and for post-hospital SNF care furnished in a swing bed hospital, as defined in § 413.114(b), the amount of allowable bad debt (as defined in paragraph (e) of this section) is reduced:
(3) End-stage renal dialysis facilities. In determining reasonable costs for an end-stage renal dialysis facility, the amount of allowable bad debt (as defined in paragraph (e) of this section) is:
(4) All other providers. In determining reasonable costs for all other providers, suppliers and other entities not described elsewhere in paragraph (h) of this section that are eligible to receive reimbursement for bad debts under this section, the amount of allowable bad debts (as defined in paragraph (e) of this section) is reduced:
