Finding 2025-034 Compliance with Activities Allowed or Unallowed, Allowable Costs/Cost Principles, and Eligibility for Medicaid The Department is responsible for ensuring that all of its expenditures under the Medicaid program [ALN 93.778] are appropriate, and that it complies with federal and state program requirements. In Colorado, the responsibility for determining recipient eligibility for Medicaid program benefits is shared between local counties, designated Medical Assistance eligibility sites (MA sites), and the Department (in this case, the State). Individuals and families apply for Medicaid benefits at their local county departments of human/social services, designated MA sites, or online through the Department’s Program Eligibility and Application Kit (PEAK) system. Local counties and MA sites are responsible for administering the benefits application process, reviewing the PEAK system for application data, entering the required data for eligibility determination into the Colorado Benefits Management System (CBMS), and approving or denying an applicant’s eligibility based on program criteria. Federal regulations require state medical assistance programs to renew a beneficiary’s eligibility once every 12 months to determine whether the beneficiary continues to qualify for benefits (also known as redetermination). States must first attempt to redetermine the beneficiary’s eligibility based on information the Department has available at the time, either from the beneficiary’s case file or other electronic data sources, like PEAK and CBMS, without requiring information from the beneficiary. This is called an “ex parte” renewal. If sufficient information is available, the Department can renew eligibility on an ex parte basis and notify the beneficiary that their coverage has been renewed. If sufficient information is not available, the Department will provide the beneficiary with a renewal form and request any additional documentation needed to determine eligibility. Once the renewal forms are completed and returned to the Department for processing, the caseworker enters the applicant’s information into CBMS, and, once all required information is entered, they can mark the application as complete. At that point, CBMS determines the applicant’s eligibility based on the information entered. If the application is incomplete, a caseworker is responsible for contacting the individual to assist with completing their application. An eligible beneficiary’s income and countable resources cannot exceed a limit set by federal and state regulations. CBMS has a system check to mark eligibility as “fail” if the applicant’s reported income exceeds the limit. Eligibility data from CBMS feeds into the Colorado interChange system (Colorado interChange), which issues payments to Medicaid providers for the services that they provide to Medicaid beneficiaries. The Department pays for Medicaid services through one of two reimbursement methods: (1) fee-for-service (FFS) payments for specific services rendered or (2) capitation payments, monthly fixed payments that are paid to managed care entities (MCEs). Once a beneficiary is determined eligible, then they determine whether to enroll in FFS or an MCE. FFS reimbursements are paid directly to providers for services rendered. Capitation payments are paid to MCEs, which are groups or organizations of medical service providers who contract with a network of providers for services. The Department pays monthly capitation payments to MCEs on behalf of beneficiaries based on the number of eligible beneficiaries enrolled in its plan. These payments are made to the MCE regardless of whether the beneficiaries receive medical services during the month. Colorado interChange is programmed to pay the FFS and monthly capitation payments only on behalf of beneficiaries deemed eligible in Colorado interChange based on eligibility information received from CBMS and requirements specified in federal and state rules and regulations. The Department is responsible for supervising and monitoring the local counties’ and MA sites’ administration of Medicaid eligibility determinations. The Department is also responsible for ensuring that it only provides Medicaid payments to eligible providers for providing allowable services on behalf of Medicaid-eligible individuals. What was the purpose of our audit work and what work was performed? The purpose of our audit work was to determine whether the Department had appropriate internal controls over and complied with applicable federal and state Medicaid eligibility requirements during Fiscal Year 2025. Another purpose of our audit work was to determine whether the Department implemented our Fiscal Year 2023 audit recommendation to ensure local counties and MA site caseworkers are appropriately trained and are held to required timelines for processing beneficiary applications, using the correct income thresholds to determine eligibility, and maintaining the required documentation to support eligibility in the case file. The Department planned to implement this recommendation by January 2025. During our audit, we performed testing related to the Department’s Medicaid eligibility internal controls in place during Fiscal Year 2025. In addition, we performed specific testing on a random nonstatistical sample of 125 beneficiaries to determine if they were properly deemed eligible for and received Medicaid benefits during Fiscal Year 2025. Our sampling methodology, including the strata and sample sizes, was developed based on our risk assessment procedures and included the following procedures: *We obtained a listing of Medicaid FFS claims that were submitted by providers and paid by the Department during Fiscal Year 2025 and a listing of capitation payments made to MCEs on behalf of Medicaid-eligible individuals during Fiscal Year 2025. The Department pulled this data from the Colorado interChange claims system. • We summarized each listing by Medicaid ID numbers (ID), and removed any IDs for which total payments and adjustments netted to $0, which can happen when the Department catches and fixes payments made in error. This resulted in two populations: (1) a population of capitation payments totaling $2,156,417,706, made on behalf of 1,398,794 individual beneficiaries, and (2) a population of FFS claims totaling $10,553,035,025, made on behalf of 1,018,911 individual beneficiaries. • We stratified our population, as shown in the following table, into six strata defined by the total amount of payments for each unique ID. As part of our analysis, we noted FFS beneficiaries represented 42 percent of the total number of individual beneficiaries who had payments made on their behalf during Fiscal Year 2025, and beneficiaries with capitation payments represented 58 percent of the total number of individual beneficiaries who had capitation payments made on their behalf during Fiscal Year 2025. Although FFS claims represented only 42 percent of the total number of individual beneficiaries, they represented 83 percent of the total dollar amount of all claims and individual capitation payments made during Fiscal Year 2025. As such, we stratified the data with two strata for capitation payments and four strata for FFS payments. We selected 26 capitation samples and 99 FFS samples from the strata for a total sample of 125 payments for beneficiaries. • For each sampled ID, we tested eligibility covering the dates of service for every Fiscal Year 2025 payment made on the beneficiary’s behalf. See " Schedule of Findings and Questioned Costs" for table/chart. Our testing included reviewing each payment’s supporting documentation, which included case files, information in CBMS data fields related to eligibility determination/redetermination, and Medicaid payment information in Colorado interChange. We performed testwork to determine whether the Department ensured that local county and MA site caseworkers obtained and maintained the required documents that supported eligibility determinations in the case files, correctly entered eligibility data into CBMS, and determined eligibility in a timely manner. What problems did the audit work identify and how were the results measured? Based on the testwork performed, we determined that the Department is still in the process of fully implementing our Fiscal Year 2023 recommendation. While we did not identify any errors related to processing beneficiary applications within the required timeframes, we continued to identify issues related to missing case file documentation and income calculations. We identified at least one error in 7 of the 125 Medicaid case files tested (6 percent). These errors resulted in a total of $240,606 in known federal and state questioned costs for Fiscal Year 2025 ($120,302 in federal costs and $120,304 in state costs). Specifically, we found the following: • Missing Case File Documentation. In three cases, we determined the case file did not have documentation to support income and/or resources, such as wage stubs or bank statements, which are necessary to support the Medicaid eligibility determination, as required by federal and state regulations. This resulted in known questioned costs of $237,745 ($118,872 in federal costs and $118,873 in state costs). Federal regulation [420 CFR 435.914] requires the Department to obtain and maintain documentation to support each beneficiary’s Medicaid eligibility determination. State regulation [10 CCR 2505-10, 8.100.4.B] notes that income may be self-attested by an applicant or member and verified through an electronic data source. If the self-attested income cannot be verified electronically, the applicant must provide documentation of income. Earned income must be verified by wage stubs, tax documents, written documentation from the employer stating the employee’s gross income, or through a telephone call to an employer. State regulation [10 CCR 2505-10, 8.100.7.A] notes that applicants receiving long-term case services under the 300% Institutionalized Special Income category must conform with the regulations regarding resource limits and exemptions set forth in section 10 CCR 2505-10, 8- 100.5, which notes that the resource limit for these long-term care individuals is $2,000. State regulation [10 CCR 2505-10, 8.100.5.M] notes that the resource limit for individuals receiving Home and Community Based Services assistance is $2,000. • Issues with Income Calculations. In four cases, we identified issues with the income calculation used to support the Medicaid eligibility determination, as required by federal and state regulations. Specifically, we found the following: III-8 [the auditor] In two cases, the incorrect number of household members was entered into CBMS, which caused the incorrect income threshold to be used in the income calculation. In addition, one of these cases also incorrectly excluded reportable income in the member’s income calculation. These issues resulted in known questioned costs of $725 ($362 in federal costs and $363 in state costs). In two cases, out-of-date income information was used in the calculation. We noted in both instances, CBMS had current income information that was not used in the income calculation. For one of those cases, if the correct income was used in the calculation, the members’ total income would have been over the eligibility limit. This resulted in known questioned costs of $2,136 ($1,068 in federal costs and $1,068 in state costs). Federal regulation [42 CFR 435.119] requires household income to be at or below 133 percent threshold of the federal poverty level. State regulation [10 CCR 2505-10, 8.100.4.G.4] notes that adults applying for medical assistance shall be determined financially eligible for medical assistance as long as their total household income does not exceed 133% of the federal poverty level. State regulation [10 CCR 2505-10, 8.100.4.C] notes that the financial eligibility of applicants for medical assistance shall be determined based on current or previous monthly household income and family size. The Modified Adjusted Gross Income calculation for the purposes of determining a household’s financial eligibility shall consist of, but is not limited to, earned income in the form of wages, salaries, and tips. Why did these problems occur? We determined that the Department’s existing internal controls over the income calculations and income and resource documentation requirements, which are necessary for Medicaid eligibility determinations, did not ensure caseworkers were determining eligibility appropriately, and in accordance with federal and state regulations. Specifically, caseworkers were not adequately trained or held accountable for ensuring that (1) the required documentation to support the income calculation was maintained within the case file, (2) current income and resource information is used when calculating monthly income and resource amounts, and (3) the correct household composition is used when determining eligibility. Why do these problems matter? As the state department responsible for ensuring that all Medicaid expenditures are appropriate, it is essential for the Department to ensure that eligibility determinations are made appropriately and in accordance with federal and state regulations. This includes ensuring that inaccurate processing of information used to determine Medicaid eligibility does not result in Medicaid benefits being provided to, and paid on behalf of, ineligible individuals, or that eligible individuals are denied benefits. Ultimately, the federal government may disallow federal funds for Medicaid program expenditures that do not adhere to regulations, and the State would be required to bear the cost of these errors. See " Schedule of Findings and Questioned Costs" for table/chart. Recommendation 2025-034 The Department of Health Care Policy and Financing should strengthen its internal controls over the income calculation and income and resource documentation requirements that are necessary for Medicaid eligibility determinations to ensure eligibility is determined appropriately and in accordance with federal and state regulations. This should include ensuring that (1) local counties and Medical Assistance site caseworkers are sufficiently trained to maintain the required documentation to support eligibility in the case file, (2) current income and resource information is used when calculating monthly income and resource amounts, and (3) the correct household composition is used when determining eligibility. Response Department of Health Care Policy and Financing Agree Implementation Date: February 2027 The Department agrees with the recommendation and will strengthen internal controls over Medicaid eligibility determinations to ensure compliance with federal and state regulations. The Department will issue formal Management Decision Letters to the identified counties requiring the development and implementation of Department-approved Corrective Action Plans. These plans will be required to address root causes related to income and resource calculation, documentation of eligibility determinations, and household composition, including any necessary training or guidance for county and Medical Assistance site caseworkers. The Department will review, approve, and monitor corrective actions to ensure deficiencies are appropriately addressed.
