Frequently Asked Questions

Per 45 C.F.R. § 75.430(i)(5), a Random Moment Time Study (RMTS) is a type of “substitute system” used for determining and documenting time spent on, and therefore the costs of, Medicaid administrative and direct service activities. Per page 108 of the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming, a RMTS is a statistically valid sampling methodology that can be used by States and LEAs to determine how much time eligible staff spend performing Medicaid reimbursable work activities. The RMTS is used to determine a statistic that is applied to salary and fringe benefits for qualified providers and reported on a cost report for direct medical services. A RMTS is generally used in an allocation of a cost pool to allowable medical, administrative (if applicable), and unallowable moments that is further allocated to Medicaid using a Medicaid Eligibility Ratio (MER). The RMTS and supporting documents become part of the documentation for the claim. The RMTS is used to determine a statistic that is applied to salary and fringe benefits for qualified providers and to other payable costs that are reported on a cost report for direct medical services.

A RMTS must reflect all of the time and activities (whether allowable or unallowable under Medicaid) performed by school employees. The RMTS sample universe (or Participant List) should include all staff who potentially perform Medicaid direct services or administrative activities. LEAs should consider both job title and job function when determining which individual staff members should be included in which cost pool.

No, while an RMTS is typically used to identify and allocate cost, it is not the only option. States also have the flexibility to utilize an alternative methodology for reimbursement and/or allocation, provided there is appropriate documentation for CMS review of the chosen methodology. Regulations on personnel expenses in 45 C.F.R. § 75.430(i) require that charges to federal awards must be based on records that reflect the actual work performed. The records must:

• be supported by a system of internal controls that provides reasonable assurance charges are accurate, allowable, and properly allocated,
• reflect the total activity for which the employee is compensated,
• encompass both federally assisted and all other activities for which the employee is compensated, and
• support the distribution of the employee's salary or wages among specific activities or cost objectives.

As stated on page 44 of the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming, if public charter schools are funded predominantly by State and local funds, including local tax revenue or appropriations, similar to other governmental entities, they may be eligible to provide the non-federal share of Medicaid or CHIP expenditures through CPEs.

However, other school entities that are not units of State or local government, including private schools, would not be considered governmental entities under 42 CF.R. § 433.51(b) and § 457.220. Direct payments to private or non-governmental educational institutions for Medicaid and CHIP SBS are available but are typically funded by State appropriations to the Medicaid/CHIP agency. Private and other non-governmental school entities may not participate directly in a CPE. However, an LEA that is a unit of government can contract with providers to provide eligible Medicaid/CHIP services to children in private entities, and CPE the contracted costs, as long as the arrangement adheres to the requirements discussed on page 43 in the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming.

In addition to a cost methodology, LEAs that are units of government may also transfer the non-federal share funds via intergovernmental transfers (IGTs) to the SMA for services provided in private schools as long as the provider receives and retains the entire Medicaid payment described in the Medicaid State plan.

CMS’ longstanding standard policy has been to recommend a 15 percent oversampling for RMTS to ensure a valid response rate of at least 85 percent or include all nonresponses as non-Medicaid and unallowable.

In general, all completed responses should be used in an RMTS. However, CMS allows for the use of an alternate methodology in cases where the TSIP specifies an oversample to ensure an adequate number of valid responses for the treatment of time study nonresponses are achieved. The alternate methodology CMS historically has approved uses an 85 percent valid response rate. CMS recommends an oversample of 15 percent to ensure an adequate number of valid responses are received and to meet the required precision level. Per page 113 of the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming, an oversample may be used only to compensate, not substitute, for the potential number of nonresponses.

If the valid response rate is above 85 percent, nonresponses may be discarded and not included in the time study results. However, if the valid response rate is below 85 percent, regardless of the 15 percent oversample, CMS has required all non-responses to be included and coded as non-Medicaid.

If medical necessity has been determined, Code 4C. Direct Medical Services – Covered on a Medical Plan of Care, Not Covered as IDEA/IEP Service is the correct code. This code should be used when district staff (employees or contracted staff) provide covered direct medical services under the SBS Program where documented on a medical plan other than an IEP/IFSP or where medical necessity has been otherwise established.
