They help doctors and researchers find better ways to prevent, diagnose, or treat diseases. Clinical trials test new types of medical care, like how well a new cancer drug works. The trials help doctors and researchers see if the new care works and if it is safe. They may also be used to compare different treatments for the same condition to see which treatment is better, or to test new uses for treatments already in use.

CMS AGENT

Any individual or organization, public or private, with whom CMS has a contractual arrangement to contribute to or participate in the Medicare survey and certification process. The State survey agency is the most common example of a "CMS" agent as established through the partnership role of the State agency (SA) plays in the survey process under the provisions of �1864 of the Act. A private physician serving a contractual consultant role with the SA or CMS regional office as part of a survey and certification activity is another example of a "CMS agent".

This is usually 24 months after the effective data of the associated final rule for most entities, but 36 months after the effective data for small health plans. For future changes in the standards, the compliance date would be at least 180 days after the effective data, but can be longer for small health plans and for complex changes.

CONTINGENCY MARGIN

An amount included in the actuarial rates to provide for changes in the contingency level in the trust fund. Positive margins increase the contingency level, and negative margins decrease it.

CONTINUATION OF ENROLLMENT

Allows MCOs to offer enrollees the option of continued enrollment in the M+C plan when enrollees leave the plan?s service area to reside elsewhere. CMS has interpreted this to be on a permanent basis. M+C Organizations that choose the continuation of enrollment option must explain it in marketing materials and make it available to all enrollees in the service area. Enrollees may choose to exercise this option when they move or they may choose to disenroll.

CONTINUING CARE RETIREMENT COMMUNITY (CCRC)

A housing community that provides different levels of care based on what each resident needs over time. This is sometimes called "life care" and can range from independent living in an apartment to assisted living to full-time care in a nursing home. Residents move from one setting to another based on their needs but continue to live as part of the community. Care in CCRCs is usually expensive. Generally, CCRCs require a large payment before you move in and charge monthly fees.

See 42 C.F.R. � 422.4(a)(1).

COORDINATION OF BENEFITS

Process for determining the respective responsibilities of two or more health plans that have some financial responsibility for a medical claim. Also called cross-over.

COORDINATION PERIOD

COST RATE

The ratio of the cost (or outgo, expenditures, or disbursements) of the program on an incurred basis during a given year to the taxable payroll for the year. In this context, the outgo is defined to exclude benefit payments and administrative costs for those uninsured persons for whom payments are reimbursed from the general fund of the Treasury, and for voluntary enrollees, who pay a premium to be enrolled.

COST REPORT

The report required from providers on an annual basis in order to make a proper determination of amounts payable under the Medicare program.

COST SHARING

COST-BASED HEALTH MAINTENANCE ORGANIZATION

A type of managed care organization that will pay for all of the enrollees/members' medical care costs in return for a monthly premium, plus any applicable deductible or co-payment. The HMO will pay for all hospital costs (generally referred to as Part A) and physician costs (generally referred to as Part B) that it has arranged for and ordered. Like a health care prepayment plan (HCPP), except for out-of-area emergency services, if a Medicare member/enrollee chooses to obtain services that have not been arranged for by the HMO, he/she is liable for any applicable deductible and co-insurance amounts, with the balance to be paid by the regional Medicare intermediary and/or carrier.

COVERAGE ANALYSIS FOR LABORATORIES (CALS)

CALs is an abbreviated process, similar to the NCD process, for making changes to the coding component of the negotiated laboratory NCDs. The process is used for adjusting the list of covered (or non-covered) ICD-9-CM diagnosis codes and coding guidance in the NCDs when there is a question regarding whether the code flows from the narrative indications in the NCD. A tracking sheet is posted opening a CAL and a 30-day public comment period follows. A decision memorandum announcing and explaining the decision is posted following the comment period. Changes are implemented in the next available quarterly update of the laboratory edit module. More details regarding the process can be found in 68 FR 74607.

COVERAGE BASIS

The M+C Plan charge schedule used to base the maximum dollar coverage or coinsurance level for a service category (e.g., a $500 annual coverage limit for a prescription drug benefit may be based on a Published Retailed Price schedule, or 20% coinsurance for DME benefit may be based on a Medicare FFS fee schedule).

COVERAGE ISSUES MANUAL (CIM)

The CIM has been replaced by the Medicare National Coverage Determinations Manual.

However, effective July 1991, coverage is mandatory for State and local employees who are not participating in a public employee retirement system. All new State and local employees have been covered since April 1986. In a few situations-for instance, ministers or self-employed members of certain religious groups-workers can opt out of coverage. Covered employment for HI includes all federal employees (whereas covered employment for OASDI includes some, but not all, federal employees).

COVERED ENTITY

Under HIPAA, this is a health plan, a health care clearinghouse, or a health care provider who transmits any health information in electronic form in connection with a HIPAA transaction.

COVERED FUNCTION

Functions that make an entity a health plan, a health care provider, or a health care clearinghouse.

COVERED SERVICES

Services for which SMI pays, as defined and limited by statute. Covered services include most physician services, care in outpatient departments of hospitals, diagnostic tests, DME, ambulance services, and other health services that are not covered by the HI program.

COVERED WORKER

A person who has earnings creditable for Social Security purposes on the basis of services for wages in covered employment and/or on the basis of income from covered self-employment. The number of HI covered workers is slightly larger than the number of OASDI covered workers because of different coverage status for federal employment. See "Covered employment."

CREDITABLE COVERAGE

Any previous health insurance coverage that can be used to shorten the pre-existing condition waiting period. (See Pre-existing Conditions.)

CRITERIA

The expected levels of achievement or specifications against which performance can be assessed.

CRITICAL ACCESS HOSPITAL

A small facility that gives limited outpatient and inpatient hospital services to people in rural areas.

CROSSWALKING

A new test is determined to be similar to an existing test, multiple existing test codes, or a portion of an existing test code. The new test code is then assigned the related existing local fee schedule amounts and resulting national limitation amount. In some instances, a test may only equate to a portion of a test, and, in those instances, payment at an appropriate percentage of the payment for the existing test is assigned.

CURRENT DENTAL TERMINOLOGY

A medical code set of dental procedures, maintained and copyrighted by the American Dental Association (ADA), and adopted by the Secretary of HHS as the standard for reporting dental services on standard transactions.

CURRENT PROCEDURAL TERMINOLOGY

A medical code set of physician and other services, maintained and copyrighted by the American Medical Association (AMA), and adopted by the Secretary of HHS as the standard for reporting physician and other services on standard transactions.

CUSTODIAL CARE

Nonskilled, personal care, such as help with activities of daily living like bathing, dressing, eating, getting in or out of a bed or chair, moving round, and using the bathroom. It may also include care that most people do themselves, like using eye drops. In most cases, Medicare doesn?t pay for custodial care.

CUSTODIAL CARE FACILITY

A facility, which provides room, board, and other personal assistance services, generally on a long-term basis and which does not include a medical component.

CUSTODIAN

The person responsible for the security and safeguard of CMS data for the duration of the project.
