Indications and Limitations of Coverage

 

Inpatient Hospital Stay for Alcohol Detoxification

• Many hospitals provide detoxification services during the more acute stages of alcoholism or alcohol withdrawal.

• When the high probability or occurrence of medical complications (e.g., delirium, confusion, trauma, or unconsciousness) during detoxification for acute alcoholism or alcohol withdrawal necessitates the constant availability of physicians and/or complex medical equipment found only in the hospital setting, inpatient hospital care during this period is considered reasonable and necessary and is therefore covered under the program.

• Generally, detoxification can be accomplished within 2-3 days with an occasional need for up to 5 days where the patient's condition dictates.

• This limit (5 days) may be extended in an individual case where there is a need for a longer period for detoxification for a particular patient.

• In such cases, however, there should be documentation by a physician which substantiates that a longer period of detoxification was reasonable and necessary.

• When the detoxification needs of an individual no longer require an inpatient hospital setting, coverage should be denied on the basis that inpatient hospital care is not reasonable and necessary as required by section 1862(a)(1) of the Act.

• Following detoxification a patient may be transferred to an inpatient rehabilitation unit or discharged to a residential treatment program or outpatient treatment setting.

 

Inpatient Hospital Stay for Alcohol Rehabilitation

• Hospitals may also provide structured inpatient alcohol rehabilitation programs to the chronic alcoholic.

• These programs are composed primarily of coordinated educational and psychotherapeutic services provided on a group basis.

• Depending on the subject matter, a series of lectures, discussions, films, and group therapy sessions are led by either physicians, psychologists, or alcoholism counselors from the hospital or various outside organizations.

• In addition, individual psychotherapy and family counseling (see §70.1 of the NCD Manual) may be provided in selected cases.

o These programs are conducted under the supervision and direction of a physician.

o Patients may directly enter an inpatient hospital rehabilitation program after having undergone detoxification in the same hospital or in another hospital or may enter an inpatient hospital rehabilitation program without prior hospitalization for detoxification.

• Alcohol rehabilitation can be provided in a variety of settings other than the hospital setting.

o In order for an inpatient hospital stay for alcohol rehabilitation to be covered under Medicare it must be medically necessary for the care to be provided in the inpatient hospital setting rather than in a less costly facility or on an outpatient basis.

o Inpatient hospital care for receipt of an alcohol rehabilitation program would generally be medically necessary where either

 (1) There is documentation by the physician that recent alcohol rehabilitation services in a less intensive setting or on an outpatient basis have proven unsuccessful and, as a consequence, the patient requires the supervision and intensity of services which can only be found in the controlled environment of the hospital.

Or

 (2) Only the hospital environment can assure the medical management or control of the patient's concomitant conditions during the course of alcohol rehabilitation. (However, a patient's concomitant condition may make the use of certain alcohol treatment modalities medically inappropriate.)

o In addition, the "active treatment" criteria (see the Medicare Benefit Policy Manual, Chapter 2, "Inpatient Psychiatric Hospital Services," §20) should be applied to psychiatric care in the general hospital as well as to psychiatric care in a psychiatric hospital.

o Since alcoholism is classifiable as a psychiatric condition the "active treatment" criteria must also be met in order for alcohol rehabilitation services to be covered under Medicare. (Thus, it is the combined need for "active treatment" and for covered care which can only be provided in the inpatient hospital setting, rather than the fact that rehabilitation immediately follows a period of detoxification, which provides the basis for coverage of inpatient hospital alcohol rehabilitation programs.)

• Generally 16-19 days of rehabilitation services are sufficient to bring a patient to a point where care could be continued in other than an inpatient hospital setting.

o An inpatient hospital stay for alcohol rehabilitation may be extended beyond this limit in an individual case where a longer period of alcohol rehabilitation is medically necessary.

o In such cases, however, there should be documentation by a physician which substantiates the need for such care.

o Where the rehabilitation needs of an individual no longer require an inpatient hospital setting, coverage should be denied on the basis that inpatient hospital care is not reasonable and necessary as required by section 1862(a)(1) of the Act.

• Subsequent admissions to the inpatient hospital setting for alcohol rehabilitation follow-up, reinforcement, or "recap" treatments are considered to be readmissions (rather than an extension of the original stay) and must meet the requirements of this section for coverage under Medicare.

o Prior admissions to the inpatient hospital setting either in the same hospital or in a different hospital may be an indication that the "active treatment" requirements are not met (i.e., there is no reasonable expectation of improvement) and the stay should not be covered.

o Accordingly, there should be documentation to establish that "readmission" to the hospital setting for alcohol rehabilitation services can reasonably be expected to result in improvement of the patient's condition.

o For example, the documentation should indicate what changes in the patient's medical condition, social or emotional status, or treatment plan make improvement likely, or why the patient's initial hospital treatment was not sufficient.

 

Combined Alcohol Detoxification/Rehabilitation Programs

• Fiscal intermediaries should apply the guidelines in A. and B. above to both phases of a combined inpatient hospital alcohol detoxification/rehabilitation program.

o Not all patients who require the inpatient hospital setting for detoxification also need the inpatient hospital setting for rehabilitation. (See §130.1 of the NCD Manual for coverage of outpatient hospital alcohol rehabilitation services.)

o Where the inpatient hospital setting is medically necessary for both alcohol detoxification and rehabilitation, generally a 3-week period is reasonable and necessary to bring the patient to the point where care can be continued in other than an inpatient hospital setting.

• Decisions regarding reasonableness and necessity of treatment, the need for an inpatient hospital level of care, and length of treatment should be made by intermediaries based on accepted medical practice with the advice of their medical consultant. (In hospitals under PSRO review, PSRO determinations of medical necessity of services and appropriateness of the level of care at which services are provided are binding on the title XVIII fiscal intermediaries for purposes of adjudicating claims for payment.)
