CMS Pub. 100-02, ch. 2, § 30.2.2.1

In the context of IPF services, emphasis is placed on the presence of active treatment and,

therefore, this determination is the crucial one. Simply applying the skilled care

definition for general hospitals is not sufficient for determining whether payment may be

made since that definition does not take into account the patient's potential for

improvement nor was it designed to permit the more sophisticated judgments required by

the concept of active treatment. For services in an IPF to be designated as active

treatment, they must be:

• Provided under an individualized treatment or diagnostic plan;

• Reasonably expected to improve the patient's condition or for the purpose of

diagnosis; and

• Supervised and evaluated by a physician.

Such factors as diagnosis, length of hospitalization, and the degree of functional

limitation, while useful as general indicators of the kind of care most likely being

furnished in a given situation, are not controlling in deciding whether the care was active

treatment. Refer to 42 CFR 482.61, Conditions of Participation for Hospitals, for a full

description of what constitutes active treatment.

The period of time covered by the physician's certification is referred to as a period of

active treatment. This period should include all days on which inpatient psychiatric

facility services were provided because of the individual's need for active treatment (not

just the days on which specific therapeutic or diagnostic services are rendered). For

example, a patient's program of treatment may necessitate the discontinuance of therapy

for a period of time or it may include a period of observation, either in preparation for or

as a follow-up to therapy, while only maintenance or protective services are furnished. If

such periods were essential to the overall treatment plan, they would be regarded as part

of the period of active treatment.

The fact that a patient is under the supervision of a physician does not necessarily mean

the patient is getting active treatment. For example, medical supervision of a patient may

be necessary to assure the early detection of significant changes in his/her condition;

however, in the absence of a specific program of therapy designed to effect improvement,

a finding that the patient is receiving active treatment would be precluded.

The program's definition of active treatment does not automatically exclude from

coverage services rendered to patients who have conditions that ordinarily result in

progressive physical and/or mental deterioration. Although patients with such diagnosis

will most commonly be receiving custodial care, they may also receive services that meet

the program's definition of active treatment (e.g., where a patient with Alzheimer's

disease or Pick's disease received services designed to alleviate the effects of paralysis,

epileptic seizures, or some other neurological symptom, or where a patient in the terminal

stages of any disease received life-supportive care). A period of hospitalization during

which services of this kind were furnished would be regarded as a period of active

treatment.
