Medicare cpt code - 93797, 93798 - Cardiac Rehabilitation - DX 410.00 - 410.92


Coding Requirements for Cardiac Rehabilitation Services 


The following are the applicable HCPCS codes:

93797 - Physician services for outpatient cardiac rehabilitation; without continuous ECG monitoring (per session); and

93798 - Physician services for outpatient cardiac rehabilitation; with continuous ECG monitoring (per session).

Effective for dates of service on or after January 1, 2008 and before January 1, 2010, providers and practitioners may report more than one unit of Procedure  code 93797 or 97398 for a date of service if more than one cardiac rehabilitation session lasting at least 1 hour each is provided on the same day. In order to report more than one session for a given date of service, each session must last a minimum of 60 minutes. For example, if the cardiac rehabilitation services provided on a given day total 1 hour and 50 minutes, then only one session should be billed to report the cardiac rehabilitation services provided on that day.



 Cardiac Rehabilitation Program Services Furnished On or After January 1, 2010


As specified at 42 CFR 410.49, Medicare covers cardiac rehabilitation items and services for patients who have experienced one or more of the following:

• An acute myocardial infarction within the preceding 12 months; or

• A coronary artery bypass surgery; or

• Current stable angina pectoris; or

• Heart valve repair or replacement; or

• Percutaneous transluminal coronary angioplasty (PTCA) or coronary stenting; or

• A heart or heart-lung transplant; or

• Stable, chronic heart failure defined as patients with left ventricular ejection fraction of 35% or less and New York Heart  Association (NYHA) class II to IV symptoms despite being on optimal heart failure therapy for at least 6 weeks (effective February 18, 2014).

Cardiac rehabilitation programs must include the following components:

• Physician-prescribed exercise each day cardiac rehabilitation items and services are furnished;

• Cardiac risk factor modification, including education, counseling, and behavioral intervention at least once during the program, tailored to patients’ individual needs;

• Psychosocial assessment;

• Outcomes assessment; and

• An individualized treatment plan detailing how components are utilized for each patient.



Cardiac rehabilitation items and services must be furnished in a physician’s office or a hospital outpatient setting. All settings must have a physician immediately available and accessible for medical consultations and emergencies at all times items and services are being furnished under the program. This provision is satisfied if the physician meets the requirements for the direct supervision of physician’s office services as specified at 42 CFR 410.26 and for hospital outpatient therapeutic services

Cardiac rehabilitation by national LCD is covered for only six groups of patients:
  • Patients who begin the program within 12 months of an acute Myocardial Infarction (MI).
  • Patients who have had Coronary Artery Bypass Graft (CABG) surgery.
  • Patients with stable angina pectoris.
  • Patients who have had heart valve repair/replacement.
  • Patients who have had Percutaneous Transluminal Coronary Angioplasty (PTCA) or coronary stenting.
  • Patients who have had a heart or heart-lung transplant.

Limitations
A. Facilities
Cardiac rehabilitation programs may be provided either by the outpatient department of a hospital or a physician-directed clinic. Coverage for either program is subject to the following conditions:
  • The facility meets the definition of a hospital outpatient department or a physician-directed clinic, i.e., a physician is on the premises available to perform medical duties at all times the facility is open and each patient is under the care of a hospital or clinic physician.
  • The facility has available for immediate use all the necessary cardiopulmonary emergency diagnostic and therapeutic life-saving equipment accepted by the medical community as medically necessary, e.g., oxygen, cardiopulmonary resuscitation equipment or defibrillator.
  • The program is conducted in an area set aside for the exclusive use of the program while it is in session.
  • The program is staffed by personnel necessary to conduct the program safely and effectively and who are trained in both basic and advanced life support techniques and in exercise therapy for coronary disease. When conducted in a hospital, an identified physician must be immediately available. This does not require that a physician be physically present in the exercise room itself but must be immediately available and accessible at all times in case of an emergency.
  • When conducted in the hospital, the non-physician personnel are employees of the hospital conducting the program.
  • When conducted in a clinic or physician’s office, the non-physician personnel are employees of the physician or clinic conducting the program and their services are “incident to” a physician’s professional services.
B. Diagnoses
  • For MI, the date of entry into the program must be within 12 months of the date of infarction.
  • For CABG, the initiation of the program should be early enough to have a restorative effect on the recuperative process. Therefore, the date of entry should be within six months of the CABG procedure.
  • For angina, all patients must have a pre-entry stress test that is positive for exercise-induced ischemia within six months of starting cardiac rehabilitation (see “Group II Services” below). A positive stress test in this context implies a junctional depression of 2 mm or more with associated slowly rising ST segment, or 1 mm horizontal or downsloping ST segment depressions. Over the years, nuclear perfusion studies have supplanted standard Electrocardiogram (ECG) treadmill tests as a means of evaluating ischemic heart disease, especially for patients who have abnormal rest ECGs. Therefore, the positive stress test also includes perfusion studies that demonstrate ischemia.
  • For patients with heart valve repair or replacement, the program should be early enough to provide a restorative benefit. Therefore, the date of entry must be within six months of surgery.
  • For patients who have had a PTCA or stent replacement, the program should be early enough to provide a restorative benefit. Therefore, the date of entry must be within six months of surgery.
  • Patients who have had a heart or heart-lung transplant may present special and complex posttransplant management problems. The date of entry is extended to within one year of the surgery.
C. Frequency and Duration
  • The frequency and duration of the program are generally a total of 36 sessions, two to three times per week over 12–18 weeks. Sessions extending beyond the 18 weeks may be reviewed to confirm medical necessity.
  • Services at a frequency of fewer than two sessions per week will be considered not medically necessary unless additional documentation is demonstrated verifying the patient was unable to attend due to illness or hospitalization.
  • For the purposes of this LCD, Phase II is divided into Phase IIA and Phase IIB:
    • Phase IIA is the initial outpatient cardiac rehabilitation, not to exceed a total of 36 sessions, two to three sessions per week for 12–18 weeks.
    • Phase IIB consists of an additional series of 36 sessions, two to three times per week for 12–18 weeks and will only be allowed if determined to be medically necessary. The total number of allowable sessions (Phase IIA and IIB combined) is 72 within a 36-week period. Phase IIB benefits must meet additional medical necessity criteria; specifically, there must be clear demonstration the patient is benefiting from cardiac rehabilitation and that the exit criterion below has not been met.
D. Exit Criterion
Exit criteria include, but are not restricted to, the following clinical parameters:
  • The patient has achieved a stable level of exercise tolerance without ischemia or dysrhythmia.
  • Symptoms of angina or dyspnea are stable at the patient’s maximum exercise level.
  • The patient’s resting blood pressure and heart rate are within normal limits.
  • The stress test is not positive during exercise. A positive stress test in this context implies an ECG with a junctional depression of 2 mm or more associated with slowly rising, horizontal or down-sloping ST segment.
  • For patients with valvuloplasty or valve replacement, benefits are available for Phase IIA only. Data showing that extension of the program beyond the 36 sessions is reasonable and necessary is not available.
  • The posttransplant patient poses a special challenge for the cardiac rehabilitation team. Issues such as deconditioning and cachexic deterioration may complicate the definition of a reasonable exit criterion. Based on the study of long-term cardiopulmonary exercise performed after heart transplant by Osade et al, this contractor will use a peak oxygen consumption (VO2) of greater than 90 percent predicted as the exit criterion for Phase IIA. Patients whose VO2 is less than 90 percent predicted may qualify for the additional Phase IIB.
E. Non-Covered Diagnoses
  • Use of any ICD-9-CM diagnosis code not in the “ICD-9-CM Diagnosis Codes That Support Medical Necessity” section of this LCD will be cause for denial of claims.
  • A patient with unstable angina will not qualify for cardiac rehabilitation services.
  • Congestive heart failure in the absence of other covered conditions is not included as a covered condition of cardiac rehabilitation in the CMS National Coverage Determination Manual, Publication 100-03, Section 20.10.
F. Other Services
  • Evaluation and Management (E/M) services, ECGs and other diagnostic services may be covered on the day of cardiac rehabilitation if these services are separate and distinct from the cardiac rehabilitation program and are medically necessary.
  • Forms of counseling, such as dietary counseling, psychosocial intervention, lipid management and stress management, are components of the cardiac rehabilitation program and are not separately reimbursed.
G. Definition of Group Services
  • Group I services include:
    • Continuous ECG telemetric monitoring during exercise.
    • ECG rhythm strip with interpretation and physician’s revision of exercise prescription.
    • Limited examination for physician follow-ups to adjust medication or for other treatment changes.
A visit including one or more of the Group I services is considered as one routine cardiac rehabilitation visit. For the visit to be reimbursable, at least one of the Group I services must be performed. The same rate of reimbursement would be allowed for each visit, but not all services need to be performed at each visit.
  • Group II services include:
    • New patient comprehensive evaluation, including history, physical and preparation of initial exercise prescription. One will be allowed at the beginning of the program if not already performed by the patient’s attending physician or if that performed by the patient’s physician is not acceptable to the program’s director.
    • ECG stress test (treadmill or bicycle ergometer) with physician monitoring and report. One will be allowed at the beginning of the program and one after three months (usually the completion of the program).
    • Other physician services, as needed.
For requirements on physical medicine and rehabilitation modalities and procedures, see TrailBlazer’s LCD Therapy Services (PT, OT, SLP) – 4Y-26AB.”

 Contractors shall consider a service to be reasonable and necessary if the contractor determines that the service is:
  • Safe and effective.
  • Not experimental or investigational (exception: routine costs of qualifying clinical trial services with dates of service on or after September 19, 2000, which meet the requirements of the clinical trials NCD are considered reasonable and necessary).
  • Appropriate, including the duration and frequency that is considered appropriate for the service, in terms of whether it is:
    • Furnished in accordance with accepted standards of medical practice for the diagnosis or treatment of the patient’s condition or to improve the function of a malformed body member.
    • Furnished in a setting appropriate to the patient’s medical needs and condition.
    • Ordered and furnished by qualified personnel.
    • One that meets, but does not exceed, the patient’s medical need.
    • At least as beneficial as an existing and available medically appropriate alternative.
Bill Type Codes
Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.
13X, 85X
Revenue Codes
Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

CPT/HCPCS Codes
Note:
Providers are reminded to refer to the long descriptors of the CPT codes in their CPT books. The American Medical Association (AMA) and the Centers for Medicare & Medicaid Services (CMS) require the use of shortCPT descriptors in policies published on the Web.

Cardiac rehab
93798©
Cardiac rehab/monitor

Effective for dates of service on or after January 1, 2010, hospitals and practitioners may report a maximum of 2 1-hour sessions per day. In order to report one session of cardiac rehabilitation services in a day, the duration of treatment must be at least 31 minutes. Two sessions of cardiac rehabilitation services may only be reported in the same day if the duration of treatment is at least 91 minutes. In other words, the first session would account for 60 minutes and the second session would account for at least 31 minutes if two sessions are reported. If several shorter periods of cardiac rehabilitation services are furnished on a given day, the minutes of service during those periods must be added together for reporting in 1-hour session increments.


Example: If the patient receives 20 minutes of cardiac rehabilitation services in the day, no cardiac rehabilitation session may be reported because less than 31 minutes of services were furnished.

Example: If a patient receives 20 minutes of cardiac rehabilitation services in the morning and 35 minutes of cardiac rehabilitation services in the afternoon of a single day, the hospital or practitioner would report 1 session of cardiac rehabilitation services under 1 unit of the appropriate Procedure  code for the total duration of 55 minutes of cardiac rehabilitation services on that day.

Example: If the patient receives 70 minutes of cardiac rehabilitation services in the morning and 25 minutes of cardiac rehabilitation services in the afternoon of a single day, the hospital or practitioner would report two sessions of cardiac rehabilitation services under the appropriate Procedure  code(s) because the total duration of cardiac rehabilitation services on that day of 95 minutes exceeds 90 minutes.

Example: If the patient receives 70 minutes of cardiac rehabilitation services in the morning and 85 minutes of cardiac rehabilitation services in the afternoon of a single day, the hospital or practitioner would report two sessions of cardiac rehabilitation services under the appropriate Procedure  code(s) for the total duration of cardiac rehabilitation services of 155 minutes. A maximum of two sessions per day may be reported, regardless of the total duration of cardiac rehabilitation services.


ICD-9-CM Codes That Support Medical Necessity
The CPT/HCPCS codes included in this LCD will be subjected to procedure to diagnosis editing. The following lists include only those diagnoses for which the identified CPT/HCPCS procedures are covered. If a covered diagnosis is not on the claim, the edit will automatically deny the service as not medically necessary.
Medicare is establishing the following limited coverage for CPT/HCPCS codes 93797 and 93798:
Covered for:
410.00–410.02
Acute myocardial infarction of anterolateral wall

Note: Providers should continue to submit ICD-9-CM diagnosis codes without decimals on their claim forms and electronic claims.

Documentation Requirements
Documentation supporting medical necessity should be legible, maintained in the patient’s medical record and made available to Medicare upon request.
ICD-9-CM diagnosis codes supporting medical necessity must be submitted with each claim. Claims submitted without such evidence will be denied as not medically necessary.
Any diagnosis submitted must have documentation in the patient’s record to support coverage and medical necessity.
All cardiac rehabilitation providers must have documentation of the qualifying event in the patient’s medical record. This information may include copies of the referring physician’s records or reports. A prescription for cardiac rehabilitation from the referring physician must be maintained in the patient’s medical record by the provider of the cardiac rehabilitation service.
When billing CPT code 93798, the documentation must clearly indicate the patient is receiving continuous ECG monitoring.
A cardiac rehabilitation record must be maintained. All components, including ECG strips, must be maintained. All components of the service (medical assessment, ECG monitoring, smoking cessation, dietary counseling and psychological counseling) must be assessed and provided, where appropriate. It is not expected that every component is provided at each session but the total Phase II (A and B) record must reflect those benefits.
A record must be kept indicating the identity of the supervising physician and the identity of the physician who will respond immediately should an adverse consequence develop. This record must be made available to Medicare upon request.

Utilization Guidelines
Refer to “Indications and Limitations of Coverage and/or Medical Necessity,” Section C, “Frequency and Duration” above.
Notice: This LCD imposes utilization guideline limitations. Despite Medicare’s allowing up to these maximums, each patient’s condition and response to treatment must medically warrant the number of services reported for payment. Medicare requires the medical necessity for each service reported to be clearly demonstrated in the patient’s medical record. Medicare expects that patients will not routinely require the maximum allowable number of services.
