Aetna Pulmonary Rehabilitation coverage criteria

Aetna CPB 0032 covers medically supervised outpatient pulmonary rehabilitation (typically up to 6 weeks or 36 hours) for members with a qualifying chronic pulmonary or pulmonary-function-affecting condition who meet all entry criteria - dyspnea, reduced exercise tolerance limiting ADLs/work, persistent symptoms despite medical management, objective moderate-to-severe functional impairment (VO2max <=20 ml/kg/min or FEV1/FVC/Dlco <60% predicted), willingness/ability to participate, and no disqualifying comorbidities; it is also covered for lung transplant candidates. It is not medically necessary for very severe (housebound/bed-bound) impairment, for repeat programs (except with lung transplant or lung volume reduction surgery), or once the member plateaus/cannot sustain or improve gains, and is experimental/investigational for all other indications.

When does Aetna cover Pulmonary Rehabilitation (CPT 94625), and what gets it denied?

Path
Aetna CPB 0032 covers medically supervised outpatient pulmonary rehabilitation (typically up to 6 weeks or 36 hours) for members with a qualifying chronic pulmonary or pulmonary-function-affecting condition who meet all entry criteria - dyspnea, reduced exercise tolerance limiting ADLs/work, persistent symptoms despite medical management, objective moderate-to-severe functional impairment (VO2max <=20 ml/kg/min or FEV1/FVC/Dlco <60% predicted), willingness/ability to participate, and no disqualifying comorbidities; it is also covered for lung transplant candidates. It is not medically necessary for very severe (housebound/bed-bound) impairment, for repeat programs (except with lung transplant or lung volume reduction surgery), or once the member plateaus/cannot sustain or improve gains, and is experimental/investigational for all other indications. Coverage criteria include: Entry into a medically supervised outpatient pulmonary rehabilitation program is covered when ALL of the following are met (criteria 1-7 below).; Underlying condition (criterion 1 of entry - meet this AND all others): Member has chronic pulmonary disease including alpha-1 antitrypsin deficiency, asbestosis, asthma, emphysema, chronic airflow obstruction, chronic bronchitis, cystic fibrosis, fibrosing alveolitis, pneumoconiosis, pulmonary alveolar proteinosis, pulmonary fibrosis, pulmonary hemosiderosis, persistent pulmonary impairment from COVID-19, radiation pneumonitis; OR a condition affecting pulmonary function such as ankylosing spondylitis, bronchopulmonary dysplasia, Guillain-Barre syndrome, lung cancer, muscular dystrophy, myasthenia gravis, paralysis of diaphragm, sarcoidosis, or scoliosis.; Dyspnea (criterion 2 of entry): Member has dyspnea at rest or with exertion.; Exercise limitation (criterion 3 of entry): Member has a reduction in exercise tolerance that restricts the ability to perform activities of daily living and/or work.; Medical management (criterion 4 of entry): Symptoms persist despite appropriate medical management.; Moderate-to-severe functional pulmonary disability (criterion 5 of entry - evidenced by ONE of): (a) a maximal pulmonary exercise stress test under optimal bronchodilatory treatment which demonstrates a respiratory limitation to exercise with a maximal oxygen uptake (VO2max) equal to or less than 20 ml/kg/min, or about 5 metabolic equivalents (METS); OR (b) pulmonary function tests showing that either the forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, or diffusion capacity for carbon monoxide (Dlco) is less than 60% of that predicted.; Patient capability (criterion 6 of entry): Member is physically able, motivated and willing to participate in the pulmonary rehabilitation program and be a candidate for self-care post program.; No contraindicated comorbidities (criterion 7 of entry): Member does not have any concomitant medical condition that would otherwise imminently contribute to deterioration of pulmonary status or undermine the expected benefits of the program (e.g., symptomatic coronary artery disease, congestive heart failure, myocardial infarction within the last 6 months, dysrhythmia, active joint disease, claudication, malignancy).; Lung transplant candidates: Pulmonary rehabilitation is medically necessary for persons receiving a medically necessary lung transplantation. For lung transplant candidates, pulmonary rehabilitation typically begins when the member is listed for transplant, and continues for 6 weeks after transplantation, at which time the member is transitioned to a home exercise program.; Program duration: A typical course of pulmonary rehabilitation extends for up to 6 weeks or 36 hours of therapy.; Repeat programs: Repeat pulmonary rehabilitation programs are considered not medically necessary, EXCEPT for patients undergoing a repeat pulmonary rehabilitation program in connection with lung transplantation or lung volume reduction surgery.; Continuation beyond the initial course may be considered medically necessary with documentation of ALL of: progress in the initial 6 weeks or 36 hours of pulmonary rehabilitation; documentation that the patient's performance capacity is expected to improve; and assessment indicating that continuation of the supervised exercise training is necessary to enable the patient to reach an acceptable level of individual exercise tolerance.. Applies to 5 codes: 94625, 94626, G0237, G0238, G0239.
Action
Confirm prior-authorization status with Aetna before scheduling — it is code- and plan-specific, and this policy is not an exact authorization source. Documentation: A dated description of treatment received for each scheduled visit.; Periodic (usually at least every 5 visits) exercise testing demonstrating objective measurable findings of physical and functional status showing improvement from baseline assessments to substantiate progress achieved.; Periodic (usually at least every 5 visits) assessment with revision and/or re-statement of short-term goals and treatment plan.; Periodic (usually bi-weekly) team conference notes of individual goals and progress.; A treatment plan to attain goals with justification for continuing rehabilitation program, including frequency and duration.; Evidence of communication with referring physician.; Initial pulmonary rehabilitation assessment including: diagnostic work-up and rehabilitation potential evaluation; detailed description of specific ADL problems; chest X-ray or report review; pulmonary function testing; exercise testing assessing oxygen consumption and oxygenation at rest and with exercise; demonstration of high motivation; determination of appropriate care type; goal and objective setting; and outcome anticipation.
Trap
Policy exclusions and limitations: Experimental, investigational, or unproven: Aetna considers pulmonary rehabilitation experimental, investigational, or unproven for all other indications (except for the ones listed above as medically necessary).; Very severe pulmonary impairment (not an appropriate candidate / not medically necessary): Pulmonary rehabilitation is not considered medically necessary in persons who have very severe pulmonary impairment as evidenced by dyspnea at rest, difficulty in conversation (one-word answers), inability to work, cessation of most or all usual activities making them housebound and often limiting them to bed or chair with dependency upon assistance from others for most ADL.; Not medically necessary - repetitive services for chronic baseline conditions.; Not medically necessary - when there is an inability to sustain gains.; Not medically necessary - when there is a plateau in patient's progress toward goals, such that there is minimal or no potential for further substantial progress.; Not medically necessary - when there is no overall improvement.; Exercise equipment: Most Aetna plans exclude coverage of exercise equipment (check benefit plan descriptions for details). Itemized charges for the use, rental, or purchase of exercise equipment may not be covered expenses; this includes any charges for fitness center or health club memberships.; Contraindication - nicotine dependence (recent or has quit for less than 3 months).; Contraindication - ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction within last 6 months.; Contraindication - chronic ischemic heart disease (symptomatic) / symptomatic coronary artery disease.; Contraindication - paroxysmal tachycardia, atrial fibrillation and flutter, and other cardiac arrhythmias (dysrhythmia).; Contraindication - heart failure (congestive heart failure).; Contraindication - peripheral vascular disease and venous embolism/thrombosis (claudication).; Contraindication - malignant neoplasm (not covered for pre-operative pulmonary rehabilitation, except lung cancer).; Contraindication - arthropathies (active joint disease). Claims may be denied when the requested service falls under these. Some of these are conditional (note the stated exceptions) — confirm specifics against the bulletin.
