Titanium Rib (CPB 0582, reviewed 2026-09-02)
Aetna's Clinical Policy Bulletin 0582 considers the vertical expandable prosthetic titanium rib (VEPTR) medically necessary for treatment of thoracic insufficiency syndrome in skeletally immature persons. Aetna considers VEPTR experimental, investigational or unproven for scoliosis without thoracic insufficiency syndrome, including congenital scoliosis, early onset scoliosis, idiopathic infantile scoliosis, kyphoscoliosis, and scoliosis associated with spinal muscular atrophy, and for all other indications such as chest wall repair in Poland syndrome and hyper-kyphosis. The policy lists no specific CPT or HCPCS code for VEPTR, and it lists ICD-10 codes as covered only when the selection criteria are met and the condition results in thoracic insufficiency syndrome.

Total Body Plethysmography (CPB 0474, reviewed 2026-07-17)
Aetna's Clinical Policy Bulletin 0474 covers total body plethysmography as an adjunct to complete pulmonary function testing, including residual volumes and diffusion, for these indications: determining bronchial hyper-reactivity in response to methacholine, histamine, or isocapnic hyperventilation; determining response to bronchodilators in persons who show a clinical response but no FEV1 improvement by spirometry; evaluating obstructive lung diseases such as bullous emphysema and cystic fibrosis; evaluating airflow resistance in obstructive processes where plethysmography is needed for accurate true lung volumes; measuring lung volumes to distinguish restrictive from obstructive processes when vital capacity is below 80% predicted on spirometry; and measuring lung volumes when multiple repeated trials are required or the subject cannot perform multi-breath tests. The policy considers total body plethysmography experimental, investigational, or unproven for all other indications, including screening asymptomatic persons with chronic obstructive pulmonary disease, pectus excavatum, primary pulmonary hypertension, monitoring bleomycin toxicity, scoliosis, and systemic sclerosis.

Titanium Rib (CPB 0582, reviewed 2025-12-02)
Aetna's Clinical Policy Bulletin 0582 considers the vertical expandable prosthetic titanium rib (VEPTR) medically necessary for treating thoracic insufficiency syndrome in skeletally immature persons. The policy notes that thoracic insufficiency syndrome may include flail chest syndrome, hypoplastic thorax syndrome (such as achondroplasia, Ellis van Creveld syndrome, Jarcho-Levin syndrome and Jeune's syndrome), and rib fusion and scoliosis. Aetna considers VEPTR experimental, investigational, or unproven for scoliosis without thoracic insufficiency syndrome, including congenital scoliosis, early onset scoliosis, idiopathic infantile scoliosis, kyphoscoliosis, and scoliosis associated with spinal muscular atrophy, and for all other indications such as chest wall repair in Poland syndrome and hyper-kyphosis. The policy states there is no specific CPT or HCPCS code for VEPTR, and lists ICD-10 codes that are covered only when they result in thoracic insufficiency syndrome.

Surface Scanning and Macro Electromyography (CPB 0112, reviewed 2026-03-25)
Aetna Clinical Policy Bulletin 0112, last reviewed 03/25/2026, considers high-density surface EMG, surface scanning EMG, paraspinal surface EMG and macro EMG experimental, investigational, or unproven as a diagnostic test for low back pain and other thoracolumbar segmental abnormalities, and for all other indications. It also considers surface EMG devices for diagnosis and/or monitoring of nocturnal bruxism experimental, and lists the Neurophysiologic Pain Profile (NPP), the spine matrix (lumbar matrix) scan and Spinoscopy under the same experimental designation. The bulletin states that surface scanning EMG should not be confused with conventional needle EMG or with surface electrodes used in EMG biofeedback, which it considers medically necessary for appropriate indications.
Aetna · Identified Aug 13, 2026Medium impact
Pedobarography (CPB 0294, reviewed 2026-04-17)
Aetna considers pedobarography (foot pressure studies) experimental, investigational, or unproven, because the medical literature does not contain reliable evidence that it improves diagnosis and management of foot conditions or health outcomes. CPT 96001, comprehensive computer-based motion analysis with dynamic plantar pressure measurements during walking, is listed as not covered for the indications in this policy. Related CPT codes include motion analysis, surface electromyography and physician interpretation, related HCPCS codes include ankle-foot orthoses and orthopedic shoes, and ICD-10 codes for diabetes with neurological complications, pressure ulcers of the ankle and heel, and osteoarthritis of the ankle and foot are listed as not covered for these indications.
Blue Cross & Blue Shield of Mississippi · Identified Jun 20, 2026Medium impact
Vertical Expandable Prosthetic Titanium Rib
Use of the vertical expandable prosthetic titanium rib is considered medically necessary in the treatment of progressive thoracic insufficiency syndrome due to rib and/or chest wall defects in infants and children between 6 months of age and skeletal maturity. Use of the device for all other conditions, including scoliosis in individuals without thoracic insufficiency, is considered investigational. Due to the complexity of thoracoplasty and the young age of the individuals, implantation should be performed in specialized centers.
Aetna · Identified Aug 15, 2026Low impact
Extracorporeal Shock-Wave Therapy for Musculoskeletal Indications and Soft Tissue Injuries (CPB 0649, reviewed 2025-10-02)
This is Aetna Clinical Policy Bulletin 0649, reviewed October 2, 2025 and first found by PolicyChanges in August 2026, so it is historical material and the current version should be confirmed before acting. Aetna covers extracorporeal shock-wave therapy only for calcific tendinopathy of the shoulder with a calcium deposit of at least 1 cm lasting 6 months or more after conservative care has failed, and lists dozens of other musculoskeletal, wound and medical uses as experimental, investigational or unproven.
