Excellus BlueCross BlueShield · Effective Nov 20, 2025Medium impact
Chromosomal Microarray (CMA) Analysis for Prenatal Evaluation and Evaluation of Patients with Developmental Delay/ Intellectual Disability or Autism Spectrum Disorder 2.02.42
Excellus BlueCross BlueShield policy 2.02.42 covers chromosomal microarray analysis (CMA) for children with apparent nonsyndromic developmental delay or intellectual disability, autism spectrum disorder, or multiple anomalies not specific to a well-delineated genetic syndrome, and for pregnant patients undergoing invasive prenatal diagnostic testing. The 11/20/25 annual review removed the policy criteria for FMR1 gene analysis and the criterion that genetic test results have the potential to impact clinical management. The current effective date is November 20, 2025, and CMA used to confirm a disorder that is routinely diagnosed on clinical evaluation alone is considered not medically necessary.
Aetna · Identified Oct 3, 2026Medium impact
Idiopathic Scoliosis (CPB 0398, reviewed 2026-09-28)
Aetna considers spinal fusion with instrumentation and bone grafting medically necessary for idiopathic scoliosis with a curve of 40 degrees or greater in an adolescent younger than 18, or a curve of 50 degrees or greater in a young adult aged 18 to 25. Lumbar vertebral body tethering is considered medically necessary for skeletally immature members with lumbar idiopathic scoliosis whose lumbar curve is between 40 and 65 degrees, whose curve reduces by 50 percent or more on side-bending radiographs, and who have no sagittal imbalance, while vertebral body tethering for thoracic scoliosis is listed as experimental, investigational or unproven. Braces are considered medically necessary when the Boston, Charleston, Milwaukee, Providence, Rigo-Cheneau, standard TLSO and other listed types are prescribed by a qualified practitioner and furnished by a licensed or certified orthotist or prosthetist within six months of the prescription, while the Copes, SpineCor, Rosenberger, ScoliBrace, UNYQ and Whisper braces are considered experimental, investigational or unproven.
Aetna · Identified Aug 19, 2026Medium impact
Bone Mass Measurements (CPB 0134, reviewed 2026-03-19)
Aetna considers bone mass measurement medically necessary when a member meets one of the listed criteria, such as long-term glucocorticoid therapy of 5 mg prednisone or more per day for more than 3 months, long-term anticonvulsant therapy, long-term aromatase inhibitor therapy, or non-traumatic (fragility) fractures. Repeat bone mass measurements are usually not indicated more frequently than once every 2 years, except in the circumstances the policy lists. Bone mass measurement by dual photon absorptiometry, dual X-ray and laser, single photon absorptiometry, pulse-echo ultrasound, cone beam CT, deep learning-based quantitative CT, finite element analysis, skin autofluorescence for AGEs, radiofrequency echographic multi spectrometry and urinary phthalate testing is considered experimental, investigational or unproven.
Aetna · Identified Aug 18, 2026Medium impact
Musculoskeletal Assessment Systems (CPB 0212, reviewed 2026-03-25)
Aetna considers the Metrecom skeletal analysis system and other computerized, biomechanical or digital skeletal analysis systems experimental, investigational or unproven, because the value of their analysis in improving clinical outcomes is unproven, and the same applies to their individual components. The FIGUR8 Advanced Musculoskeletal Assessment System is also considered experimental, investigational or unproven for neuromuscular control screenings for injury prevention and rehabilitation, and there is a lack of peer-reviewed evidence for its clinical value. CPT codes 0778T, 95851 and 97750 are listed as not covered for the indications in the policy, as are the listed ICD-10 codes, including M00.00 through M99.9, S00.00xA through T14.91, and Z13.820 through Z13.858.
Aetna · Identified Aug 16, 2026Medium impact
Idiopathic Scoliosis (CPB 0398, reviewed 2026-01-15)
Aetna considers spinal fusion with instrumentation and bone grafting medically necessary for idiopathic scoliosis with a curve of 40 degrees or greater in an adolescent younger than 18, or a curve of 50 degrees or greater in a young adult aged 18 to 25. Lumbar vertebral body tethering is considered medically necessary for skeletally immature members with a lumbar idiopathic scoliosis curve between 40 and 65 degrees that is flexible with at least 50% reduction on side-bending radiographs and no sagittal imbalance, and the MAGEC System and Shilla growth guidance technique are considered medically necessary growing rods for members who meet the surgery criteria. The policy lists the Boston, Charleston, Milwaukee, Peak Scoliosis Bracing System, Providence, Rigo-Cheneau, Risser jacket, standard TLSO and TechnoSpine TLSO-Scoliosis Brace as medically necessary durable medical equipment, and it considers the Copes, SpineCor, ScoliBrace, UNYQ, Whisper and Rosenberger braces, the Schroth method, vertebral body stapling, ApiFix, genetic testing such as ScoliScore, and other listed methods experimental, investigational or unproven.
