Arkansas Medicaid is expanding coverage for blood pressure monitors and cuffs for eligible members with high-risk pregnancies and/or in the postpartum period, effective September 1, 2026. Two new HCPCS codes (A4663 and A4670) are now covered under the MEDSP contract at specified rates, with a limit of one monitor and one cuff per nine-month period.
Aetna considers validated home blood pressure monitors medically necessary as an alternative to ambulatory blood pressure monitoring to confirm hypertension in members age 18 and older with office readings greater than 140 systolic or 90 diastolic. Validated blood pressure monitors are considered medically necessary for members receiving hemodialysis or peritoneal dialysis in the home, and validated blood pressure cuffs are considered medically necessary durable medical equipment for members with hypertension. Self-contained pacemaker monitors, including audible and visible signal monitors, digital electronic monitors, and a specialized telephone attachment for trans-telephonic transmission of results, are considered medically necessary for members with cardiac pacemakers. Automated oscillometer serial blood pressure monitors for home use, AngelMed Guardian, CardioMEMS pillow and components, home and implantable congestive heart failure monitors, implantable inferior vena cava sensors, implantable wireless pulmonary artery pressure monitors for heart failure, Zoll Heart Failure and Arrhythmia Management System, bioelectrical impedance analysis, and non-invasive central blood pressure assessment with SphygmoCor are considered experimental, investigational, or unproven. Pulse tachometers do not meet Aetna's definition of covered durable medical equipment.
Aetna's dialysis policy (CPB 0541), last reviewed 08/26/2026, considers hemodialysis or intermittent peritoneal dialysis up to 3 times per week medically necessary for renal failure. More frequent dialysis is considered medically necessary when hyperkalemia, hypophosphatemia, pregnancy, fluid overload, acute pericarditis, congestive heart failure, pulmonary edema or severe catabolic state is refractory to dialysis 3 times per week. Home hemodialysis equipment, supplies and skilled nursing visits are considered medically necessary when prescribed by a physician for members with end stage renal disease, and the equipment is usually rented during the first 30 months of hemodialysis.
Aetna considers validated home blood pressure monitors medically necessary as an alternative to ambulatory blood pressure monitoring to confirm hypertension in members age 18 and older with office readings greater than 140 systolic or 90 diastolic, when the cuff is prescribed by a physician, is an arm device, has the correct cuff size assessed and provided by the vendor, and only one cuff per 5 years is considered medically necessary. Validated blood pressure monitors are also considered medically necessary for members receiving hemodialysis or peritoneal dialysis in the home, and self-contained pacemaker monitors are considered medically necessary for members with cardiac pacemakers. Pulse tachometers do not meet Aetna's definition of covered DME, and the following are considered experimental, investigational, or unproven: AngelMed Guardian, automated oscillometer serial blood pressure monitors for home use, bioelectrical impedance analysis, CardioMEMS, home congestive heart failure telemonitoring devices, implantable congestive heart failure monitors, the implantable inferior vena cava sensor, non-invasive central blood pressure assessment with the SphygmoCor System, and the Zoll Heart Failure and Arrhythmia Management System for monitoring pulmonary fluid levels. The bulletin is titled CPB 0548, reviewed 2025-08-22, with a last review of 08/21/2026.
Continuous renal replacement therapy may be considered medically necessary as supportive treatment for acute renal failure. CPT 90945 and 90947 cover dialysis procedures other than hemodialysis, including hemofiltration and other continuous renal replacement therapies. The policy was reviewed on 01/14/2026 with its policy statement unchanged, and ICD-9 diagnosis codes were removed from the code reference.
