Each entry below links to the full policy analysis with effective dates and action steps.
CareSource is implementing comprehensive claim edits for durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) effective June 10, 2026. Billing teams must use correct modifiers (rental, anatomical, functional, and surgical dressing modifiers) for all DMEPOS claims to prevent denials. Additionally, breast pump codes are now limited to one unit per delivery across all providers over a 240-day period.
Sentara Health Plans relaxed prior authorization requirements for 499 codes for commercial products offered in Virginia, covering categories such as medical and surgical supplies, cardiovascular procedures, proprietary laboratory analyses and outpatient PPS codes. Effective February 1, 2026, commercial prior authorization is required for a further set of codes, several psychological testing codes now require authorization only after the listed hour limits, and several commercial codes, including 99070, A9286, G0330 and S9152, are not covered. Self-funded commercial products had separate prior authorization and not-covered code lists effective February 1, 2026, and Medicaid changes took effect October 1, 2025 and December 1, 2025.
CareSource is implementing new claim edits for durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) effective January 17, 2026, requiring correct use of modifiers (rental, anatomical, functional, surgical dressings, and other) to prevent claim denials. The policy also establishes a limitation of one breast pump per delivery (240 days/eight months) and applies CMS payment policies across multiple DMEPOS categories.
CareSource is implementing new claim edits for durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) effective January 15, 2026, aligning with CMS payment policies. Billing teams must ensure correct use of modifiers (rental, anatomical, functional, and surgical dressing modifiers) on all DMEPOS claims to prevent denials. Key restrictions include limiting breast pumps to one unit per delivery (240 days/eight months) and applying state guidelines.
Effective December 22, 2025, prior authorization is required for all prescriptions for hospital grade breast pumps after six months of rental, and the updated guidelines set the criteria for continued rental. Continued rental is medically necessary when the beneficiary is unable to nurse and provide adequately for the infant and personal use of manual or electric breast pumps does not adequately meet maternal or infant needs, or when the beneficiary takes medications that can be found in breast milk and would harm the infant.
Rental of a reusable breast pump is considered medically necessary for the period of time that a newborn is detained in the hospital after the mother is discharged. For babies with congenital disorders that interfere with feeding, a breast pump is considered medically necessary for up to 12 months of age. Purchase of a heavy duty electrical (hospital grade) breast pump or a wearable, battery-operated electric breast pump is considered not medically necessary.
Effective January 1, 2023, claims billed with HCPCS 2023 procedure codes may begin suspending for EOB 0000, and claims will be released once the Colorado interChange update is complete. Effective January 1, 2023, a select group of additional physician-administered drugs require prior authorization, and prior authorization for CPT 92526 is no longer required when billed with CPT 74230 and 92611, while the multi-user breast pump rate for E0604 with modifier RR is $219.67. Depression screen claims using G8431 or G8510 must include U modifiers beginning July 1, 2023, after that requirement was postponed again, and claims without modifiers will be denied.
