CMS published Final Rule FR-2026-15446 in the Federal Register on July 30, 2026, amending three DMEPOS administrative lists: the Master List of Items Potentially Subject to Face-to-Face Encounter and Written Order Prior to Delivery requirements, the Required Face-to-Face Encounter and Written Order Prior to Delivery List, and the Required Prior Authorization List. The rule takes effect October 28, 2026. Any HCPCS code newly added to the Required Prior Authorization List that is submitted without an approved prior authorization on or after that date will be denied at the claim level — there is no grace period stated in the source document.
Regulatory Background CMS maintains statutory authority under Section 1834(a)(11) of the Social Security Act to require prior authorization for DMEPOS items identified as having high rates of unnecessary utilization or improper payment. Periodic updates to these lists reflect CMS's ongoing program integrity monitoring, which identifies HCPCS codes where claims data indicate elevated vulnerability to fraud, waste, or abuse. This final rule represents CMS's determination — following any applicable proposed rule and comment period — that the designated codes now meet the threshold for mandatory prior authorization or face-to-face documentation requirements prior to delivery.

Quick answers
If a DMEPOS order was initiated before October 28, 2026 but the item is delivered after that date, does the new prior authorization requirement apply?
The final rule FR-2026-15446 establishes October 28, 2026 as the effective date for the updated lists. Prior authorization requirements under the DMEPOS PA program are generally tied to the date of service (delivery date), not the order date. Orders for newly listed codes that result in delivery on or after October 28, 2026 should be treated as requiring prior authorization. Confirm the date-of-service applicability with your DME MAC jurisdiction before assuming pre-effective-date orders are grandfathered.
Does the Required Prior Authorization List update under FR-2026-15446 apply to all DME MAC jurisdictions, or only specific regions?
The Required Prior Authorization List established under CMS's DMEPOS prior authorization program applies nationally across all four DME MAC jurisdictions. FR-2026-15446 is a federal final rule, not a jurisdiction-specific LCD or local policy. All suppliers billing Medicare Part B for newly listed HCPCS codes must comply regardless of geographic location beginning October 28, 2026.
What documentation must be retained for HCPCS codes newly added to the Required Face-to-Face Encounter and Written Order Prior to Delivery List?
Under the face-to-face requirements applicable to DMEPOS, the supplier must retain evidence that the treating physician or allowed practitioner conducted an in-person encounter and that a compliant written order — containing all required DMEPOS order elements — was completed prior to delivery. The medical record supporting the encounter must be available upon ADR request from the DME MAC.
