CMS adds 8 DMEPOS codes to its prior authorization list and 22 to the face-to-face list, effective October 28

Eight more DMEPOS codes need an approved prior authorization before Medicare will pay them, and 22 more need a documented face-to-face encounter and a written order before the item is delivered. CMS put all of it in a rule published in the Federal Register on July 30, 2026.

If you bill orthoses, manual wheelchairs, or a handful of bed, oxygen, and ventilator codes, this is a workflow change with a date on it, not a memo to file. Whether a given code gets a new prior authorization requirement or a new face-to-face and written-order step depends on which list it landed on, so read the two separately.

What the rule changes

The rule touches three separate lists, all set up by CMS's November 2019 DMEPOS final rule (84 FR 60648). The Master List and the Required Prior Authorization List are codified at 42 CFR 414.234; the Face-to-Face/Written Order Prior to Delivery (F2F/WOPD) requirement sits at 42 CFR 410.38. The Master List is the pool of DMEPOS items CMS considers potentially subject to extra conditions of payment. The F2F/WOPD List and the Required Prior Authorization List are the two subsets that carry an actual requirement.

This update adds 20 codes to the Master List and removes none. It adds 22 codes to the F2F/WOPD List, which takes that list from 83 items to 105. And it adds eight codes to the Required Prior Authorization List, which currently carries 74.

The prior authorization list is the one that changes what gets paid. On that list, an approved prior authorization request is a condition of payment: submit the claim without one and it's denied.

The eight codes that now need prior authorization

CMS picked one pressure-reducing support surface, one manual wheelchair base, and six orthoses.

The other 74 codes already on the prior authorization list keep running without interruption. Nothing you already prior-authorize changes.

When each code takes effect

Six of the eight codes carry a single national start date of October 28, 2026. The two upper-limb orthosis codes, L3761 and L3916, roll out in three phases so CMS can watch smaller claim volumes first.

So a supplier billing an off-the-shelf wrist-hand orthosis in California is inside the requirement from day one, while the same code in Colorado isn't covered until the nationwide phase in April 2027. Read the phase table against the states you actually ship to before you build the workflow.

The 22 codes added to the face-to-face and written-order list

The F2F/WOPD requirement is documentation, not payment approval, but a missing element denies the claim just the same. CMS is adding three lumbar-sacral orthosis codes, four lower-limb orthosis codes, two upper-limb orthosis codes, eight wheelchair codes, three home-ventilator codes, one oxygen code, and one air-fluidized-bed code.

For any item on this list, the treating practitioner has to have a face-to-face encounter with the patient within the six months before the date of the written order, and the written order has to reach the supplier before delivery. CMS notes the encounter can be a telehealth visit where that's appropriate under its coverage rules, and it has to be documented in the medical record with the beneficiary-specific findings that justify the item. This is the same documentation-completeness problem behind a lot of Medicare denials: the item may be perfectly appropriate, but if the note or the order is missing or out of sequence, the claim doesn't survive review.

Why CMS made the change

CMS tied the additions to its own error data. The agency reported that from 2023 to 2025, Comprehensive Error Rate Testing (CERT) improper-payment rates ran roughly 40 to 48 percent for upper-limb orthoses, 35 to 47 percent for lower-limb orthoses, and 22 to 42 percent for manual wheelchairs. It also noted that its Fraud Defense Operations Center has suspended more than $1.5 billion in DMEPOS payments tied to suspected fraudulent billing. Eight of the 20 new Master List codes were added specifically for aberrant billing patterns, which CMS flags when an item drew at least 1,000 claims and $1 million in payments in a year and its payments jumped by more than the greater of 30 percent or twice the change across all DMEPOS. Each of these eight cleared the 30 percent mark.

The pattern here is the same one behind the quarterly NCCI edit expansions and the contractor medical reviews of high-volume E/M codes: CMS aims a specific control at a service type once its error rate stays high, and the burden lands on the biller to get the documentation and the authorization right before the claim goes out. It lands in the same place as the broader rise in payer audits and coding denials: the record has to be built before the claim, not after the denial.

What this does and does not touch

This is a Medicare Part B fee-for-service payment rule for durable medical equipment. It doesn't change how a diagnosis maps to an HCC, and it doesn't touch a Medicare Advantage risk-adjustment score. If your work is on the risk-adjustment side, this one is context, not a task. If your work is on the provider-office or DME-supplier claim side, it's a dated workflow change, and October 28 is close. Pull the affected codes, confirm which of your states are in the first phase, and get the prior authorization and face-to-face steps into intake before the effective date rather than after the first denial.
