For billers and coders, staying current on payer-specific coverage criteria, reimbursement rules, and prior-authorization requirements for HCPCS L5841 is critical to clean claim submission. Each entry below links to the full policy analysis with effective dates and action steps.
Starting January 1, 2027, Sentara Health Plans will require prior authorization for a long list of codes on Virginia commercial plans, including self-funded (ASO) plans, and for code 88380 on commercial, Medicaid and Medicare products, plus code 22860 on Medicare products. Sentara will also stop covering a separate list of codes on Virginia commercial and self-funded plans.
Effective July 1, 2026, multiple policy changes include removing prior authorization for chronic liver disease testing (CPT 0344U), adding prior authorization requirements for tibial nerve stimulation, changing orthognathic surgery codes to use general prior authorization criteria instead of specialty-specific criteria, and updating various other testing and procedure requirements across Medicare Advantage and commercial plans.
This is a health plan medical policy for definitive (permanent) lower limb prostheses, effective November 1, 2026, which is already in effect as of the analysis date. It sets the conditions under which a new prosthesis, a component replacement or a socket replacement is considered medically necessary, including an in-person functional assessment and a functional level (K0 to K4), and it lists the HCPCS codes the policy applies to. Prior authorization is required only for definitive prostheses, not preparatory ones, so check the plan's prior authorization website to confirm.
Medical Policy DME18, Definitive Lower Limb Prostheses, is effective November 1, 2026. A definitive (permanent) lower limb prosthesis may be considered medically necessary when the individual is motivated to ambulate with it, the residual limb has matured, the individual has achieved a defined functional state (K0 to K4) and is cognitively capable of using it to ambulate effectively, and the individual had an in-person medical evaluation with a comprehensive functional assessment using a validated assessment tool or equivalent standardized measures. Prior authorization is required only for definitive prostheses, not preparatory ones. Replacement may be considered medically necessary for a change in the individual's physiological condition, an irreparable change in the device or a part of it, or repairs costing more than 60 percent of the cost of a replacement. Replacement sockets (L5700 to L5703) also require documented functional or physiological need. Replacements with upgraded features that exceed the individual's functional needs are considered not medically necessary.
Section 110.8 of the Medicare Benefit Policy Manual is updated to reflect DMEPOS benefit category determinations for the 2025 biannual 1 and 2 Level II HCPCS coding cycles. Each listed code is assigned a benefit category, such as DME, Prosthetic Device, Back Brace, Leg Brace, Prosthetic (Artificial Leg or Arm), Lymphedema Compression Treatment Item, or No Medicare DMEPOS benefit category. This update makes no change in policy.
