With the elimination of the least costly alternative (LCA) determination, the following rules apply under this new guidance:
by Sarah Hanna

In December, the DME MACs were instructed by CMS that they can
no longer make partial payment for claims based on a “least
costly alternative” (LCA) determination. For claims with
dates of service on or after Feb. 4, 2011, the following rules
apply under this new guidance:

1) If the Local Coverage Determination (LCD) currently states
that an item will always be paid based on allowance for the least
costly item (if the criteria for the less costly item are met),
then under the new policy, a claim for that item will always be
denied as not medically necessary
(Type 1 LCA denial).

2) If the LCD currently states that an item will be paid in full
if specific additional coverage criteria are met but will be paid
based on the allowance for the least costly item if the additional
coverage criteria for the billed item are not met (and if the
criteria for the less costly item are met), then under the new
policy, a claim for that item will be denied as not medically
necessary if all of the additional coverage criteria for that item
are not met (Type 2 LCA denial).

The claim will be paid in full if the additional coverage
criteria are met.

  • If a KX modifier is required to attest to the additional
    coverage criteria being met, claims without a KX modifier (and with
    a GA, GY or GZ modifier) will be denied.

    Billers need to be aware of this change so they can gain
    additional documentation to prove the medical necessity of the item
    being dispensed/billed — and know how to work these denials
    when they are received. If a base code for an item of DMEPOS is
    denied as not medically necessary, all related accessories,
    supplies, additions and drugs also will be denied as not medically
    necessary.

    Least costly alternative statements are found in the following
    LCDs (note that the information may not be all-inclusive, so refer
    to each LCD for details): ankle-foot/knee-ankle-foot orthoses;
    canes and crutches; cervical traction devices; commodes; enteral
    nutrition; external breast prostheses; external infusion pumps;
    glucose monitors; hospital beds; knee orthoses; manual wheelchairs;
    nebulizer equipment and related drugs; patient lifts; pneumatic
    compression devices; PAP devices; power mobility devices;
    respiratory assist devices; seat lift mechanisms; surgical
    dressings; therapeutic shoes for persons with diabetes;
    tracheostomy supplies; urological supplies; walkers; wheelchair
    options and accessories; and wheelchair seating.

    One thing to be aware of regarding capped rental DME items:
    Elimination of LCA determinations will apply only to claims in
    which the date of service for the initial rental month is on or
    after Feb. 04, 2011. If an LCA determination is made on an item
    with an initial rental month DOS prior to that date, subsequent
    claims for that item will continue to be adjudicated using the LCA
    determination for the duration of that rental period. If an item is
    denied in full due to elimination of the LCA, partial payment based
    on the LCA will not be possible through the appeals process.

    For items that were previously paid based on an LCA
    determination, suppliers can receive partial payment at the time of
    initial determination if they elect to bill using one of the
    upgrade modifiers, GK or GL.
