After years of the spine compressing down on discs, the lower back becomes soar and stiff. Rather than letting the world pass you by while you watch in agony, you may choose to go to your doctor for treatment. Medical insurance companies want to be sure that the treatment that is being given is the correct one, that's why there are medical billing codes, such as the L0641, to monitor requirements for orthosis. The billing code L0641, in particular, pertains to a lower back, or lumbar, brace.
A lumbar support with the billing code L0641 must have control over side to side motion. The backside must also contain at least one rigid panel. The back side of the brace covers all 5 lumbar vertebra.
Like many other back braces, this brace must create pressure within the body in order to redistribute the load that normally falls on the lumbar region. This relieves the discs, allowing the back time to heal. A support of this nature must also be equipped with closures and adjustment straps. The support may also include padding, stays, shoulder straps, or a design meant for an individual with a pendulous abdomen, however whether or not these are included has no effect on the L0641 billing code assigned to it.
This type of brace is not fashioned specifically for one individual. The L0641 billing code is specific to an "off-the-shelf" status, and in order to maintain that status it can in no way be customized to fit the individual.
Braces of this nature can be bought retail. However, you should consult your doctor for proper treatment of any serious injury.
