Compression is a serious thing and more complicated than most people realize. Please make sure that you know this person has sufficient ABI's to be compressed. Also, a physician is able to write for whatever mmHg compression he thinks the patient can tolerate based upon the pt's ABI or venous/arterial doppler ultrasound study. Compression stockings will be 100% covered by Medicare in the presence of venous stasis ulcers, no matter how small, shallow, or minute.
There are many types of compression, ranging from tubigrip or tubifast which can provide 8-12mmHg at 50% stretch, all the way to Profore which can provide up to 60mmHg compression. Also, is your patient ambulatory? This can also dictate the type of compression necessary. Most non ambulatory patients will benefit from a high stretch type of compression dressing (ace, etc) while ambulatory patients benefit more from short stretch (unna's boot, coban, etc). This is because the non ambulatory people need continuous compression, allowed by the high stretch bandage conforming to their limb. Conversely, the ambulatory individuals need the short stretch to provide a high working pressure (compression occurs during ambulation with "milking" of the calf muscle), and a low resting pressure (allowing for the patient to elevate the LE's when not ambulating to reduce edema).
Please consult with someone who is experienced in compression-it is easy to injure someone if done incorrectly.
Also, lymphedema pumps are the best medical devices for those with venous stasis, as nearly 90% of VS patients have a lymphatic component to their edema (this must be stated by the physician in documentation in order for the pumps to be paid for). These are not SCD's, they go thigh high and have different mmHg settings, which are also set forth by the physician at the time of prescription. Hope this helps!
