Compression is an essential component of both healing and preventing venous leg ulcers. Not only do compression garments, such as the EXTREMIT-EASE® Compression Garment, help to treat difficult lower leg ulcers, they can also be stocked in our office and dispensed to patients as a DME item, providing your patients with excellent care and providing your office with profits.
Coding for Compression
For garments that provide 30-50 mmHG, the appropriate HCPS code is A6545 (Gradient compression wrap, non-elastic, below knee, 30-50 mmHg, each). It is important that the diagnosis codes pointing to A6545 represent a lower extremity ulcer requiring compression. These include the I83- or I87- code listed first to identify the underlying condition followed by the L97- code to identify the severity of the ulcer.
Do Not Forget the Modifiers!
When billing for compression, the -A modifier referred to in last month’s blog should not be used. Instead, the A6545 code must have an -AW modifier appended to it (Item furnished in conjunction with a surgical dressing.). The -AW modifier should only be used with codes for certain compression garments, including EXTREMIT-EASE, and tape codes A4450 and A4452.
In addition to the -AW modifier, a laterality modifier of either RT (for right leg) or LT (for left leg) should be appended to the A6545 code.
Example
An example of proper coding when the EXTREMIT-EASE Compression Garment is dispensed would be:
- Diagnosis codes I83.222 (Varicose veins of lower-left extremity with both ulcer of calf and inflammation) followed by L97.221 (Non-pressure chronic ulcer of left calf limited to breakdown of skin),
- Pointing to A6545, with
- Both AW and LT modifiers appended
