Which pin to choose?

The two part pin has been our standard for years.
The solid brass pin can be a quieter and has a higher pull strength.
The thread is determined by which liner you choose.
There is not a deep version of the drop in locks so the 11 click pins can not be used.

Billing Information

Recommended Codes:

L5671 Addition to lower extremity, Below Knee/Above Knee suspension locking mechanism
(shuttle, lanyard or equal), excludes socket insert.

L5647* Addition to lower extremity, Below Knee, suction socket.

L5652* Addition to lower extremity, suction suspension, Above Knee or Knee Disarticulation Socket.

*Not recommended for billing Medicare. Coyote Design® believes that “suction” in a prosthetic refers to negative pressure created inside the socket, rather than componentry such as an expulsion valve or sleeve. Because we think of suction as a function, we believe it should be permitted to bill L5671 in conjunction with the L5647 or L5652 in cases when it is medically necessary. As with other situations where multiple suspension methods are used and billed we feel the combination of a lock and suction helps to increase safety for the patient.
