Which pin to choose?
The two-part pin has been our standard for years.
The solid brass pin can be quieter and has a higher pull strength.
The thread is determined by which liner you choose.

If lock plate replacement is happening frequently make sure you are adjusting pin spacers to minimize pistoning. If the prosthetic is used in a gritty, sandy environment you might have the patient clean out the bottom of the socket more frequently.

CD103LP – is the part number for the replacement lock plate which includes three replacement springs. This part can be used for the Air-Lock, Small Air-Lock, Medium Air-Lock, Drop-In Air-Lock, and the Air-Lock Locking Lanyard. 

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® believes that “suction” in a prosthetic refers to the 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.

**The CD117 Easy-Off Lock can be used with a vacuum system and will maintain vacuum levels. Both lock code and vacuum code can be billed when using dual suspension. Not recommended for billing with Medicare.
