The rules say that plans must pay for a medical service or item if regular Medicare would pay for it in this case. 
You can find this rule at 42 Code of Federal Regulations (CFR) Section 422.101. 
 
The rules say that a microprocessor controlled ankle foot system (L5973), energy storing foot (L5976), 
dynamic response foot with multi-axial ankle (L5979), flex foot system (L5980), flex-walk system or equal 
(L5981), or shank foot system with vertical loading pylon (L5987) is covered for beneficiaries whose 
functional level is 3 or above. 
 
An axial rotation unit (L5982, L5984, L5985, L5986) is covered for beneficiaries whose functional level is 2 or 
above. You can find this rule in the Local Coverage Determination (LCD) Lower Limb Prostheses L33787. 
 
The rules say that when submitting a prosthetic claim, the billed code for knee, foot, ankle and hip (codes 
L5610, L5611, L5613, L5614, L5616, L5710, L5711, L5712, L5714, L5716, L5718, L5722, L5724, L5726, 
L5728, L5780, L5810, L5811, L5812, L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840, 
L5848, L5856, L5857, L5858, L5859, L5930, L5961, L5970, L5971, L5972, L5973, L5974, L5975, L5976, 
L5978, L5979, L5980, L5981, L5982, L5984, L5985, L5986, L5987) components must be submitted with 
modifiers K0 - K4, indicating the expected beneficiary functional level. This expectation of functional ability 
information must be clearly documented and retained in the prosthetist's records. The simple entry of a K 
modifier in those records is not sufficient. There must be information about the beneficiarys history and 
current condition which supports the designation of the functional level by the prosthetist. 
 
Codes L5968, L5982, L5984, L5985, L5986 and L5988 describe separate products which provide either a 
single motion or a combination of motions generally attributed to functional movement of the lower limb 
during ambulation. The use of these codes can be used to fully describe additional features or functions not 
found in the prosthetic. 
 
L5981 describes a product that can be used for either endoskeletal or exoskeletal lower limb construction. The 
Flex Walk has an energy storing J-shaped keel design. Heel component is attached to the J-shaped keel section. 
The Flex Walk J-shaped keel design proximally terminates at a nonadjustable fixed height determined and 
modified by the prosthetic foot manufacturer. L5981 includes foot cover. 
 
 L5986 describes a product that is used as an addition to L-code foot systems for lower limb prosthesis 
construction. The product provides multiaxial motion in all three planes of motion, sagittal, coronal, and 
transverse. This code does not describe the multiaxial motion achieved from the inherent flexibility of the 
prosthetic keel or a split keel/heel prosthetic foot design. The predicate product is a device that was 
manufactured by Medical Center Prosthetic, which is represented in the coding narrative by MCP. 
 
Use of L5968, L5982, L5984 or L5986 is based on the beneficiarys K-level modifier (K0-K4), as referenced 
in the LCD. You can find these rules in the Local Coverage Article Lower Limb Prostheses - Policy Article 
A52496.

The Plan contract says that the Plan covers items and services in accordance with Medicare rules.
