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 when submitting a prosthetic claim, the billed code for knee, foot, ankle and hip (HCPCS 
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. 
 
Addition codes for endoskeletal knee-shin systems are L5610, L5611, L5613, L5616, L5810, L5811, L5812, 
L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840 are considered an upgrade to the knee-
shin system. The beneficiary may qualify for an upgraded knee-shin system based on their assigned K-Level 
modifier (K0-K4), as referenced in the LCD. These HCPCS codes can fully describe a complete prosthetic 
knee-shin system commonly referred to as a base knee code. A single addition code can fully describe a 
complete knee-shin system and thus the use of two codes (L5610, L5611, L5613, L5616, L5810, L5811, 
L5812, L5814, L5816, L5818, L5822, L5824, L5826, L5828, L5830, L5840) would be considered incorrect 
coding (unbundling). 
 
L5925, L5930, L5845, L5848, L5850, L5856, L5857, L5858, L5859 are additional features and/or functions 
that do not describe a complete endoskeletal knee-shin system and must be used in combination with an L-code 
for a knee-shin system (L5610, L5611, L5613, L5616, L5810, L5811, L5812, L5814, L5816, L5818, L5822, 
L5824, L5826, L5828, L5830, L5840). The use of additional feature L-codes may also depend on the assigned 
K-Level modifier (K0-K4), as referenced in the LCD. 
 
Codes L5968, L5982, L5984, L5986 describe separate products which provide either a single motion or a 
combination of motions commonly attributed to the anatomic ankle. The use of these codes can be used to fully 
describe additional features or functions not found in the prosthetic foot system (L5969, L5970, L5971, L5972, 
L5973, L5974, L5975, L5976, L5978, L5979 L5980, L5981 and L5987). Addition codes for lower extremity prostheses, L5970, L5971, L5972, L5974, L5975, L5976, L5978, L5979, 
L5980, L5981, L5987 are considered an upgrade to the SACH foot. The beneficiary may qualify for an 
upgraded prosthetic foot based on their assigned K-level modifier (K0-K4) as referenced in the LCD. A single 
addition code (L5970, L5971, L5972, L5974, L5975, L5976, L5978, L5979, L5980, L5981, L5987) can fully 
describe a complete foot and thus the use of more than one code would be considered incorrect coding 
(unbundling). 
 
L5968, L5982, L5984, L5985, L5986, L5988, L5990 are additional features and/or functions that do not 
describe a complete prosthetic foot and may be used in combination with L5970, L5971, L5972, L5974, 
L5975, L5976, L5978, L5979, L5980, L5981, and L5987. The use of additional feature L-codes may also 
depend on the assigned K-Level modifier (K0-K4) as referenced in the LCD. 
 
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. 
 
L5984 describes an endoskeletal device that allows an adjustable, or non-adjustable, amount of vertical 
twisting motion between the foot and pelvis during ambulation. 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 rules say  a fluid, pneumatic, or electronic/microprocessor knee (L5610, L5613, L5614, L5722, L5724, 
L5726, L5728, L5780, L5814, L5822, L5824, L5826, L5828, L5830, L5840, L5848, L5856, L5857, L5858) is 
covered for beneficiaries whose functional level is 3 or above. 
 
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 these rules in the Local Coverage Determination (LCD) Lower Limb Prostheses L33787.
