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. When an initial below knee prosthesis (L5500) or a preparatory below knee prosthesis (L5510, L5520,L5530, L5540) is provided, prosthetic substitutions and/or additions of procedures and components are covered in accordance with the functional level assessment except for codes L5629, L5638, L5639, L5646, L5647, L5704, L5785, L5962, and L5980 which will be denied as not reasonable and necessary. When a below knee preparatory prefabricated prosthesis (L5535) is provided, prosthetic substitutions and/or additions of procedures are covered in accordance with the functional level assessment except for codes L5620, L5629, L5645, L5646, L5670, L5676, L5704, and L5962 which will be denied as not reasonableand necessary.You can find this information in Medicare's 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 (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 beneficiary's history and current condition which supports the designation of the functional level by the prosthetist.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).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.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).L5968 describes a device with multiaxial ankle motionalong with an active dorsiflexion motion activated for swing phase only.Use of L5968, L5982, L5984 or L5986 is based on the beneficiary's K-level modifier (K0-K4), as referenced in the LCD.L5968, L5982, L5984, L5985, L5986, L5988, L5990 are additionalfeatures 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.Protective outer surface covering systems (L5962, L5964, and L5966) are specialized covers intended to be worn over an existing prosthesis. They are used by a beneficiary who has special needs for protection against unusually harsh environmental situations where it is necessary to protect the lower limb prosthesis beyond the level of protection that is afforded by L5704, L5705, L5706, and L5707. They are not for cosmetic or convenience reasons, or for everyday usage in a typical environment. Protective outer surface coverings are different from the covering that is already reimbursed as part of L5704, L5705, L5706, and L5707.You can find this information in Medicare's Local Coverage Article: Lower Limb Prostheses -Policy Article (A52496).If you want to read these Medicare rules, you can go to this website www.medicareappeal.com
