A girl with a congenital, structural difference in leg lengths is walking in a clinic. The ICD-10-CM Alphabetical Index links the below-listed medical terms to the ICD code M21.7.
The procedure for dealing with Leg Length Discrepancy (LLD) is termed Osteoplasty. Depending on where the discrepancy is located (thigh, lower leg, or both) determines whether the bones are lengthened or shortened.
Unequal limb length (acquired), unspecified femur. M21.759 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM M21.759 became effective on October 1, 2018.
Discrepancy between the lengths of the lower or upper extremities. Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
769: Unequal limb length (acquired), unspecified tibia and fibula.

A limb length discrepancy (LLD) is when one arm or leg is longer than the other arm or leg. A difference in leg lengths is more likely to be noticed and to affect activities of daily living.
ICD-10 code: Z99 Dependence on enabling machines and devices, not elsewhere classified.
True leg length discrepancy is measured – using a tape measure – from the anterior superior iliac spine to the tip of the medial malleolus. A difference in leg length of up to 1–2 cm is considered normal by some clinicians.
Limb-length discrepancy is a difference in size between the length of both arms or both legs. Small differences in limb length are common. In fact, as many as a third of the population may have a 1 cm or less (less than ½ inch) discrepancy between their right and left legs.
There are three types of LLD: structural, functional and environmental. The structural or anatomic type is due to a difference in the actual length of the tibia or femur. This may be of congenital, post-trauma or post-surgery etiology as LLD commonly occurs following hip or knee replacement.
Anatomical leg length discrepancy can be confirmed through radiographic imaging, such as full limb X-ray or CT scan. Functional leg length discrepancies are when there is a “shortening” of the leg due to altered lower limb mechanics.
A limb-length discrepancy is when one leg or arm is shorter than the other leg or arm. The difference in length can range from a fraction of an inch to several inches. Some children are born with congenital limb differences that cause their legs or arms to grow at different rates.
After DEX assigns a Z-Code to a lab for a specific test, the DEX team will review the test application and will assign a CPT code to the test. Receiving a Z-Code for a test will occur within approximately 2 weeks from adding your test into the DEX system.

Most differences in leg length are normal. No one is perfectly symmetrical and a difference of up to 2 cm in adults is typical.
For children with a small discrepancy (less than 2 cm) a lift placed into the shoe can be an adequate treatment while some children with the same discrepancy may choose no treatment at all. For children with a predicted LLD of 2.5 cm or more a surgical operation is the best treatment for LLD.
