Radiology

About 77073: Lower extremity bone length study

Reports radiographic measurement of lower-extremity bone lengths, commonly used to evaluate limb-length differences and guide orthopedic assessment or treatment.

This study uses radiographs to compare lower-extremity bone lengths, often when a patient has a suspected limb-length difference or is being assessed for an orthopedic growth or alignment concern. It is commonly performed in radiology departments and imaging centers, with a radiologic technologist acquiring the images and a radiologist interpreting them. Orthopedic clinicians may use the findings in evaluating children with unequal limb growth and patients being considered for corrective treatment.

Report 77073 for the bone-length examination, rather than a routine radiograph of one bone or joint. The order and report should support the limb-length question and identify the structures assessed and the interpretation. CMS recognizes professional and technical components: report modifier 26 for the interpretation, modifier TC for the equipment and staff, or no modifier when billing the global service. The component may be billed separately when the service is split between practitioners or entities.

CMS billing rules for 77073

Professional and technical components

77073 billing questions

When should 77073 be chosen instead of a bone-age study?

Use 77073 when the imaging question is lower-extremity bone length or limb-length difference. A bone-age study, such as 77072, evaluates skeletal maturity.

How are the professional and technical services reported?

Use modifier 26 for the professional interpretation and modifier TC for the technical service. Without either modifier, the claim represents the global service.

Can dedicated femur or tibia and fibula films also be reported?

They may be separately reported when the clinician orders distinct diagnostic views for a separate clinical question. The documentation should support that additional examination, rather than simply restating the bone-length assessment.

What documentation supports 77073?

The order and report should identify the lower-extremity length question and document the structures evaluated and the radiologist’s findings.

Is 77073 the same as a skeletal survey?

No. It assesses lower-extremity bone lengths; a skeletal survey examines bones for a broader or different diagnostic purpose.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
