Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 77072 covers

A bone age study uses radiographic images, typically of the hand and wrist, to assess skeletal maturity. A radiologist or other qualified interpreting practitioner evaluates the images and estimates how developed the bones appear relative to expected maturation. Pediatricians and pediatric endocrinologists commonly request the study when evaluating growth concerns or disorders that can affect development. The clinical question is skeletal maturity, not bone density or the length of a limb.

Select this code when the service performed is a bone age assessment, and retain documentation supporting the reason for the study and the interpreting report. CMS recognizes a professional component for interpretation and a technical component for the equipment and staff; bill modifier 26 for the professional portion or modifier TC for the technical portion. Billing without either modifier represents the global service, including both components.
