What 76983 covers
This add-on represents elastography assessment of a target lesion beyond the first lesion evaluated. Ultrasound elastography measures tissue stiffness as part of diagnostic imaging. A physician, often a radiologist or another clinician performing diagnostic ultrasound, interprets the images; the technical work involves the ultrasound equipment and staff supporting image acquisition. The code is for additional target lesions, not a general assessment of organ parenchyma.
Report 76983 with the primary first-lesion service, 76982, for each additional target lesion assessed. The record should support the number of distinct additional lesions evaluated and the elastography work performed. This is an add-on code, so it is billed only with its primary procedure and payment falls within that procedure’s global period. The diagnostic service may be billed globally or split into professional interpretation with modifier 26 and technical services with modifier TC.

76983 billing questions
When should 76983 be reported instead of 76982?
Use 76982 for the first target lesion assessed with elastography. Report 76983 for each additional target lesion evaluated in the same service.
Can 76983 be billed without 76982?
No. It is an add-on code and must be reported with the primary first-lesion elastography service, 76982.
How many units should be reported?
Report one unit for each additional target lesion assessed after the first. Documentation should identify the additional lesions and support the elastography assessment.
Can the professional and technical work be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
How does 76983 differ from 76981?
76983 covers each additional target lesion after the first. 76981 is for elastography assessment of organ parenchyma rather than an additional targeted lesion.
