In-Office Imaging in Orthopedic Claims: X-Rays, Interpretations, and Outside Films

Imaging is central to orthopedic visits

Most orthopedic visits involve imaging. Practices take radiographs in the office, review MRI and CT studies ordered from imaging centers, and sometimes perform ultrasound or bone density studies. Each kind of imaging raises billing questions: whether the practice bills the global service, only the technical component, or only the professional component; what documentation supports the interpretation; and how reviewing outside images is captured. Imaging is a meaningful revenue source for orthopedic groups, and errors can lead to duplicate billing with radiologists or to missed interpretations.

Global, technical, and professional components

When an orthopedic practice owns its X-ray equipment, employs the technologist, and the orthopedist interprets the films, the practice bills the global service without a modifier. When the practice takes the image but a radiologist interprets it under a separate arrangement, the practice bills the technical component with modifier TC and the radiologist bills the professional component with modifier 26. When the orthopedist interprets images taken at a hospital, the orthopedist may bill only the professional component, with modifier 26, if a separate formal report is created and the payer recognizes the orthopedist's interpretation.

Documentation for the interpretation

A billable interpretation requires a written report. Medicare guidance describes a formal interpretation report as including the indication, findings, and impression, signed by the interpreting physician, and expects it to be a separate, identifiable element in the record. A brief note in the E/M stating that X-rays showed no fracture is generally not sufficient to support a separately billed professional component. Many practices use a template that creates a separate imaging report within the visit note for each study.

Choosing the correct number of views

Radiology codes for extremities and spine are often defined by the number of views, such as two views or minimum of three views, and some include specific projections. The technologist's record and the report should list the views obtained, and the code must match. When fewer views are taken than the code requires, the lower code applies. Bilateral studies may be reported with modifier 50 or with separate units and laterality modifiers RT and LT, depending on the code and payer.

Outside imaging and review of existing films

Reviewing images or reports from studies performed elsewhere, such as an MRI from an imaging center, is generally not separately billable as an interpretation because a radiologist has already billed the professional component. That review contributes to medical decision making. Under the current E/M guidelines, an independent interpretation of a test performed by another physician can count toward the data element when the orthopedist does not bill for it. Do not bill a 26 modifier for reviewing outside studies that already have a final report.

Medical necessity and repeat imaging

Payers expect each imaging study to be supported by a documented indication. Routine imaging at every follow-up visit without a clinical reason, such as checking fracture healing at expected intervals or evaluating new symptoms, may be questioned. Some payers limit how often certain studies are covered. When a repeat study is needed on the same day, such as post-reduction films, append modifier 76 and document why. Advanced imaging ordered by the practice and performed elsewhere often requires prior authorization through a radiology benefit manager.

Equipment and supervision requirements

Diagnostic X-rays performed in a physician office require appropriate supervision under Medicare rules, which list supervision levels for each diagnostic test. State laws also regulate radiologic technologist licensure and equipment registration. Some payers also require that in-office imaging meet accreditation standards, particularly for advanced imaging such as MRI or CT. Confirm requirements before adding new imaging services.

A worked example

A patient arrives with wrist pain after a fall. The orthopedic practice takes three views of the wrist in the office, and the surgeon reviews them during the visit, identifies a nondisplaced distal radius fracture, and decides on closed treatment without manipulation. The practice owns the equipment and the surgeon writes a separate report with indication, findings, and impression, so the practice bills the wrist radiograph code for a minimum of three views globally, without a modifier, with RT or LT as required by the payer. The fracture care code is billed for the treatment, and the E/M may or may not be separately reportable depending on payer rules and whether the decision for treatment was the only significant service. At the follow-up visit within the fracture care global period, new radiographs taken to check alignment are billed separately, because imaging is not part of the global package, while the visit itself is included. If the patient had brought a hospital emergency department X-ray already read by a radiologist, the surgeon's review would count toward decision making but would not be billed as an interpretation.
