Documentation requirements

What must appear in the operative or office note to support the claim.

Source · Editorial brief grounded in 5 cited references ↓

  • Number of views obtained (minimum two for 73100; document each view taken)
  • Clinical indication or ICD-10 diagnosis code supporting medical necessity (fracture, pain, dislocation, etc.)
  • Radiologist or interpreting physician's signed written report with findings and impression
  • Laterality documented — left, right, or bilateral — to support LT/RT modifier use
  • Order or requisition from referring or treating provider on file

What this code covers

Source · Editorial summary grounded in 5 cited references ↓

73100 covers a two-view (or more) plain film radiographic examination of the wrist. It's the go-to code for initial fracture workup, post-reduction checks, and evaluating wrist pain of unclear origin. The minimum two-view requirement distinguishes it from 73110 (three or more views); if you took only one view, bill 73100 with modifier 52.

Billing splits by who owns the equipment and who reads the film. If your orthopedic practice performs and interprets in-house, bill globally. If a radiologist interprets only, append modifier 26. If the facility owns the equipment and bills the technical portion separately, use modifier TC. In a hospital outpatient setting, the facility captures the technical component under HOPD rates; the interpreting physician bills 73100-26.

Never report 73100 separately when it's bundled into an imaging-guided procedure — NCCI policy bars separate reporting of radiology codes that are integral to another procedure on the same date. When 73100 is billed alongside an E/M on the same visit for a new wrist complaint, no modifier is needed on the imaging code itself; modifier 25 belongs on the E/M.

Common denial reasons

The recurring reasons claims for CPT 73100 get rejected.

Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓

  • Only one view taken but modifier 52 not appended — payer downcodes or denies without reduced-service documentation
  • Radiology report missing or unsigned at time of claim submission
  • 73100 billed globally when facility owns equipment — results in a split-billing conflict requiring modifier 26 on the professional claim
  • Lack of medical necessity documentation — ICD-10 code too vague (e.g., unspecified wrist pain) without supporting clinical notes
  • Duplicate claim when both the facility and the physician bill the global code without proper TC/26 split

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 5 cited references ↓

01What's the difference between 73100 and 73110?
73100 covers two or more views; 73110 covers three or more views. The view count in the radiology report determines which code is correct. Don't upcode to 73110 if only two views were taken.
02If only one view was obtained, how should I bill?
Bill 73100 with modifier 52 to indicate a reduced service. Document why only one view was taken. Some payers may have a specific policy on this — confirm before submitting.
03Do I need modifier 25 on the E/M when 73100 is billed same-day?
Modifier 25 goes on the E/M code, not on 73100. Apply modifier 25 to the E/M only if it represents a significant, separately identifiable service beyond the decision to order the X-ray.
04When should I use modifier 26 versus billing 73100 globally?
Bill globally only if your practice owns the equipment and the physician interprets the study. If a hospital or independent imaging center owns the equipment, the interpreting physician bills 73100-26 only. Billing globally in that scenario will cause a duplicate-payment conflict.
05Can 73100 be billed bilaterally with modifier 50?
Yes, if both wrists are imaged at the same encounter. Use modifier 50 for bilateral, or LT/RT on separate line items depending on payer preference. Document both studies in the radiology report.
06Is 73100 ever bundled into a fracture care code?
NCCI policy bars separate reporting of imaging that is integral to another procedure on the same date. However, a diagnostic wrist X-ray taken to evaluate and diagnose a fracture before any procedural intervention is generally separately reportable. Document the timeline clearly — image first, procedure decision second.

Mira AI Scribe

Mira's AI scribe captures the number of views obtained, the laterality of the study, and the clinical indication from dictation — preventing the two most common 73100 denials: missing view count and absent laterality. It also flags when a global bill is inappropriate because the interpreting physician doesn't own the equipment, prompting the correct modifier 26 before the claim goes out.
