Documentation Requirements for CPT Code 73630

To prevent denials, your documentation should include:

  • Medical necessity for the X-ray
  • Indication (injury, pain, trauma, swelling, etc.)
  • Number of views (≥ 3)
  • Laterality (right, left, or bilateral)
  • Radiologist interpretation report
  • Date and location of imaging

Best practice: Always document “minimum of three views performed.”

Reimbursement for CPT Code 73630

Reimbursement depends on:

  • Facility vs. non-facility setting
  • Geographic pricing
  • Whether the professional or technical component is billed

  • Non-Facility: $35–$50
  • Facility: $10–$25 (technical may already be included)

Private payers may reimburse higher.

CPT Code 73630 Billing & Coding Tips

Here are key medical billing insights to reduce denials:

Use RT/LT for all unilateral studies

Many payers automatically deny claims without laterality.

For bilateral imaging

Check whether payer prefers:

  • Modifier 50, or
  • RT + LT with 1 unit each

Avoid unallowed bundling

Never bill 73650 or 73660 with 73630 for the same foot.

Ensure radiology report is complete

Missing interpretations cause many denials.

Watch for medical necessity

Screening X-rays are not covered.

Clinical Conditions Justifying CPT 73630

  • Trauma or injury

Bundled codes include procedures already covered within a primary CPT code. For example, CPT 73630 includes toes and heel, so 73650 (calcaneus X-ray) and 73660 (toe X-ray) are considered bundled if performed on the same foot.
