In the world of diagnostic imaging and medical billing services, accuracy is everything. One small mistake in coding can lead to claim denials, delayed reimbursements, or compliance risks. Among commonly used radiology codes, the 73718 CPT code plays a crucial role in billing for lower extremity imaging procedures.
This article provides a complete, updated, and easy-to-understand explanation of the 73718 CPT code, including its description, billing guidelines, documentation requirements, and common mistakes. Whether you’re a healthcare provider, coder, or someone looking to outsource dental billing or radiology billing, this guide will help you stay compliant and efficient.
What is the 73718 CPT code?
The 73718 CPT code refers to:
MRI of the lower extremity (joint or non-joint) without contrast material
This code is used when a Magnetic Resonance Imaging (MRI) scan is performed on areas such as the hip, knee, ankle, or foot without using contrast dye. It is commonly ordered to evaluate soft tissues, ligaments, muscles, and bone abnormalities.
Unlike contrast-enhanced imaging, this procedure relies solely on magnetic fields and radio waves to produce detailed internal images.
Understanding the Procedure Behind 73718
MRI scans under this code are non-invasive and highly effective in diagnosing a wide range of conditions. Physicians often recommend this procedure when patients experience persistent pain, swelling, or limited mobility in the lower extremities.
The scan can help detect:
- Ligament tears
- Muscle injuries
- Joint abnormalities
- Bone fractures not visible on X-rays
- Early-stage tumors or infections
Because no contrast is used, the procedure is generally safer for patients with kidney issues or allergies to contrast materials.
When is the 73718 CPT code used?
The 73718 CPT code is typically used in situations where a detailed evaluation of the lower extremity is required without contrast enhancement. Physicians may order this scan when initial imaging like X-rays or ultrasounds does not provide enough information.
It is frequently used in orthopedic cases, sports injuries, and chronic pain assessments. Proper documentation of medical necessity is essential to ensure reimbursement.
Healthcare providers working with Med Billing RES often find that accurate documentation significantly reduces claim rejections and improves revenue cycles.
Key Documentation Requirements
To successfully bill for the 73718 CPT code, proper documentation is critical. Medical records must clearly justify the need for the MRI without contrast.
Important elements include:
- Physician’s order for MRI
- Patient symptoms and clinical history
- Area of the body being scanned
- Confirmation that no contrast was used
- Radiologist’s report with findings
Incomplete or vague documentation is one of the most common reasons for claim denials in medical billing services.
73718 vs 73721 CPT Code: What’s the Difference?
Many coders confuse the 73718 CPT code with similar MRI codes like 73721 CPT code or cpt code 73721.
Here’s the key difference:
- 73718 CPT code – MRI lower extremity without contrast
- 73721 CPT code – MRI of any joint of the lower extremity without contrast
Although they sound similar, the distinction lies in whether the imaging focuses specifically on a joint or a broader extremity region. Incorrect code selection can lead to audits or denied claims.
Comparison with Other Imaging Codes
To better understand where the 73718 CPT code stands, it helps to compare it with other commonly used imaging codes:
- 71260 CPT code – CT scan of the thorax with contrast
- 73721 CPT code – MRI joint imaging without contrast
Each code represents a different imaging modality and body region, which is why accurate coding is essential in medical billing services.
Billing Guidelines for 73718 CPT Code
Billing for this code requires strict adherence to payer policies and coding standards. Many healthcare providers rely on experts like Med Billing RES to manage these complexities efficiently.
Here are some key billing considerations:
- Verify patient insurance eligibility before the procedure
- Ensure prior authorization if required
- Use correct modifiers when applicable
- Avoid duplicate billing for the same session
- Confirm that documentation supports medical necessity
Failure to follow these guidelines can result in delayed payments or claim denials.
Common Mistakes to Avoid
Even experienced coders can make errors when billing for MRI procedures. Some common mistakes associated with the 73718 CPT code include:
- Confusing it with 73721 CPT code
- Missing documentation of “without contrast”
- Incorrect body part selection
- Lack of medical necessity justification
- Submitting claims without prior authorization
By outsourcing coding tasks to professionals like Med Billing RES, many practices reduce these errors and improve overall efficiency.
