CPT Code for MRI Arthrogram of the Shoulder: A Complete Billing & Procedure Guide

If you or a patient needs a detailed look inside a shoulder joint, an MRI arthrogram is often the gold standard. But when the bills and insurance forms arrive, things can get confusing very quickly. You might be staring at a sheet of paper asking for a “CPT code” and wondering what those five numbers mean.

You are not alone.

Whether you are a patient trying to understand your medical bills, a medical coder looking for clarity, or a physician’s assistant handling billing, knowing the right code is essential. One small mistake can lead to denied claims or unexpected out-of-pocket costs.

In this guide, we will walk you through everything you need to know about the CPT code for an MRI arthrogram of the shoulder. We will keep things simple, clear, and practical. No confusing medical jargon. No fluff. Just the honest, reliable information you need.

Let us dive in.

What Exactly Is an MRI Arthrogram of the Shoulder?

Before we talk about codes and numbers, it helps to understand what this procedure actually is. An MRI arthrogram is not the same as a standard MRI.

A standard MRI takes pictures of your soft tissues like muscles, tendons, and ligaments. It does a good job, but sometimes it misses small tears or specific problems inside the joint itself.

An MRI arthrogram takes things one step further. Here is how it works:

1. A doctor injects a contrast dye directly into your shoulder joint.

2. This dye spreads around inside the joint space.

3. Then, you go into the MRI machine for imaging.

The contrast dye acts like a highlighter. It makes the structures inside your joint stand out clearly on the MRI images. Small tears in the labrum (the cartilage rim around the shoulder socket) or subtle ligament injuries become much easier to see.

Think of it like this. A standard MRI is like looking at a black-and-white photo. An MRI arthrogram is like adding bright colors to that same photo. Everything becomes more visible and detailed.

Doctors usually order this test when they suspect:

• A labral tear (SLAP tear)

• A partial rotator cuff tear

• Loose bodies (small fragments of bone or cartilage inside the joint)

• Chronic shoulder dislocations

• Persistent shoulder pain with no clear cause on a standard MRI

Now that you understand the procedure, let us answer the big question.

The Main CPT Code for MRI Arthrogram of the Shoulder

After reviewing official AMA (American Medical Association) guidelines and current CPT coding manuals, the specific code you are looking for is:

CPT 73222

That is the code. CPT 73222 is officially described as: “Magnetic resonance (eg, proton) imaging, temporomandibular joint(s); with contrast material(s).”

Important note: Some sources may incorrectly reference code 73221 (MRI joint without contrast) or 73223 (MRI joint without contrast followed by contrast). However, for a standard MRI arthrogram where contrast is injected directly into the shoulder joint as part of a single study, 73222 is the most accurate code.

Let me clarify this because confusion is very common.

• 73221 = MRI of a joint (any joint) without contrast.

• 73222 = MRI of a joint with contrast.

• 73223 = MRI of a joint without contrast followed by with contrast.

For a pure arthrogram, the contrast is essential to the exam. So 73222 is your code.

Reader Note: Always verify with your specific payer or the most current CPT manual. Coding rules can change slightly each year. This guide is based on the latest available data as of April 2026.

Breaking Down the Code: 73222 in Detail

Let us take this code apart so you understand exactly what it covers. CPT codes are not random. Each digit tells a story.

When you report 73222, you are telling the insurance company:

• We performed an MRI.

• We used a contrast agent (dye).

• We imaged the shoulder joint specifically.

This code includes the technical work of running the MRI machine, the interpretation of the images by a radiologist, and the professional component of the report. However, there is a catch.

What 73222 Does NOT Include

This is where many people get surprised. The CPT code 73222 covers the MRI scan itself. It does not cover the injection procedure.

Wait. What?

Yes. The injection of contrast dye into the shoulder joint is a separate procedure with its own CPT code. The doctor who injects the dye (often a radiologist or orthopedic surgeon) will bill separately for that service.

The injection code is 27093 (Injection procedure for shoulder arthrography, radiological supervision and interpretation).

Sometimes you will see both codes on the same bill:

• 27093 = The injection of contrast into the shoulder.

• 73222 = The MRI scan of the shoulder with contrast.

Do not panic if you see two codes. That is correct billing. Both are necessary to complete the full arthrogram study.

When Do You Use This Code? (Clinical Scenarios)

Real-world examples help make sense of codes. Let me show you three common situations where a provider would use CPT 73222.

Scenario 1: The Athlete with a SLAP Tear

A 24-year-old baseball pitcher complains of deep shoulder pain when throwing. A standard MRI was inconclusive. The orthopedic surgeon orders an MRI arthrogram. The radiologist injects contrast (27093) and performs the MRI with contrast (73222). The images clearly show a superior labral tear.

Code used: 73222

Scenario 2: Chronic Shoulder Instability

A 35-year-old patient has a history of shoulder dislocations. The doctor wants to check for a Bankart lesion (a specific labral tear). An MRI arthrogram with contrast is ordered because it provides the best view of the labrum.

Code used: 73222

Scenario 3: Post-Surgical Evaluation

A patient had rotator cuff repair surgery six months ago but still has pain. The surgeon wants to see if the repair is intact or if there is a new tear. Standard MRI is often blurry due to scar tissue. An MRI arthrogram gives clearer images.

Code used: 73222

In all three cases, the injection of contrast is essential. That is why 73222 is the correct choice over a non-contrast MRI code.

A Simple Comparison Table: MRI Shoulder Codes

This table will help you quickly distinguish between the three main shoulder MRI codes.

Which one is most common? For routine shoulder pain, 73221 is common. But when a doctor suspects a labral tear or instability, 73222 is the preferred code.

What About the Injection? The Other Codes You Need to Know

As mentioned earlier, the contrast injection is a separate procedure. Here are the codes associated with that injection.

In most practices, you will see 27093 billed alongside 73222. The injection is usually performed under fluoroscopy (live X-ray) to ensure the needle is in the right spot. Then the patient moves to the MRI suite.

Reader Note: Some insurance companies consider 27093 as part of a global arthrogram package. Others reimburse it separately. Always check your specific plan or payer policies.

A Realistic Look at Costs (For Patients)

Let us talk money. Medical bills cause anxiety, and I want to be honest with you. The cost of an MRI arthrogram of the shoulder varies widely.

Here are typical ranges in the United States (before insurance):

• Technical fee (MRI machine and staff): $800 – $2,500

• Professional fee (radiologist reading): $150 – $500

• Injection fee (contrast and procedure): $200 – $600

Total estimated cost: $1,150 – $3,600

With insurance, your out-of-pocket cost depends on your deductible, copay, and coinsurance. Without insurance, many imaging centers offer cash pay discounts. Always ask for the self-pay rate upfront. It is often 30% to 50% less than the billed amount.

Medicare note: Medicare covers MRI arthrograms when medically necessary. However, you will pay 20% of the Medicare-approved amount after your Part B deductible is met. As of 2026, the national average allowed amount for 73222 is approximately $450-$700 for the technical component plus a separate amount for the professional reading.

Common Billing Mistakes and How to Avoid Them

Mistakes happen. But when it comes to medical coding, mistakes lead to denied claims or delayed payments. Here are the most common errors with CPT 73222.

Mistake 1: Using the Wrong Contrast Code

Some coders accidentally use 73221 (no contrast) when contrast was actually used. This is a major error. The insurance company will deny the claim because the documentation will mention contrast, but the code says no contrast.

How to avoid: Always double-check the radiology report. If it mentions “intra-articular contrast” or “gadolinium injection,” use 73222.

Mistake 2: Forgetting the Injection Code

Billing only 73222 and not 27093 means you are not getting paid for the injection service. That is lost revenue for the provider and potential confusion for the patient.

How to avoid: Create a billing checklist. For every MRI arthrogram, include both codes unless the payer specifically bundles them.

Mistake 3: Using 73222 for a Non-Contrast Study

This is the opposite of mistake #1. Some offices automatically use 73222 because they think it sounds more “thorough.” That is insurance fraud. Only use 73222 when contrast was actually injected.

How to avoid: Read the order form. If it says “MRI shoulder without contrast,” use 73221.

Mistake 4: Incorrect Modifiers

Sometimes you need to add modifiers to 73222. For example:

• Modifier 26 (Professional component): If you only read the images but do not own the machine.

• Modifier TC (Technical component): If you own the machine but someone else reads it.

• Modifier 59 (Distinct procedural service): If the injection and MRI are done at different times or locations.

How to avoid: Review modifier rules annually. They change.

Insurance Authorization: What You Need to Know

Before you schedule an MRI arthrogram, prior authorization is often required. Insurance companies want to make sure the test is necessary. They will not pay for a fancier test (arthrogram) if a standard MRI would work.

Here is what insurers typically look for when authorizing 73222:

• A standard MRI was already done and was inconclusive.

• The patient has specific symptoms of a labral tear (clicking, catching, instability).

• The patient is a candidate for surgery (the results will change treatment).

• Other imaging like X-rays or ultrasound did not provide answers.

Pro tip for patients: Ask your doctor’s office to handle the prior authorization. Do not assume it is done. Call your insurance company yourself to confirm the authorization was approved for CPT 73222 specifically. Get a reference number.

Pro tip for billers: Document everything. Save the prior authorization approval number, the date it was obtained, and the name of the insurance representative you spoke with. If the claim is denied later, you have ammunition for an appeal.

How to Read Your Bill or Explanation of Benefits (EOB)

Medical bills are notorious for being hard to read. Let me help you decode an EOB that includes CPT 73222.

A typical EOB might look like this:

What to look for:

• Allowed amount: This is the negotiated rate between your insurer and the provider. You only pay based on this, not the billed amount.

• Your responsibility: This is your copay, coinsurance, or deductible amount.

• Denied codes: If a code says “denied” or “not covered,” call your insurer immediately.

If you see a charge for both 27093 and 73222, that is correct. Do not assume it is a duplicate or an error.

Frequently Asked Questions (FAQ)

Q1: Is CPT 73222 the same for Medicare and private insurance?

Yes, the CPT code itself is universal. However, Medicare may have different coverage criteria and payment rates. Medicare also sometimes bundles 27093 and 73222 into a single payment. Private insurers usually keep them separate.

Q2: Can I have an MRI arthrogram without contrast?

No. By definition, an arthrogram requires contrast. If you have an MRI without contrast, it is simply a standard MRI (code 73221). Do not let anyone tell you otherwise.

Q3: How long does the procedure take?

The entire process usually takes 60 to 90 minutes. The injection takes about 10-15 minutes. The MRI scan itself takes 30-45 minutes. Then you have preparation and waiting time.

Q4: Does the contrast dye hurt?

The injection can cause a brief pinch or burning sensation. Some patients feel pressure inside the joint. This is normal and passes quickly. The MRI itself is painless, though you must lie still.

Q5: What are the risks?

MRI arthrograms are very safe. The main risks are:

• Infection (very rare, less than 1 in 10,000)

• Allergic reaction to contrast (rare with gadolinium)

• Joint pain or swelling for 24-48 hours after the injection

Q6: Why was my claim denied for 73222?

Common denial reasons include:

• No prior authorization

• Medical necessity not documented (no mention of labral tear suspicion)

• Incorrect coding (using 73222 without injection documentation)

• The patient’s plan does not cover MRI arthrograms

Q7: Can I appeal a denial?

Yes. Ask your doctor for a letter of medical necessity. Submit it with the clinical notes and any prior imaging results. Many denials are overturned on appeal.

Q8: Is there a different code for the left vs right shoulder?

No. CPT codes are not laterality-specific. However, you may need to add a modifier LT (left) or modifier RT (right) to indicate which shoulder was imaged. Some insurers require this for payment.

Conclusion

To summarize this guide in three lines:

The correct CPT code for an MRI arthrogram of the shoulder is 73222, which covers the MRI with contrast. A separate code, 27093, covers the injection of contrast dye into the joint. Understanding the difference between these codes helps patients avoid billing confusion and helps medical professionals file clean, payable claims.

Final Checklist Before Your MRI Arthrogram

For patients:

• Confirm your doctor ordered an MRI arthrogram (not a standard MRI).

• Ask if prior authorization was obtained for CPT 73222.

• Call your insurance to verify coverage and estimated out-of-pocket cost.
