Data - Tests of the Same "Type" Only Counted ONCE?

[koster.kris@yahoo.com]

I'm being told tests of the same "type" such as Radiology, can only be counted ONCE for Category 1 (Tests, Documents, Orders, Independent Historians). I've read all CPT guidelines regarding the amount/complexity of data many times over, and do NOT think this is correct. The only time I've counted several tests as ONE data element is when the tests are from one external source (each external source is counted once), OR labs with overlapping elements, such as CMP and Electrolyte panel = 1 test since electrolyte panel is included in CMP.

I'm coding for the ED physician in this case. Patient fell and has pain in her left upper extremity. X-rays of the left elbow, left forearm, and left wrist were taken. Here is the relevant documentation (in purple):

LABS, X-RAYS, AND EKG

Lt Elbow X-ray: (FINDINGS: Multiple views of the elbow show a fracture-dislocation. The ulna and radius are displaced posteriorly relative to the humerus. A fracture fragment is seen which may be part of the radial head and may also be part of the olecranon. There are fracture fragments just superior to the humeral condyles and in the joint space of the ulna and inferior to the humeral condyles.
IMPRESSION: Elbow fracture-dislocation.
Electronically signed by [Radiologist]
The X-rays were interpreted by the radiologist. Prior films were not available for comparison.

Lt Forearm X-ray: (FINDINGS: 2 views of the forearm again show an elbow fracture-dislocation. This is better described on the elbow films. The shafts of the ulna and radius appear intact.
IMPRESSION: Elbow fracture-dislocation.
Electronically signed by [Radiologist]
The X-rays were independently viewed by me and interpreted contemporaneously by me. The X-rays were interpreted by the radiologist. Prior films were not available for comparison.

Lt Wrist X-ray: (FINDINGS: Multiple views of the left wrist show normal bone density and alignment. No fractures demonstrated. Articular spaces are maintained.
IMPRESSION: No acute bony injury.
Electronically signed [Radiologist]

Course of Care: Patient is a female presents with left elbow/forearm pain after a mechanical fall. Slight abrasion to forehead, no LOC, headache, mental status changes.
Patient did not have chest pain, dizziness, difficulty breathing at any point.
Tenderness to forearm, particularly at elbow. NVI distally.
X-rays show fx dislocation at elbow.
Conscious sedation provided, elbow successfully reduced and splinted. NVI after procedure.
Patient will follow-up with ortho, will return if worse in any way.
Patient counseled in person regarding the patient's stable condition, test results, diagnosis and need for follow-up.
Medication administered under direct supervision of physician; IV fluid administered under direct supervision of physician for 1 hour or less.
Disposition: Condition: good and stable. Discharged.

CLINICAL IMPRESSION
Left radial head fracture and left olecranon fracture.
Dislocated left elbow with reduction in ER, associated with radius fracture.
Fall.
INSTRUCTIONS
Wear simple sling until released. Wear splint for one week. Return for worsening pain or if worse in any way. (Otherwise, follow-up with orthopedics as discussed.).

My calculation for amount/complexity of Data:
3 unique tests ordered (X-ray of elbow, X-ray forearm, X-ray wrist) (satisfies Category 1), +
1 Independent Interpretation (not separately reported) (satisfies Category 2)
= Extensive

I'm being told this is wrong, and was sent an email (red text) stating:

For E/M Medical Decision Making (MDM), CPT guidelines do not count data based on the number of CPT codes, but rather by category of data.
For Amount and/or Complexity of Data, tests are grouped into categories. Specifically:

• Category 1 includes “Tests, documents, orders, or independent historian(s)”
• Within Category 1:
  
  • Multiple tests within the same CPT-defined group (e.g., radiology) are counted as ONE element, regardless of how many individual studies are performed.

X-ray of elbow, X-ray of Forearm, and X-ray of wrist each have separate CPT codes, but they all fall under: Radiology (X-ray studies) → Counts as ONE Category 1 element
Independent interpretation of X-ray → adds ONE additional element

Total Data Calculation​

• Radiology tests (same category) → 1
• Independent interpretation → +1

Total = 2 elements → Moderate Data (NOT Extensive)

In this case, why does it matter? Extensive for data still would not get you to a higher code level.

But, in any case, YOU are correct and whoever gave you that guidance made it up. It is not present in either CPT, CPT-A, or CPT Knowledge Base that I could see.

The CPT book says:
"Test: Tests are imaging, laboratory, psychometric, or
physiologic data. A clinical laboratory panel (eg, basic
metabolic panel [80047]) is a single test. The
differentiation between single or multiple tests is defined
in accordance with the CPT code set. For the purpose of
data reviewed and analyzed, pulse oximetry is not a test.
Unique: A unique test is defined by the CPT code set.
When multiple results of the same unique test (eg, serial
blood glucose values) are compared during an E/M
service, count it as one unique test. Tests that have
overlapping elements are not unique, even if they are
identified with distinct CPT codes. For example, a CBC
with differential would incorporate the set of
hemoglobin, CBC without differential, and platelet
count. A unique source is defined as a physician or other
qualified health care professional in a distinct group or
different specialty or subspecialty, or a unique entity.
Review of all materials from any unique source counts as
one element toward MDM."

That is inconsistent with the guidance you are being given. XR of the hand, wrist and elbow do NOT have overlapping elements, are performed and interpreted separately, and cover separate body parts.
And frankly, if a CBC, Blood Glucose and Lipid Panel are counted as three unique tests, three separate sets of X-rays surely can...

I would push back strongly on this and ask what they believe the source of that contention is.

Agreed that the concept of test "types" is not accurate. That would contradict AMA/CPT guidance and intent. It is not a CMS rule and I haven't heard of it for any commercial plans.

Also, coding that way won't minimize audit risk, if that's their concern.

In addition to asking for their source I would show them your CPT manual.

Thank you so much for this reply. To answer your question of "why does it matter?" I'm completing AAPC's Practicode program, and this is coming from the coaches/instructors. If I follow their advice, it would change the way I calculate the MDM in other cases. Most importantly, I'm concerned I'm learning it WRONG.

I have pushed back strongly, asking them to show me ANY source from CPT/AMA/CMS where this concept is explained. They could not do so. They wrote back, reiterating their previous email--all X-rays fall into the same "group" regardless of how many x-ray studies there are.

So, I emailed them part of an article from Healthcare Business Monthly from May 2026. It's an FAQ for calculating the amount/complexity of data. Here is a relevant excerpt:

Q: Let’s say the physician has ordered several different labs (e.g., a CMP, a hepatic liver function panel, and thyroid panel). These are all blood tests. Do they count as three individual data points for each test ordered?

A: The guidelines state, “A unique test is defined by the CPT code set.” But the guidelines also state, “Tests that have overlapping elements are not unique, even if they are identified with distinct CPT codes.” The key is to know whether the tests are truly unique. In your example, a comprehensive metabolic panel (CMP) and a hepatic liver function panel have overlapping elements; the thyroid panel does not. Therefore, you would count two unique tests.

Then they changed their made-up "Radiology Category" theory, and used this "overlapping" guideline to say:
Elbow and Forearm X-rays overlap, so they're combined = 1 Tests
Wrist X-Ray = 1 Test
Total of 2 Tests.

Here is their reply (once again in RED):

Think of “unique tests” in MDM the way CPT intends—not as “how many images were taken,” but as how many truly distinct pieces of diagnostic information were generated.
CPT says a unique test is defined by the CPT code set, but it also adds an important qualifier: tests that overlap in what they evaluate are not considered unique, even if they have different CPT codes. That’s the part that trips people up.

In your scenario, although three X-rays were performed (elbow, forearm, wrist), you have to ask: Are these giving separate, independent clinical information, or are some essentially evaluating the same injury?

The elbow and forearm X-rays are both centered on the same traumatic event and overlapping anatomy. The forearm study largely reiterates the elbow fracture-dislocation already identified. Because of that overlap, CPT guidance supports counting them as one unique test, not two.
The wrist X-ray, however, evaluates a different anatomic area with a different clinical question (rule out wrist injury), so that does count as a separate unique test.
So instead of counting “three X-rays,” you’re really counting two unique tests from an MDM standpoint.

This is exactly the same logic used in the article example: even though multiple labs are ordered, if they share overlapping components, they don’t each count separately. The goal is to avoid inflating data just because multiple variations of the same evaluation were performed.

This still doesn't make sense to me (and if this was correct, why didn't they say that in the first place?)

The Data element should capture the physician work, including the medical decision making required to order appropriate tests. Even if the fracture-dislocation was evident on both studies, that doesn't mean the tests should be lumped together.

The physician could have ordered only the elbow and wrist, but he/she ordered the forearm for a reason--typically to rule out injury to the SHAFT of the radius and ulna--which would not be seen on x-rays of the elbow or wrist.

The elbow series is all about the JOINT, and includes special "trauma views" when a fracture is suspected. The documentation for the findings of each x-ray series demonstrates this.

Is there anyone I can reach out to who could provide a definitive answer to this (one that why would listen to)?

THANK YOU to anyone who has read this far. I'm so frustrated that I'm learning to code incorrectly from a program that's supposed to help strengthen my coding skills.

To clarify, you are being asked to code the pro-fee ED physician charges, not the ED facility, correct?

That is 3 tests/XR/orders. They do not overlap. I disagree with the direction you are being given. You are not wrong.

We don't code by misinterpreted guidance, "so & so told me to do XYZ", or AAPC Healthcare Business Monthly Articles. I understand what the individual is trying to say, but it is not correct. Using the lab example doesn't correlate to the XR in this example. The lab example they are talking about is where you can't separately count the hepatic (80076) because it is included in the CMP (80053). That is correct and aligns with the coding of panels from a lab standpoint. They are incorrectly trying to use that same thinking for the XR issue. I get what they are saying that you wouldn't count the # of images, as in, if the XR was a complete view, minimum of 3 views and a coder tried to count that single XR as 3 due to the views. I also (kind of) see where they are trying to come from in that the forearm and elbow "overlap" because in the example, the commentary and documentation of the forearm just reiterates the elbow. However, this is still a unique test (order/CPT).
