When do test results count as data for office visit MDM?

Count each unique test once, at the visit where it was ordered, and each outside source's records once. A metabolic panel is one test, not fourteen numbers.

A test result counts as data once, at the visit where the test was ordered, or at the visit where it's analyzed if it was ordered outside a visit. Count each unique test, not each number on the screen, and count records from each outside doctor or facility once.

Data is one of the three parts of medical decision making (MDM), the method that sets most office visit levels. The other two are the problems addressed and the risk of the treatment chosen. A visit's level is set by two of the three, so a miscounted data column can move a visit up or down a level.

What counts as one test?

The AMA defines a test by the CPT code set. A lab panel, like a comprehensive metabolic panel (80053), is one test, even though it prints 14 values. Comparing several results of the same test, like a run of blood sugars, is one test. Tests that overlap are one test even when they have different CPT codes; the AMA's example is a CBC with differential, which already includes the hemoglobin and platelet count.

The AMA also says a test ordered during a visit is presumed to be analyzed when the result comes back, so it counts at the visit where it was ordered. Reviewing that result at the next visit doesn't count it a second time. A test ordered outside a visit, say from a portal message between appointments, counts at the visit where the clinician analyzes it.

Outside records count by source. Everything you review from one outside doctor, group or facility counts as one element, however many pages it runs.

How do you count the data for a real visit?

Here's a sample follow-up for a 66-year-old with type 2 diabetes and high cholesterol. The chart shows:

What's in the chartCountsWhy
Comprehensive metabolic panel (80053), ordered today1A panel is one test, counted at the visit where it's ordered.
Basic metabolic panel (80048), also on today's order from a template0Every part of it is inside the comprehensive panel, so it overlaps.
Lipid panel (80061), ordered today1One unique test.
Hemoglobin A1c (83036), ordered today1One unique test.
TSH result, from a test ordered at her last visit0It was counted at the visit where it was ordered.
Cardiology consult note from her heart doctor's practice, reviewed today1Review of external notes from one unique source.
The 25 or so numbers across those lab screens0 extraValues inside a test don't count on their own.

Counting rows would give this visit more than 25 data points. Counting tests and sources gives four.

How many data elements make limited or moderate?

The AMA's MDM table sorts data into categories. Category 1 covers tests, documents and independent historians, meaning someone like a spouse or caregiver who gives history because the patient can't give a complete one.

Data levelWhat it takes
Limited, for low MDMAny 2 from category 1: notes from each unique outside source, the result of each unique test, the ordering of each unique test. Or an assessment that needs an independent historian.
Moderate, for moderate MDMAny 3 from category 1, now including the independent historian. Or your own interpretation of a test another clinician performed, when you don't bill that interpretation separately. Or a discussion of management with an outside clinician.

The sample visit has four category 1 elements, so its data is moderate. Data alone doesn't set the level, though. If the note also shows that her diabetes and cholesterol were each assessed and both are at goal, that's two stable chronic illnesses, a moderate problem. Moderate problems plus moderate data support a 99214 even if the plan only continues her medicines.

What can't be counted?

One rule catches practices that bill their own in-office tests. When the same clinician separately bills a test's professional component, like the interpretation of an in-office ECG (93000), that test can't also count as data ordered, reviewed or interpreted for the visit. The ECG gets paid on its own line.

Pulse oximetry doesn't count as a test for MDM. A referral with no evaluation of your own doesn't make a problem addressed. And a problem that's only on the problem list, with no assessment today, doesn't add to the problems column, however many labs are attached to it.

What should the note say so the data counts?

Write the tests into the assessment and plan, tied to the decision they inform. "CMP, lipid panel and A1c ordered to monitor diabetes and statin therapy" counts three tests in one line. "Reviewed cardiology consult note from 10/14, no change to aspirin" shows the outside source was used. A lab section pasted at the top of the note shows the numbers exist, and a biller still can't tell what the clinician did with them.

Data is one of three parts. For the risk part, see when a refill counts as prescription drug management. For the level as a whole, see 99213 vs 99214, and for visits where time is the better method, time or medical decision making.

Cortex Lens reads each note in Practice Fusion before it's signed and shows the visit level its medical decision making supports, 99212 to 99215, up or down, with what would support the next level. Your team decides, and a person makes every change in the chart.
