When can you bill an office visit with modifier 25 on the same day as a minor procedure?
Bill the office visit with modifier 25 when the note shows real work on a problem beyond deciding on and doing the procedure. Here is a joint injection note, line by line, and the claim it supports.
By Alex, Chief Medical Officer
You can bill an office visit on the same day as a minor procedure when the note shows significant work on a problem beyond deciding on and doing the procedure. Put modifier 25 on the office visit code, never on the procedure code, and make sure anyone reading the note can point to that separate work.
Modifier 25 is the two-character tag that tells the insurance company the visit was its own service. Medicare already pays for the decision to do a minor procedure, the usual check beforehand and the care right after, inside the procedure's payment. So every same-day claim comes down to one question. What else did the clinician evaluate and manage today?
What does Medicare already pay for inside a minor procedure?
Every procedure has a global period, meaning the days of related care that are bundled into the procedure's payment. Medicare treats a procedure as minor when its global period is 0 or 10 days. In Medicare's 2026 fee schedule file, a large joint injection without ultrasound (20610) has 0 days. Removing up to 15 skin tags (11200) and destroying up to 14 benign lesions such as warts (17110) have 10.
For those procedures, the payment covers deciding to do it, the usual work before and after, and the procedure itself. A new patient doesn't change that. Neither does the fact that the patient had to be examined before the injection.
A second diagnosis isn't required. CMS allows the office visit and the procedure to share a diagnosis, as long as the visit work stands apart from the procedure.
This table turns the 2026 Medicare NCCI manual's global surgery and modifier rules into a chart question. It's Medicare's rule; check your other payers' policies.
| Same-day situation | What the Medicare rule says | What to check in the chart |
|---|---|---|
| Minor procedure with a 0- or 10-day global period | The decision to do it and the usual procedure work are included. Modifier 25 can mark a significant, separately identifiable office visit beyond that decision. | Can a reader find the extra visit work without counting the procedure's own work again? |
| Procedure with global indicator XXX, meaning the global surgery rules don't apply | The procedure's built-in work before, during and after isn't billable as a visit. A significant visit above that work may qualify for modifier 25. | Is the visit more than supervising the procedure or reading its result? |
| Major procedure with a 90-day global period | A same-day visit to decide on major surgery is reported with modifier 57, not 25. Other pre-surgery visit work is included. | Was this the decision for major surgery, or a separate problem? |
What does a note that supports modifier 25 look like?
Here's a sample. A 68-year-old established patient is on the schedule for a steroid injection in her right knee, for osteoarthritis her doctor has followed for two years. She also mentions that her home blood pressure readings have been high for three weeks.
| Line in the note | Paid as | Why |
|---|---|---|
| "Right knee osteoarthritis. Pain on stairs is worse despite acetaminophen. Discussed injection risks and benefits, and she wants to go ahead." | The injection | Deciding to inject and the check before it are paid inside 20610. |
| "Right knee prepped, injected with triamcinolone 40 mg and lidocaine, lateral approach. Tolerated well. Ice tonight." | The injection | This is the procedure and its usual aftercare. |
| "Hypertension. Home readings 148 to 156 over 90 to 96 for three weeks, 154/94 today, above her goal. Increase amlodipine from 5 mg to 10 mg daily. Recheck in 4 weeks with her home log." | The office visit | A separate problem, evaluated and managed today, with a medicine change. |
That note supports three claim lines:
| Line | Code | Diagnosis it points to |
|---|---|---|
| 1 | 20610, large joint injection (add RT if the plan wants the side) | M17.11, primary osteoarthritis of the right knee |
| 2 | J3301 x 4 units, triamcinolone acetonide, 10 mg per unit | M17.11 |
| 3 | 99214 with modifier 25, established patient office visit | I10, essential hypertension |
The visit level comes from the blood pressure work alone. Under the AMA's medical decision making (MDM) rules, a chronic illness that isn't at the patient's goal counts as poorly controlled, which makes it a moderate problem. Changing the amlodipine dose is prescription drug management, which is moderate risk. Two moderate parts out of three support a 99214. The knee adds nothing to the visit level, because the injection payment already covers that thinking.
Now take the blood pressure lines out. The note describes a knee, a decision and an injection, so the claim is lines 1 and 2 and nothing more. At Medicare's 2026 national rates, before your local adjustment, a 99214 pays $135.61 and 20610 pays $68.81. A visit code on that note would bill $135.61 for work Medicare already paid inside the injection, and that's the claim auditors look for.
Most real notes sit between those two. "HTN stable, continue meds" shows another problem came up, and little else. The thinner the separate work, the harder it is to call it significant, so read that line the way a reviewer would before you add the visit.
Can you count time instead of medical decision making?
Yes, with one limit. The AMA's E/M rules say the total time for a visit doesn't include time spent on other services billed separately. The minutes spent prepping and injecting the knee belong to 20610 and can't count toward the office visit. If you're deciding which method fits, see how to choose between time and medical decision making.
Why doesn't the claim edit settle it?
CMS says not to add a modifier just to get past an NCCI edit, the automatic code-pair rules that bundle one service into another. The clinical facts have to justify it. A billing system that adds 25 whenever a visit and a procedure share a date has only read the claim, and the note is what an auditor reads.
What should you check before the claim goes out?
- Look up the procedure's global days. 0 or 10 means the decision to do it is already paid.
- Mark the lines that belong to the procedure: the decision, the consent, the procedure note and the aftercare.
- Find the separate problem that was evaluated and managed, and point the office visit line to its diagnosis.
- Level the visit on that separate work alone, by MDM or by time without the procedure minutes. What separates a 99213 from a 99214 walks through the levels.
- Put modifier 25 on the office visit code. For a same-day decision on a 90-day major surgery, the modifier is 57.
The same separate-work test applies when a problem comes up during an annual wellness visit.
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. Your team decides whether that work stands apart from the procedure, and a person makes every change in the chart.
