Billed Does Not Mean Defensible: Modifier 25 and Same-Day Podiatry Care

Same-day care is normal in podiatry. A patient comes in for a worsening diabetic foot, a painful nail, or a wound that looks different than it did last month. You evaluate the problem. You also treat it in the same visit: a debridement, a nail procedure, or an injection.

Two distinct services may have taken place, and separate billing may be appropriate. But appropriate is not the same as defensible. The question a payer asks later is not whether the patient needed care. It is whether your chart shows that the evaluation stood on its own, apart from the procedure.

That is the Modifier 25 question. And for many same-day podiatry claims, it is where the claim quietly gets weak.

The audit signal is real, and worth reading carefully

In a report posted in December 2025, the HHS Office of Inspector General reviewed podiatrists' E/M claims billed with Modifier 25. Of 100 sampled claims, 44 did not comply with Medicare requirements. OIG estimated that roughly $39.6 million of the $222.5 million Medicare paid over the audit period may not have complied, and CMS agreed to look at whether more oversight was needed. (1)

That is a signal you should not ignore. It is also one you should not over-read.

The American Podiatric Medical Association pushed back on the framing, and fairly. Podiatrists routinely perform a procedure and a significant, separately identifiable evaluation at the same encounter, which is normal, appropriate care. APMA also noted the audit used 2019 data, and that sample-based extrapolations can overstate the real exposure. (2)

Both things are true at once. Same-day E/M is frequently justified. And a justified service can still fail as a claim if the separate work never made it into the note.

That gap, between what happened and what the record shows, is the practical problem. It is also the one you can do something about.

The goal is not to make podiatrists more defensive. The goal is to make the billing story easier to defend before the claim leaves.

The same-day visit is not the problem

The most common mistake here is treating the timing as the risk. It is not. There is nothing wrong with evaluating and treating a patient on the same day.

The risk is narrower: whether the evaluation has its own support in the chart, separate from the procedure.

A defensible same-day E/M usually answers a few plain questions. What new or worsening problem did you evaluate? What history, exam, or decision-making happened beyond the work any procedure normally includes? Does the note make that separate work visible?

If the answer lives only in your memory of the visit, the claim is exposed. The payer does not review your memory. It reviews the record.

The modifier is a signal, not a defense

Modifier 25 tells the payer that an E/M was significant and separately identifiable from another procedure or service performed on the same day. In many podiatry encounters, that means the separate evaluation has to stand apart from the usual work associated with the procedure. (1)

But the modifier only makes the claim. It does not prove it. The proof is in the documentation.

Picture two versions of the same visit. In the first, the note details the nail procedure and adds a line that the patient was seen for an ingrown nail. In the second, the same procedure note also records that the patient reported new numbness, that you checked sensation and pulses, reassessed diabetic risk, and adjusted the plan. Same day, same procedure. Only the second note shows an evaluation that can stand on its own.

When the chart separates the evaluation from the procedure, the modifier is backed by something. When it does not, the modifier is an assertion the record cannot support, and that is the kind of claim an auditor or payer reviewer may pull.

Where same-day podiatry claims get fragile

Podiatry carries a layer most specialties do not: coverage logic often sits right next to the modifier. A single encounter can touch routine foot care exclusions, a systemic-condition pathway, the class findings behind Q7, Q8, or Q9, active-care rules, and frequency limits. Any one of those can raise its own question. (3)

You do not need to resolve all of that here. The point is narrower: a podiatry claim can look simple on the line and be complicated underneath, and the same-day E/M is often the first place that complexity surfaces.

That is why it is the right place to start.

Routine foot care and the Q modifiers deserve their own treatment. That is a separate conversation.

What to check before a same-day claim leaves your office

Whether you bill in-house or work with an outside partner, a same-day E/M and procedure claim is worth a quick look before it goes out.

The useful question is not "can we bill this?"

What would we point to if someone asked?

Before the claim leaves, can you answer:

  1. What did you evaluate that was separate from the procedure?
  2. Where in the note is that separate history, exam, or decision-making visible?
  3. Does the documentation distinguish the evaluation from the procedure work?
  4. Does the procedure itself have its own support?
  5. Does the claim, as coded, match what the record can actually defend?
  6. Is the right move to release it, revise it, hold it, or clarify the note while the visit is still fresh?

Most claims clear those questions easily. The ones that do not are the ones worth touching before they leave, not after a denial or a records request.

Why a retrospective review is the safest first move

You do not have to change how you work to find out where you stand.

The lowest-risk starting point is a bounded review of claims you have already submitted. Take a small set, look at what the chart and the claim appeared to support, and compare that against the claim outcome: paid cleanly, denied, reduced, or pulled for records.

You are not relitigating old claims. You are looking for patterns: same-day E/M claims where the separate work was clearly documented, and the ones where it was thin. Procedures better supported than the evaluation beside them. Claims that paid despite weak notes, which is its own kind of risk, because it builds a habit no one is checking.

That is how a practice moves from "we think our documentation is fine" to actually knowing which claims are worth a second look before submission.

The same defensibility gap shows up in other specialties, including same-day urology visits and cystoscopy-related claims, where clinical appropriateness and billing support can diverge.

Where CodeGuard fits

The CodeGuard synthetic demo illustrates a possible window after a note and draft claim exist but before claim release. It is not a delivered customer workflow.

It does not replace whoever handles your billing. It does not decide whether care was appropriate. That is your call.

It flags which claims may be fragile, why, and what record or coverage support to check before submission.

For a same-day podiatry claim, that means looking past whether Modifier 25 is present to whether the chart behind it holds up.

That is the difference between a claim that is merely complete and one that is defensible.

A practical starting point

Orchid is preparing bounded retrospective reviews for podiatry practices. No workflow change and no EHR integration are required to begin. The first step is a review of already-processed claims to see whether recurring patterns were visible earlier, while they were still easier to address.

If your practice keeps running into questions around Modifier 25, same-day E/M support, nail procedures, debridement, or payer records requests, that small review is the safest place to start.

The modifier is not the defense. The chart is.
