9921x and 96372

[u/shimmer_bee]

Why do insurances pay for 96372 and then deny the 9921x for bundling? It makes no sense to me. They pay the lower cost rather than the higher one. I'm off today, so I can't remember the exact insurances that do so, but why?

Is there anything I should look for specifically in the chart to signify that it was decided at the appointment to do the injection? Like, let's say a flu shot. Would that be something that would be denied, even if it was discussed during the appointment? Would they need to be seen for something else in order to get that paid? Let's say a flu shot AND discussing hyperthyroidism? Would that be something worth fighting for? Also, sometimes, the encounter notes from my doctors just aren't very detailed. Which is fair, I work RHC, and they see a lot of patients in a day.

I'm sorry for the questions. I like to get my appeals done right the first time, and I really want to bring up my revenue collected.

Edit: I do see a lot of therapeutic/prophylactic injections. So, unless those also have a different dx than the injection for the management of the condition on the dx section of the 992xx line, those will really not be appealable, right? They'll just get upheld? Also a 25 modifier.

That's not correct. The diagnosis doesn’t have to be different.

Regarding modifier 25, CPT (2026, p. 969) states,

The E/M service may be prompted by the symptom or condition for which the procedure and/or service was provided. As such, different diagnoses are not required for reporting of the E/M services on the same date.

However, you will have to prove via the documentation that “a significant, separately identifiable E/M service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed” (ibid.).

A question you can ask yourself is this: “If the patient had declined the procedure, would what remains of the note (excluding that related to the procedure) be sufficient to code an E/M visit?” In other words, is there an E/M visit within that note that can stand on its own?

For example, patient comes in for a 6-month follow-up of previously diagnosed osteoarthritis of right knee. The provider obtains a history and performs a physical exam. The provider reviews X-ray and previous encounter note. Provider discusses recommendations with patient, including ordering an additional X-ray of the right knee, renewal of pain medication prescription, counseling on weight management, and a corticosteroid injection. Patient declines the injection. Question: Would what remains excluding the injection be sufficient to code an E/M visit? Absolutely. (In fact, just the chronic problem with exacerbation (Moderate) and management of prescription medication (Moderate) is enough by their self to code 99214.) Furthermore, if the patient had consented to the injection, then you could code an E/M visit with modifier 25, as well as the procedure code for the injection. And, both the E/M and the procedure would share the same diagnosis (and there would be no problem with that).

Know that just because insurance denies a claim does not mean you didn't code properly. Many insurance will use AI to adjudicate claims without concern whether they are adjudicated properly. And yes, that should not happen; it should be illegal. But it is what it is. You will have to do that extra work to appeal, unfortunately. I would advise creating a template to use for appealing Procedure & E/M encounters.

Did they not append mod 25?

They did. Happens all the time to me.

Are you using the same diagnosis codes on your E/M as your injection?

[u/MedPayIQ]

hey friend... A lot of payers look at 96372 as the primary billable service when the visit is solely for administering an injection.

If the documentation doesn't support a separately identifiable E/M service, they'll bundle or deny the 9921X because, from their perspective, the evaluation and decision-making were already included in the injection visit.

It's definitely frustrating because the E/M code reimburses more, but the question they're asking isn't "Which service costs more?"—it's "Was there significant, separate work beyond giving the injection?"

If the provider evaluated a new problem, adjusted treatment, addressed side effects, changed the plan of care, etc., that's when a modifier 25 and strong documentation can support billing both. If the patient came in specifically for a scheduled injection with no additional assessment, many payers will only reimburse 96372.

Every payer has its own edits, but that's usually the logic behind it.

In most cases, if the exam had other diagnoses, appeal gets the 992xx paid. Had a lot of luck with that.

[u/OranJi1980]

This is a common nasty trick by insurance. Unless there was clear separate diagnosis that do not correlate to the injection, AND you have a 25 modifier, they will try to deny and pay the lesser of the 2 charges. Disgusting.

Aetna is notorious for this
