Modifier -25 (E/M): Significant, separately identifiable E/M on the same day

Quick reference

  • What it signals (Medicare): Use modifier -25 on the E/M code when, on the same date as a procedure/other service, the patient’s condition required a significant, separately identifiable E/M service beyond the usual pre-/post-work included in the procedure.
  • Same vs different diagnosis: Medicare allows the E/M and the procedure to be related to the same or different diagnosis; different diagnoses are not required.
  • Most common setting pattern: Same-day office/outpatient E/M + minor procedure, where the E/M is above-and-beyond the inherent procedure work.

Core Medicare rules (high yield)

  • Minor procedures (000/010): CMS states that if a procedure has a global period of 000 or 010, it’s considered a minor surgical procedure, and E/M services on the same date are generally included in the procedure payment (including the decision to perform the minor procedure).
  • When -25 is valid: A significant and separately identifiable E/M service that is unrelated to the decision to perform the minor procedure may be separately reportable with modifier -25.
  • New patient isn’t enough: CMS explicitly notes that being a new patient is not sufficient by itself to justify billing an E/M on the same day as a minor procedure.
  • Global surgery tie-in: CMS reiterates that minor surgery/endoscopy same-day visits are included in the global package unless the provider performs a significant, separately identifiable E/M service (billable with -25).

Documentation checklist (what to show)

  • Two distinct “stories” in the note: Document the E/M as a discrete assessment and plan (history/exam/MDM or time), and document the procedure separately (consent, technique, findings, complications, disposition).
  • Show “above and beyond”: CMS emphasizes not billing an E/M for the inherent pre-, intra-, and post-procedure work that is already built into minor and XXX global-indicator procedures.
  • Don’t force an unrelated diagnosis: CMS states the E/M and procedure do not need different diagnoses, so your documentation should focus on why the E/M was separately identifiable rather than inventing a second diagnosis.

Audit-friendly sentence starters (adapt to your chart):

  • “In addition to performing the procedure, I evaluated and managed _______ (separate problem) requiring additional history/exam/MDM; plan includes _______.”
  • “The E/M service addressed _______ and resulted in a separate management plan; this work was separate from the usual pre-/post-procedure care.”

Specialty examples (ophthalmology + ENT)

Ophthalmology patterns (CMS example is very useful)

  • CMS gives a specific example in ophthalmology: examining both eyes at the time of an intravitreal injection is not automatically separately identifiable, but if a fellow-eye evaluation reveals a new diagnosis requiring a new management plan, Medicare may consider it separately identifiable (supporting E/M with -25).
  • CMS also states intravitreal injections are treated as a minor surgical procedure, so the default expectation is that same-day E/M is bundled unless the E/M is significant/separately identifiable.

ENT “same-day E/M + procedure” (documentation pattern)

  • Use -25 when you truly do a separate problem-oriented E/M that goes beyond the pre-/post-service work of the ENT procedure (e.g., a full sinonasal complaint workup plus a separately performed in-office procedure).
  • Avoid -25 when the “E/M” is essentially only the minimal pre-procedure assessment, consent, and post-procedure instructions (that’s typically inherent).

Medicare payment “gotchas” (very common)

  • G2211 interaction (big in 2025+): CMS states that, except for AWV, vaccine administration, and Medicare Part B preventive services, they generally don’t pay HCPCS G2211 when the base O/O E/M is billed with modifier -25.
  • Exception CMS added: Beginning Jan 1, 2025, CMS allows billing G2211 when reporting an O/O E/M (99202-99205 or 99212-99215) with -25 on the same day as an AWV, vaccine administration, or any Medicare Part B preventive service.
  • Denial risk: If your E/M documentation doesn’t clearly exceed the inherent minor-procedure work, the -25 E/M line is a common denial/audit target because CMS expects the procedure-day visit to be bundled unless separately identifiable.

Quick self-check (before you append -25)

  1. Did you create a separate assessment + plan that required additional work beyond the procedure’s usual pre-/post-care?
  2. Is the E/M not just the decision to do a minor procedure (000/010) and not just routine pre-op/procedure-day work?
  3. If audited, can the note stand alone showing why the E/M was significant/separately identifiable—even if it’s the same diagnosis as the procedure?
