Documentation requirements

What must appear in the operative or office note to support the claim.

Source · Editorial brief grounded in 5 cited references ↓

  • Total time in minutes documented, including non-face-to-face work performed on the date of service, if billing by time
  • Medical decision-making level documented with problems addressed, data reviewed, and risk assessment if billing by MDM
  • Established patient status confirmed — patient must have been seen by a provider in the same group/specialty within the past 3 years
  • Assessment and plan specific to the presenting problem(s), not a generic template entry
  • If modifier 25 is used, the note must clearly show the E&M service was separate and distinct from any procedure performed that day
  • Diagnosis codes that support the complexity level billed — a single stable chronic condition typically aligns with low-complexity MDM

What this code covers

Source · Editorial summary grounded in 5 cited references ↓

99213 is the go-to E&M code for established patient follow-up visits involving a stable chronic condition or a straightforward acute problem. Billing is supported by either total encounter time of 20–29 minutes (face-to-face plus same-day work such as ordering, reviewing results, and documentation) or by meeting the threshold for low-complexity medical decision-making. You don't need both — one qualifying element is sufficient under post-2021 E&M guidelines.

In orthopedic practice, 99213 fits post-op visits outside the global period, straightforward medication or DME follow-ups, and injury rechecks where the clinical picture is stable. When a procedure — injection, I&D, minor soft-tissue work — is also performed on the same visit, append modifier 25 to 99213 to establish that the E&M was a separate, significant service. Without modifier 25 in that scenario, expect a bundling denial.

Documentation must reflect the level you're billing. A note that lists vitals and a one-line assessment won't support 99213 if you're billing on MDM — the note needs to show the problems addressed, data reviewed, and risk of complications or treatment. Payers, including Medicare, audit coding patterns against specialty benchmarks, so a practice billing 99213 for every established visit invites scrutiny just as much as one that never uses it.

Common denial reasons

The recurring reasons claims for CPT 99213 get rejected.

Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓

  • Missing or insufficient documentation of total time when billing on a time basis — 'approximately 20 minutes' without specifics invites downcoding
  • Modifier 25 absent when 99213 is billed same-day as a procedure, triggering automatic bundling denial
  • Upcoding pattern flagged by payer when 99213 is billed for visits whose notes reflect only minimal complexity
  • New patient billed as established — if no provider in the group has seen the patient in the past 3 years, use 99203 instead
  • Time-based billing counting only face-to-face time rather than total encounter time, falling short of the 20-minute threshold

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 5 cited references ↓

01Can I bill 99213 based on time alone, without documenting MDM?
Yes. Under the 2021 E&M guidelines, time is a standalone billing basis. Document total time spent on the encounter that day — face-to-face plus any same-day work like reviewing results or writing referrals — and if it lands in the 20–29 minute range, 99213 is supported. You don't need to also satisfy MDM criteria.
02When does 99213 require modifier 25 in orthopedic practice?
Any time you perform a separately billable procedure — joint injection, aspiration, wound care, splint application — on the same date as the E&M, append modifier 25 to 99213. The modifier signals that the visit involved significant evaluation work beyond what's inherent in the procedure. Document the distinct clinical decision-making in the note.
03How does 99213 differ from 99212 and 99214?
99212 covers 10–19 minutes or minimal MDM. 99213 sits at 20–29 minutes or low MDM. 99214 requires 30–39 minutes or moderate MDM. In orthopedics, 99214 is more appropriate when you're managing a worsening condition, interpreting imaging, or adjusting a complex treatment plan. Defaulting to 99213 for all follow-ups when notes reflect moderate complexity leaves reimbursement on the table.
04Does the 99213 global period affect billing during post-op care?
99213 carries a global period of XXX, meaning the code itself has no global period — there's no procedure-linked restriction on the E&M code. What matters is whether you're inside the global period of a surgery you performed. If the visit is within the global window of a procedure with a 10- or 90-day global, bill the follow-up with modifier 24 to show the visit is unrelated to the surgical diagnosis, or expect it to be denied as included in the global.
05Can 99213 be billed for telehealth visits?
Yes, Medicare and most major payers allow 99213 for audio-video telehealth encounters. Confirm the patient's location and provider's location meet payer eligibility rules, document the encounter the same way you would in person, and apply the appropriate telehealth modifier per your payer's requirements. Audio-only visits have more restricted coverage — check payer-specific rules before billing.
06Is 99213 ever appropriate for a new patient?
No. 99213 is restricted to established patients. If no provider in your group practice (same specialty) has seen the patient within the past 3 years, use the new patient series starting at 99202. Billing 99213 for a new patient is a compliance risk and a common audit finding.

Mira AI Scribe

Mira's AI scribe captures total encounter time (including chart review, ordering, and post-visit documentation), the specific problem(s) addressed, MDM elements (data reviewed, risk level, number and complexity of problems), and any procedures performed the same day. That prevents the two most common 99213 denials: time underdocumented when billing by the clock, and a missing modifier 25 justification when a procedure runs concurrent with the E&M.
