G2211 vs no G2211 (when to add)

G2211 is the Medicare add-on for longitudinal-care visit complexity. Add it when the practice is the continuing focal point; omit on discrete, one-off visits.

Last reviewed May 24, 2026

Side by side

Option A

Add G2211

Visit complexity add-on for office/outpatient E/M associated with ongoing care of a single, serious, or complex condition, or for a practice that is the continuing focal point for all needed services.

HCPCS G2211

Add-on to office E/M (99202–99215).
Reimbursed by Medicare; commercial payer policy varies.
Does not apply when an E/M is reported with modifier 25 (per CMS policy).

Option B

Do not add G2211

Omit G2211 when the visit is for a discrete, time-limited acute problem with no expectation of continuing focal-point care, or when modifier 25 is appended to the E/M.

—

Acute urgent-care-style visits typically do not qualify.
Same-day E/M-plus-procedure with modifier 25 currently disqualifies G2211.

Skip G2211Single-encounter problem, no ongoing relationship documented

When to use Add G2211

Established patient with multiple chronic conditions managed by the practice over years.
Single serious condition (e.g., metastatic cancer) managed by the practice as the continuing focal point.

When to use Do not add G2211
