The questions physicians actually ask, answered in one screen: the verdict, the rule, and the exact phrase your note is missing.
G2211 is blocked with modifier 25 on ordinary procedure visits such as injections. CMS carved out exceptions for certain preventive services, including the annual wellness visit and vaccine administration, when its criteria are met. On ordinary injection days the add-on drops; on visit-only days for a patient whose ongoing care you own, it belongs on every claim.
Assessing the joint you inject is part of the injection. The visit is separately reportable with modifier 25 only when the note shows distinct work: another problem managed in its own right, or genuinely separate evaluation beyond the procedure decision.
Closed treatment without manipulation codes exist for exactly this, and they carry a 90 day global. The alternative is coding each visit as E/M instead; the better choice depends on expected follow up, and either is defensible when documented.
A consult needs a documented request from another clinician, your opinion rendered, and a report back. A transfer of care is not a consult. And for Medicare and many plans, new patient plus G2211 often outpaces the consult family anyway; run both before assuming.
Since the 2020 descriptor revision, 29880 and 29881 include chondroplasty in the same or a separate compartment, and CMS NCCI states 29877 is not reported with knee arthroscopy codes 29866 to 29889. Medicare's G0289 applies only to loose or foreign body removal from a different compartment, not chondroplasty. Payer specific: a few commercial plans differ; check before appealing.
Routine care of the operative site is the package: that is 99024, no wRVU. A visit for a genuinely unrelated problem is payable with modifier 24, and a complication is payer specific. The note must make the distinction obvious.
99406 pays for 3 to 10 documented minutes and 99407 beyond that, on top of the E/M. The work is usually happening already; the minutes are what is missing.
