99214
Office o/p est mod 30 min
Office or other outpatient visit, established patient, moderate-level medical decision making OR 30-39 minutes of total time on the date of the encounter. The CMS 2026 wRVU for 99214 is 1.92, the workhorse value in primary care. Medicare allowable is calculated using the national GPCI and the 2026 conversion factor of $33.4009.
The 2021 E/M guidelines let you bill 99214 by time or MDM. Here is the decision tree, with documentation templates for each method.
Modifier 25 carves an E/M out of a same-day procedure or preventive service. Here is when to use it, when to skip it, and the documentation that survives audit.
When to use it
99214 is the workhorse of primary care and most outpatient subspecialties. Use it when at least one of these is true: two or more chronic problems with progression, treatment changes, or side effects; one undiagnosed new problem with uncertain prognosis; one acute illness with systemic symptoms; or prescription drug management at any complexity.
Full guidance
Prescription drug management on its own satisfies the moderate-risk element, which is why straightforward chronic disease follow-ups with a med adjustment routinely clear the 99214 bar. Time-based alternative is 30 to 39 minutes of total time on the date of the encounter. Pick the method that supports the strongest note: encounters with prescription changes are usually cleaner under MDM; encounters with extensive counseling or care coordination are usually cleaner under time.
Documentation checklist
- ✓MDM track: meet moderate complexity on two of three elements. Problems Addressed: two or more stable chronic, OR one chronic with progression, OR one undiagnosed new with uncertain prognosis. Data Reviewed: moderate (at least one of: review of external notes plus ordering tests; independent interpretation of imaging; or discussion with another provider). Risk: moderate (prescription drug management, decisions about surgery without identified risk, IV fluids without additives, social determinants).
- ✓Time track: document total physician or QHP time on the date of the encounter, between 30 and 39 minutes. Include all qualifying activities (chart review, history, exam, ordering, counseling, documentation, care coordination on date of encounter).
- ✓Prescription drug management satisfies moderate risk by itself. Document the prescription and the indication explicitly.
- ✓Independent interpretation counts only when you read the study yourself, not when you read a radiologist's report.
- ✓External data counts only when you reviewed records from a different practice or specialty. Your own labs and imaging count toward ordering, not reviewing.
- ✓Modifier 25 is required when a same-day minor procedure or screening service is billed. Document the separately identifiable E/M work.
Common pitfalls
- !Calling a 99214 moderate complexity without prescription drug management, a problem with uncertain prognosis, or a moderate-data element. The most common CMS audit finding in outpatient billing.
- !Counting your own labs and imaging as external data. Those count toward the ordering category, not the reviewing category.
- !Not documenting independent interpretation when reviewing outside images. A one-line summary of your reading satisfies the data element.
- !Time-based 99214 with vague time documentation. Audit-proof language: "I spent 35 minutes of total time on the date of the encounter on care of this patient, including chart review, history-taking, exam, counseling, documentation, and ordering of follow-up labs."
- !Missing the G2211 add-on. Most 99214s in primary care are eligible. Estimated 38 percent eligibility, observed capture under 5 percent.
- !Bundling a same-day vaccine administration without the appropriate vaccine admin code and modifier 25 on the 99214.
Payer notes
Medicare audits the 99213-to-99214 ratio at the clinician and practice level. Commercial payers vary: UnitedHealthcare and Anthem occasionally apply post-payment reviews on 99214 when prescription management is not clearly documented. Medicare Advantage plans typically follow Medicare guidelines. For telehealth, use POS 10 (home) or POS 02 (other) with modifier 95; some commercial payers require POS 11 with modifier 95.
