SHORT DEFINITION

CPT 99212 is the entry-level Evaluation and Management (E/M) code for established patient office or outpatient visits requiring straightforward medical decision-making and/or at least 10 minutes of total provider time on the date of encounter.

LONG DEFINITION

CPT 99212 describes an office or other outpatient visit for the evaluation and management of an established patient that involves:

Medically appropriate history and/or examination based on the patient’s presenting problem
Straightforward medical decision-making (low risk, limited number of problems, minimal data review)
Total provider time of 10-19 minutes (face-to-face and non-face-to-face combined)
Minimal complexity in clinical assessment and management planning

This code is used for minor or self-limited problems such as:

Common cold, viral syndrome, or mild upper respiratory infection
Simple rash or skin irritation
Medication refill with no adjustments
Routine follow-up for chronic stable condition
Blood pressure check and medication review
Medication side effect management
Diagnostic test result review with reassurance needed

Key distinction: Unlike CPT 99211 (staff-level visit), 99212 requires direct provider evaluation and management. The provider must personally see the patient and deliver the medical service.

WORK RELATIVE VALUE UNITS (wRVUs) & COMPONENTS

Work RVU Breakdown (2025)

RVU Component	Value	What It Represents
Work RVU	0.70	Physician work and cognitive effort
Practice Expense RVU (non-facility)	0.56	Rent, supplies, equipment, staff time
Practice Expense RVU (facility)	0.34	Lower due to hospital/facility coverage
Malpractice RVU	0.04	Malpractice insurance costs
TOTAL RVU (non-facility)	1.30	Total relative value units
TOTAL RVU (facility)	1.08	Total relative value units (lower)

RVU Conversion to Dollar Amount (2025)

Formula: RVU × Conversion Factor (CF) × Geographic Practice Cost Index (GPCI) = Payment

2025 Medicare Conversion Factor: $32.3465

Typical Calculations (Non-Facility, Mid-Range GPCI = 1.0):

0.70 wRVU × $32.3465 = * *$ 22.64** (work component)
0.56 PE RVU × $32.3465 = * *$ 18.11** (practice expense)
0.04 MP RVU × $32.3465 = * *$ 1.29** (malpractice)
Total = ~$42.04 per visit (non-facility, GPCI 1.0)

Real-World Range (2025):

Non-Facility: $38 -$ 48 (depending on GPCI, which ranges from 0.88 to 1.46)
Facility-Based: $30 -$ 38 (lower PE RVUs)

GLOBAL PERIOD

Global Period Status: 000 (Zero-Day Global)

What This Means:

CPT 99212 is an office visit code with NO global period
There are no pre-operative or post-operative days bundled with this code
The code includes only the services on the date of service
No global period modifiers (24, 25, 57) are typically needed
Can be billed on the same day as a procedure with modifier -25 if separately identifiable from a procedure with global period

Note

Exception: If billed during a surgical global period (e.g., within 90 days post-op) for unrelated evaluation/management, use modifier -24 to indicate it’s unrelated to the global surgical package.

ESTABLISHED PATIENT DEFINITION (Medicare)

For CPT 99212 to be appropriate, the patient must be “established”:

An established patient is one who has received professional services (evaluation and/or management of a health problem) from the same provider or another provider of the same specialty/subspecialty within the same group practice within the past 3 years.

Key Points:

Timing: Within 3 calendar years from date of current visit
Same provider OR same specialty within same group = established
If patient hasn’t been seen in 3+ years, they are NEW, not established
Different specialty group or facility = may be NEW (payer-dependent)

DOCUMENTATION REQUIREMENTS FOR 99212

Minimum Documentation Components

Medical Decision-Making (MDM) - Straightforward:

Number of diagnoses/problems: Minimal (1-2)
Amount/complexity of data: Minimal (0-1 items)
Risk of complications/death: Minimal (low-risk presenting problem)

History & Physical Exam:

History: Focused or detailed (limited to presenting problem)
Exam: Focused or expanded problem-focused (1-3 systems)
Chief Complaint: Documented
Pertinent history: HPI, relevant ROS, relevant PMH

Assessment & Plan:

Diagnosis identified
Management plan documented (continue, prescribe, refer, monitor)
Patient education or reassurance documented
Follow-up plan (return PRN, schedule revisit, etc.)

Time Documentation (if using time):

Total time ≥10 minutes on date of service
May include: chart review, history, exam, decision-making, counseling, coordination, documentation
Does NOT include time spent on separate billable procedures

BILLING RULES & FREQUENCY

Billing Restrictions

Maximum frequency: No Medicare limit per se, but must be medically necessary
- Medicare expects patients with chronic conditions to be seen at intervals appropriate to their condition
- Frequent visits to the same provider for the same condition may trigger audits
Medically necessary: Visit must be justified by the patient’s presenting problem or chronic condition management
No bundling with preventive visits: If 99212 billed same day as preventive visit (e.g., CPT 99381-99395, 99401-99429), use modifier -25 on the 99212

Staff-Level (Non-Provider) Alternative

CPT 99211 can be billed for established patient visits performed by staff (nurse, MA, medical assistant) under supervision of a provider
- Lower RVU, lower reimbursement
- Does NOT require provider presence or direct evaluation
- Must have provider supervision

CODING GUIDELINES & RULES (2021 AMA E/M GUIDELINES)

Decision Framework for E/M Code Selection

Step 1: Determine if New or Established Patient

Established (within 3 years) → Use codes 99212-99215
New → Use codes 99201-99205

Step 2: Choose Coding Method

Time-Based: ≥10 minutes for 99212
MDM-Based: Straightforward complexity for 99212

Step 3: Apply to 99212

Time requirement: ≥10 minutes (10-19 min typical for 99212; 20+ would be 99213)
MDM requirement: Straightforward (low risk, limited problems, minimal data)

Step 4: Bill Accordingly

If time OR MDM supports 99212 → Bill 99212
If complexity is moderate or higher → Bill 99213, 99214, or 99215

Time-Based Coding

For 99212, total time must be ≥10 minutes:

Code	Time	MDM	Typical Use
99211	<10 min OR no provider	Any	Deleted; Staff-level visit
99212	10-19 min	Straightforward	Low-complexity provider visit
99213	20-29 min	Low-Moderate	Moderate complexity
99214	30-39 min	Moderate-High	Significant workup
99215	≥40 min	High	Complex, high-risk

Time Includes:

Face-to-face provider time with patient
Non-face-to-face time spent on the same date of service:
- Chart review and medical record documentation
- Ordering tests or procedures
- Referring to other providers
- Prescription writing
- Communicating with patient or family
- Counseling and patient education
- Care coordination with other providers

Time Does NOT Include:

Time spent on a separately billable procedure (e.g., injection, biopsy)
Time on previous or future dates of service

COMMON MODIFIERS USED WITH 99212

Frequently Used Modifiers

Modifier	Description	When to Use	Example
-25	Significant, separately identifiable E/M service by same physician on same day as procedure	When billing 99212 with a procedure (e.g., vaccines, injections, wound care) that has global period or separate RVU	99212-25 + 90834 (vaccine admin)
-24	Unrelated evaluation and management service by same physician during postoperative period	When billing 99212 during post-op global period (10-day or 90-day) for unrelated problem	Patient s/p knee surgery (90-day global), now presents for unrelated HTN check → 99212-24
-59	Distinct procedural service	When bundling issues exist and -25 doesn’t clearly convey distinctness	Rarely used with E/M; usually for procedures
-76	Repeat procedure by same physician	When repeating same E/M (rare, usually not needed for E/M)	Rarely applicable to 99212
-91	Repeat clinical diagnostic laboratory test	Not applicable to E/M codes	N/A
None (most common)	Standard billing	When no concurrent procedure or post-op status	99212 (routine visit)

Modifier -25 Usage (Most Common)

When to use -25 with 99212:

Vaccine administration (CPT 90658, etc.) - Vaccine admin is separately billable
Injection/intramuscular medication - Separate RVU from 99212
Wound care/dressing - Separate from the E/M visit
Lab specimen collection - If not routine (e.g., venipuncture may be included)

Example Documentation:

Patient presents for annual flu vaccine
Vital signs taken, vaccine administration performed
Brief discussion about seasonal illness prevention
Total time: 12 minutes
Coding: 99212-25 + 90658

MEDICARE RULES FOR 99212

CMS-Specific Rules & Policies

1. No Prior Authorization Required

99212 does not require pre-auth for most Medicare Advantage plans
Check payer-specific rules (some MA plans may require auth)

2. Time Documentation

If billing based on time, total time must be documented in medical record
Time must be documented on date of service
For established patients, 10 minutes meets minimum for 99212

3. Billing During Preventive Visit

Can bill 99212 same day as preventive visit (CPT 99381-99395, 99401-99429) with modifier -25
Preventive visit and problem-focused visit must be distinct and separately identifiable
Both services must have separate medical necessity

4. Billing During Global Period

Can bill 99212 during post-op global period with modifier -24 if the visit is for an unrelated problem
Example: Patient post-op Day 15 from appendectomy (90-day global) presents for unrelated hypertension check → 99212-24
If visit is related to post-op care, it may be included in global period (no separate charge)

5. Telehealth Parity

99212 can be billed for telehealth/virtual visits at the same reimbursement rate as in-person visits
Technology-based care services (98970-98972) are separate codes with different valuation

6. RHC/FQHC Billing

99212 is reportable in RHC (Rural Health Clinic) and FQHC (Federally Qualified Health Center) settings
RHCs/FQHCs receive payment from All-Inclusive Rate (AIR) or Prospective Payment System (PPS), not individual fee-for-service
Individual provider cannot bill 99212 if employed by RHC/FQHC (payment goes to facility)

7. Office vs. Facility Setting

Non-facility (private office/clinic): Higher PE RVU (0.56) → Higher reimbursement
Facility-based (hospital outpatient, ASC, RHC, FQHC): Lower PE RVU (0.34) → Lower reimbursement
CMS pays less for facility-based care due to facility overhead

LOCAL COVERAGE DETERMINATIONS (LCDs) & NATIONAL COVERAGE DETERMINATIONS (NCDs)

National Coverage Determination (NCD)

There is NO specific NCD for CPT 99212. However, Medicare has general coverage policies:

Covered:

Office/outpatient E/M services are covered when medically necessary and furnished by a qualified provider
99212 covered for established patients with straightforward problems
No frequency limitation per Medicare statute (must be medically necessary)

Not Covered:

Duplicate E/M services same day by same/different provider (must be for different problem with -25)
Services deemed not medically necessary (routine social visits)
Services outside scope of provider license/credential

Local Coverage Determinations (LCDs) - Payer-Specific

LCDs vary by Medicare Administrative Contractor (MAC) jurisdiction. Common LCD restrictions include:

Restriction Type	Example
Visit Frequency	Not more than once per week for chronic disease management (varies by condition)
Time Documentation	Must be documented in medical record if using time-based coding
Medically Necessary	Visit must be tied to a valid ICD-10 diagnosis
Established Status	Must confirm patient is established per payer definition
Concurrent Services	Cannot bill 99212 with 99211 same day
Procedure Bundling	Some procedures bundle E/M (check procedure LCD)
Provider Credentials	Provider must be enrolled and in-network (if applicable)

To find LCD for your jurisdiction:

Go to CMS’s Local Coverage Determination (LCD) Search Tool: https://www.cms.gov/cclc/lcd
Enter your MAC jurisdiction
Search for “office visit” or “evaluation and management”
Review any specific restrictions on 99212

COMMON MODIFIERS & GLOBAL PERIOD RULES

Modifier -24 (Post-Operative E/M)

Use when: Billing 99212 during a post-operative global period for an unrelated problem

Scenario:

Patient had appendectomy (44950) on 1/1/2026 (90-day global = through 3/31/2026)
On 1/20/2026, patient comes in for unrelated hypertension check
Codes: 99212-24 (unrelated E/M during global period)

Not used for: Related post-op care (e.g., follow-up for surgical wound check)

Modifier -25 (Distinct Procedural Service)

Use when: Billing 99212 same day as a procedure with separate RVU

Common Examples:

Vaccine administration (90658 + 99212-25)
Intramuscular injection (96372 + 99212-25)
Wound care/dressing change (12001-12007, etc. + 99212-25)
Nebulizer treatment (94060 + 99212-25)

Documentation requirement: E/M must be distinct and separately identifiable from procedure

DOCUMENTATION TIPS FOR 99212

What to Document

✓ SHOULD INCLUDE:

Chief Complaint - Patient’s stated reason for visit
History of Present Illness (HPI) - Focused to the presenting complaint (can be brief for 99212)
Relevant Past Medical History - Any conditions relevant to current problem
Current Medications - Especially if E/M includes medication review
Vital Signs - At minimum BP, HR; may include temp if relevant
Focused Physical Exam - Systems relevant to complaint
Assessment/Diagnosis - ICD-10 code and brief impression
Medical Decision-Making - Treatment plan, orders, education, disposition
Time - If using time-based coding, document total time spent
Legible Provider Signature/Authentication - Provider name, credential, date/time

✗ SHOULD AVOID:

Over-documentation (verbose notes for straightforward visit)
Excessive system review (ROS of all 14 systems not needed for simple problem)
Exam findings unrelated to complaint (if patient has chest pain, don’t document skin findings unless relevant)
Copy-paste from previous notes without updating for current visit
Blank or generic statements (“patient well, no complaints”)

Time Documentation Format (If Using Time)

Recommended format in note:

“Total time spent on this encounter: 15 minutes, which includes: review of chart (2 min), history and focused physical examination (5 min), assessment and medical decision-making (4 min), patient education regarding viral illness and supportive care (3 min), documentation (1 min).”

Or simply:

“Time spent: 15 minutes”

AUDIT DEFENSE CHECKLIST FOR 99212

Before billing 99212, verify:

RED FLAGS FOR AUDITORS

99212 claims are at audit risk if:

❌ Documentation is minimal or missing (no exam, brief 1-line assessment)
❌ Time is not documented when using time-based coding
❌ Patient is clearly NEW, not established (no prior service within 3 years)
❌ Problem is complex (multiple comorbidities, complicated decision) but coded as straightforward
❌ Copay or payment patterns suggest routine billing regardless of complexity
❌ Same diagnosis coded repeatedly with identical notes (suggests copy-paste)
❌ Physical exam findings do not match chief complaint
❌ Risk profile does not match straightforward complexity (e.g., hypotensive patient, altered mental status = not straightforward)
❌ Procedure bundled with 99212 without -25 modifier
❌ Multiple E/M codes billed same day without separate modifiers/diagnoses

MEDICARE RULES & RESTRICTIONS

Who Can Bill 99212?

Qualified Providers:

MD (Medical Doctor)
DO (Doctor of Osteopathic Medicine)
NP (Nurse Practitioner) - with state license/Medicare billing number
PA (Physician Assistant) - with state credential/Medicare billing number
CNM (Certified Nurse Midwife) - for obstetric E/M
CRNA (Certified Registered Nurse Anesthetist) - limited circumstances
PT (Physical Therapist) - for PT-specific E/M (CPT 97161-97163, not 99212)
OT (Occupational Therapist) - for OT-specific E/M (CPT 97167-97169, not 99212)

Note: Some states allow other providers (RN, LPN, etc.) to bill under supervision; check state law and payer policy.

RHC/FQHC Restrictions

If provider is employed by RHC or FQHC:

99212 is still reportable but payment goes to facility’s All-Inclusive Rate (AIR) or Prospective Payment System (PPS)
Individual provider cannot bill separately for 99212
Facility receives bundled payment for all services furnished to that patient on that day
Exception: 2025 rule finalized allowing separate payment for CPT 99212-99215 at national PFS rates when reported alone or with other payable services (check facility’s current payer rules)

Telehealth Coverage

CPT 99212 via Telehealth:

Covered at same rate as in-person visit (no payment reduction)
No geographic restrictions (can see patients in any state with proper licensing)
Requires proper informed consent and technology capable of full encounter
Some payers may have different rules; verify with each payer

Related codes (instead of standard 99212):

CPT 98970-98972 - Remote Therapeutic Monitoring (not the same as telehealth E/M)
CPT 99441-99443 - Established patient office/outpatient visit, non-face-to-face (audio-only) - lower RVU

Concurrent Billing Issues

Cannot bill 99212 AND 99211 same day (for same patient):

Choose one based on complexity/time
If multiple encounters (e.g., follow-up visit same day), document that they are separate encounters

Can bill 99212 AND procedure same day with modifier -25:

Must be separately identifiable (distinct E/M service, not routine to procedure)
Common: 99212-25 + vaccine, injection, wound care, etc.

COMPLIANCE & CODING EXAMPLES

Appropriate 99212 Use Cases ✓

Acute viral URI - Established patient, cold symptoms, reassurance and supportive care
Stable chronic disease check-in - HTN well-controlled, BP check, refill medications
Simple medication side effect - Mild headache from new BP med, adjust if needed
Routine follow-up visit - Established patient, previously treated problem, no new issues
Vaccine administration with brief E/M - Flu shot + vital signs + education (with -25)
Skin tag/mole check - Benign-appearing lesion, reassurance, no intervention needed
Medication refill visit - Patient requesting refill, brief check-in, no medication changes
Lab result follow-up - Established patient, minor abnormality, straightforward plan

Inappropriate 99212 Use (Upcoding Risks) ✗

❌ Complex HTN with multiple medications - Patient has resistant HTN, recent changes, needs to assess response → Use 99213 or higher
❌ New diagnosis requiring workup - Patient presents with chest pain, needs EKG, cardiology referral, multiple tests → Use 99213 or higher
❌ Multiple chronic conditions with exacerbation - Diabetic patient with nausea, may be DKA, needs labs and IV fluids → Use 99213 or higher
❌ Complex medication reconciliation - Patient on 8 medications, multiple interaction concerns, needs adjustment → Use 99213 or higher
❌ Preventive visit billed as 99212 - Annual exam should use CPT 99381-99395 (preventive) or 99401-99429 (health risk appraisal), not 99212 (problem-focused)
❌ High-risk problem - Syncope, chest pain, severe headache → Use 99213 or higher

FREQUENTLY ASKED QUESTIONS (FAQs)

Q: Can I bill 99212 if visit is <10 minutes but I determined the complexity?
A: No. For established patients, 10 minutes is the minimum threshold for 99212. If <10 min, must bill 99211.

Q: Can staff (MA/LPN) perform the visit and I bill 99212?
A: No. 99212 requires direct provider evaluation and management. If staff-only visit under supervision, bill 99211.

Q: How do I document time if the visit was quick?
A: Simply state in the note: “Total time: 12 minutes” or break it down: “Chart review 2 min, H&P 5 min, assessment/plan 5 min.”

Q: Can I bill 99212 if patient calls with a question?
A: Only if the encounter is face-to-face (in-person or telehealth with audio/video). Telephone-only calls are CPT 99441-99443 (lower RVU).

Q: What if a preventive visit becomes problem-focused?
A: Bill the preventive code (99381-99395) as primary, and add 99212-25 if a significant, separately identifiable problem is addressed.

Q: Is 99212 appropriate for post-op follow-up?
A: Only if the visit is for an unrelated problem (use -24 modifier). If it’s post-op wound check/related follow-up, it’s typically included in the global period at no extra charge.

Q: Can I bill 99212 if I referred the patient to another provider same day?
A: Yes, referral is part of the E/M plan. But if the referral was the only service (no evaluation), it may not be separately billable.

Q: Is there a frequency limit for 99212 per patient per year?
A: No Medicare frequency limit, but visits must be medically necessary. Payers may have limits; check with each payer.

Q: What’s the difference between 99212 and CPT 98970 (Remote Therapeutic Monitoring)?
A: 99212 is a live office/outpatient visit. CPT 98970-98972 are for asynchronous monitoring (e.g., patient uploading BP readings; provider reviews later). Different RVUs and uses.

REAL-WORLD BILLING TIPS

Tips to Maximize Compliance & Revenue

Use time when possible - If visit is 10-19 minutes, documenting time supports straightforward coding
Link diagnosis to chief complaint - ICD-10 diagnosis should match the reason for visit
Keep notes organized - Separate HPI, PMH, meds, exam, assessment, plan for clarity
Document barriers to compliance - If visit is quick but patient education/counseling was extensive, note that
Use -25 modifier correctly - When vaccines or injections billed same day, always use -25
Verify patient established status - Check EHR to confirm prior visit within 3 years
Review payer-specific rules - Some Medicare Advantage plans may have restrictions on 99212 frequency
Don’t upcode for speed - Efficiency is good, but complexity must match coding level
Avoid copy-paste - Update notes each visit; different patients have different presentations
Train staff on established patient definition - Ensure rooming staff correctly flag new vs. established
