Primary Care Billing Services
Primary care is where the largest number of separately payable Medicare programs stack on top of ordinary office visits, and where the billing work is mostly documentation discipline rather than exotic coding. Five streams do the work: the office visit itself, leveled since 2021 on medical decision-making or on total time on the date of the encounter rather than on history and exam; the Medicare Annual Wellness Visit, with its own component list and its own once-in-12-months frequency rules; Chronic Care Management, which pays for documented clinical-staff time in a calendar month on patients with two or more chronic conditions; Transitional Care Management after a qualifying inpatient or observation discharge, on a contact clock and a face-to-face window; and the risk-adjustment documentation that decides what a Medicare Advantage panel is worth. MIPS sits over all of it as a payment adjustment rather than a billing code.
What leaks is rarely the code and usually the evidence behind it: a level chosen out of habit rather than read off the note, a wellness visit recalled a few weeks too early, a month of care coordination with no defensible time log, a discharge that never reached the follow-up queue, a chronic condition documented last year and not this one.
We handle the billing administration - coding, charge review, scrubbing, claim submission, denial work, posting and A/R - for practices from solo to multi-site groups. We do not furnish the clinical services themselves: CCM, TCM and remote physiologic monitoring are clinical programs your practice runs and your clinical staff staffs, and what we take on is the coding, the consent-and-time documentation trail those codes require, the claim and the follow-up. Onboarding splits the same way - the practice supplies payer contracts, fee schedules, EHR access and the clinical documentation, and we supply everything downstream of the note. This is the primary-care entry point on the site: family medicine and internal medicine each have their own page, and the difference that matters for billing is panel mix, not specialty designation.

What Is Primary Care Billing?
Primary care billing is the administration of the codes a practice is already earning: the office visit leveled on medical decision-making or on time, the Medicare Annual Wellness Visit, Chronic Care Management for documented clinical-staff time in a calendar month on a qualifying patient, Transitional Care Management after a qualifying discharge, and the diagnosis documentation that drives Medicare Advantage risk adjustment. When a Medicare patient has a significant, separately identifiable, medically necessary problem addressed at the same visit as the AWV, CMS says to report the additional office E/M code with modifier 25 - see CMS, Annual Wellness Visit, verified 17 September 2026. We run the coding, the documentation trail those codes require, the claim and the follow-up; the clinical programs themselves stay with your staff. The dollar figures in the code table below are CY2026 Medicare national unadjusted non-facility amounts - total non-facility RVUs times the 33.4009 nonqualifying-APM conversion factor in the CY2026 PFS relative value file. They are a national reference point before any geographic adjustment, and commercial contracts pay off their own fee schedules. If your panel skews one way or the other, the family practice and internal medicine pages cover those panel mixes directly.
- AWV: G0438 initial, G0439 subsequent - each billable once in a 12-month period, and not within 12 months of the IPPE (G0402)
- CCM 99490 pays once the 20-minute clinical-staff threshold is documented, and only one practitioner may bill it for a patient in a calendar month
- 2021 E/M rules: level on medical decision-making or on total time on the date of the encounter, not on history and exam
- Modifier 25 on the office E/M when a separately identifiable, medically necessary problem is addressed at the AWV
- Billing administration only - your clinical staff furnishes CCM, TCM and RPM; we code, document, submit and chase them

Common Billing Friction in Primary Care
E/M undercoding under the 2021 office-visit rules
The 2021 CMS and CPT overhaul replaced history/exam/MDM scoring for office visits with two equivalent paths: medical decision-making complexity (number and complexity of problems addressed, data reviewed, risk of complications) or total time on the date of the encounter. A visit that genuinely addresses several chronic conditions with medication management can support 99214 or 99215 where the documentation carries it. The gap between levels is real money: on the CY2026 Medicare non-facility national amounts, 99213 is about $95, 99214 about $136 and 99215 about $192, so a habitual 99213 default gives up roughly $41 to $97 on every visit that would have supported a higher level. We do not publish a practice-wide leakage estimate, because the size of the gap depends entirely on your panel and your documentation - it is a number we measure on your own claims history, not one we can assert in advance.
Annual Wellness Visit - G0438/G0439 and the same-day problem visit with modifier 25
The Medicare AWV is a health risk assessment, a personalized prevention plan, cognitive-impairment detection, depression and functional-ability review, and a written screening schedule. CMS's AWV component list does not include a routine physical examination, and the visit is not built to work up an acute or chronic complaint. When a Medicare patient comes in for an AWV and also has a significant, separately identifiable, medically necessary problem addressed, CMS's guidance is to report the additional office E/M code (99202-99205 or 99211-99215) with modifier 25 - that portion of the visit has to be medically necessary and reasonable to treat an illness or injury. Practices that bundle the problem visit into the AWV out of caution forfeit the E/M line, which on the CY2026 Medicare non-facility national amounts is roughly $95 for a 99213 or $136 for a 99214. Two frequency rules catch practices out: G0438 and G0439 are each billable only once in a 12-month period, and neither may be billed within 12 months of the initial preventive physical examination (G0402) for the same patient. Source: CMS, Annual Wellness Visit, verified 17 September 2026.
Chronic Care Management 99490/99439 - the 20-minute clinical-staff threshold
CCM (99490) covers the first 20 minutes of clinical-staff time per calendar month on care coordination for patients with two or more chronic conditions; +99439 covers each additional 20 minutes. On the CY2026 Medicare national amounts 99490 is about $66 non-facility and about $44 facility, and 99439 about $50 and $31. The requirements are documentary, not clinical-judgment calls: written or verbal patient consent obtained and recorded before billing, a comprehensive care plan, 24/7 access to a practitioner, use of a certified EHR, and a defensible record of the time. Two rules CMS states plainly and practices routinely miss - only one practitioner may provide and bill CCM for a patient in a calendar month, and non-complex CCM and complex CCM (99487/99489) cannot both be reported for the same patient in the same month. The CCM service itself is your clinical staff's work; what we run is the consent and time-tracking documentation trail, the monthly claim and the denial follow-up.

Transitional Care Management 99495/99496 - the 2-business-day contact and the 7-day and 14-day windows
TCM is one of the highest-value primary care codes and one of the easiest to lose on a technicality. CMS's requirements are specific on three points the page-one summaries usually blur. First, the qualifying discharge settings are an inpatient acute care hospital, inpatient psychiatric hospital, inpatient rehabilitation facility, long-term care hospital, skilled nursing facility, hospital outpatient observation or partial hospitalization, or partial hospitalization at a community mental health center - a discharge from the emergency department is not on that list. Second, interactive contact with the patient or caregiver by phone, email or in person must happen within 2 business days of discharge. Third, the two codes are not distinguished only by timing: 99495 requires at least moderate-complexity medical decision-making with a face-to-face visit within 14 calendar days of discharge, and 99496 requires high-complexity medical decision-making with a face-to-face visit within 7 calendar days. The face-to-face visit may be furnished via telehealth - CMS pays 99495 and 99496 as telehealth services. The 30-day period begins on the discharge day and only one TCM service may be reported per patient in it. On the CY2026 Medicare national non-facility amounts 99495 is about $220 and 99496 about $299. Source: CMS MLN908628, Transitional Care Management Services, verified 17 September 2026.
Risk-adjustment documentation on Medicare Advantage panels and the annual-recapture problem
CMS pays Medicare Advantage plans risk-adjusted capitation based on the diagnoses documented and submitted for each enrollee; how much of that reaches a primary care practice depends entirely on the practice's contract with the plan, which can be fee-for-service, a quality or coding incentive, or a shared-risk arrangement. The clinical documentation obligation is the same either way. For CY2026, CMS completed the phase-in of the 2024 CMS-HCC model and calculates risk scores using 100 percent of that model, whose clinical classification is version 28 - so condition-category numbers taken from the older 2020 (V24) model no longer identify the right categories, and any internal crosswalk built on them needs re-mapping. The recapture rule is unchanged and is where the revenue goes: a chronic condition must be documented and coded from a face-to-face encounter in each calendar year to count for that year's risk adjustment; it does not carry forward. Practices that document only the presenting complaint at each visit lose that capture at year-end reconciliation.

Primary Care-Specific Payer Issues We Watch For
Medicare
Issue: MIPS applies a positive, neutral or negative adjustment to Medicare payments based on the final score. Through the 2028 performance year the threshold is 75 points; a score of 18.75 or below draws the maximum negative adjustment of 9 percent, and the adjustment hits claims in the payment year beginning one year after the performance year ends
Our approach: We track MIPS quality measures through the year and support reporting across eligible clinicians so the score reflects the care actually delivered rather than what the coding happened to capture
UnitedHealthcare
Issue: Commercial plans differ on whether advance care planning (99497) is separately payable on the same date as a wellness visit, and several require the ACP time and content to be documented distinctly from the wellness visit. Medicare waives ACP cost sharing once a year when it is furnished on the same day by the same provider and billed with modifier 33 on the AWV claim
Our approach: We check the specific plan's policy before the encounter and make sure ACP documentation carries its own start and stop times and its own content, separate from the wellness visit
Aetna
Issue: Commercial preventive-care schedules do not always match USPSTF recommendations or Medicare's preventive benefit, and the covered ages and intervals for a given screening can differ by plan and by product within the same carrier. The annual preventive visit is also a different code family on a commercial plan than on Medicare - preventive medicine E/M, 99381-99387 for a new patient and 99391-99397 for an established one, leveled by patient age rather than by decision-making or total time, and not interchangeable with G0438/G0439 or with a problem E/M visit
Our approach: We verify the specific plan's preventive schedule for the patient's age and product before the screening is ordered, rather than assuming a single carrier-wide rule
BCBS
Issue: Blue Cross Blue Shield is a federation of independent licensees and Medicare Advantage products vary by plan, so risk-adjustment documentation expectations are set plan by plan rather than nationally - but the underlying CMS rule is constant: a chronic condition has to be documented and coded from a face-to-face encounter each calendar year to count for that year
Our approach: We review chronic-condition documentation annually against the current CMS-HCC model and flag conditions that were coded last year but not this one, so the gap is closed at a visit rather than discovered at reconciliation
What We Handle
E/M coding under the 2021 MDM and time-based rules
Provider-by-provider E/M review against the MDM elements (problems addressed, data reviewed, risk) and the time-based alternative, with documentation templates that defend 99214 and 99215 on the complex chronic-disease panels where the record supports them. We do not select a level the note does not carry.
Annual Wellness Visits - G0438, G0439, and the same-day E/M
AWV claim preparation with the health risk assessment, prevention plan and cognitive-impairment elements evidenced in the record; modifier 25 on the same-day office E/M when a significant, separately identifiable and medically necessary problem was addressed; and eligibility checking against the once-per-12-months limit and the 12-month bar after an IPPE, so recalls do not generate denials.
Chronic Care Management billing - 99490, 99439, 99487, 99489
Billing administration for a CCM program your practice runs: consent capture and retention, care-plan and time-log evidence assembled for the claim, the monthly billing cycle, and the concurrent-billing checks (one practitioner per patient per month; no non-complex and complex CCM in the same month). The clinical staff time and the care plan itself are yours - we bill and defend them, we do not furnish them.
Transitional Care Management billing - 99495, 99496
Discharge-feed reconciliation so post-discharge follow-ups are flagged against the 2-business-day contact requirement and the 7-day or 14-day face-to-face window, with the decision-making level on the note matched to the code - moderate for 99495, high for 99496 - and the qualifying-setting check that keeps emergency-department discharges out of the TCM queue.
Remote Physiologic Monitoring billing - 99453, 99454, 99457, 99458
Claim-side support for an RPM program your practice operates and staffs: device-setup billing (99453), the monthly device-supply code (99454, which requires a documented 16 days of transmissions in a 30-day period), and clinical-staff treatment-management time (99457 first 20 minutes, +99458 each additional 20 minutes). We do not select, supply or manage devices and we do not provide the monitoring service.
MIPS reporting support and risk-adjustment documentation review
Quality-measure tracking, Promoting Interoperability and Improvement Activities documentation, and submission through the reporting mechanism you are eligible for. Under traditional MIPS the performance threshold is 75 points through the 2028 performance year, the maximum negative adjustment is 9 percent, positive adjustments are scaled for budget neutrality, and the adjustment lands on claims in the payment year beginning one year after the performance year ends. Plus annual review of chronic-condition documentation on Medicare Advantage panels against the current CMS-HCC model.

Key Primary Care CPT Codes
| CPT Code | Description | Medicare Amount CY2026 national, non-facility |
|---|---|---|
| 99214 | Office visit, established patient, moderate complexity | $136 |
| 99215 | Office visit, established patient, high complexity | $192 |
| G0439 | Annual wellness visit with personalized prevention plan, subsequent | $138 |
| G0438 | Annual wellness visit with personalized prevention plan, initial | $174 |
| 99490 | Chronic care management, clinical staff, first 20 minutes per month | $66 |
| 99457 | Remote physiologic monitoring treatment management, first 20 minutes | $52 |
| 96127 | Brief emotional/behavioral assessment | $5 |
| 99497 | Advance care planning, first 30 minutes | $87 |
Amounts are the Medicare national unadjusted non-facility amounts for CY2026, computed from the published CMS relative value file. They are not what a commercial payer pays, and your locality adjustment moves them. A dash means Medicare publishes no amount for that code — because it is non-covered, bundled, or priced outside the fee schedule.
Why General Billing Teams Miss Primary Care Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for primary care coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in primary care.
Under-coding high-complexity visits
Primary Care encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for primary care procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn primary care denials quickly.
“Primary care has more separately payable programs stacked on it than any other specialty. Between CCM, RPM, AWV, advance care planning and TCM, there is a whole layer of work most practices are already doing and never billing - and the thing that stops them billing it is almost always a documentation trail nobody set up, not a coding decision.”

Primary Care Billing Terms
- Annual Wellness Visit (AWV)
- A Medicare preventive service built around a health risk assessment, a personalized prevention plan, cognitive-impairment detection, depression and functional-ability review and a written screening schedule. Billed as G0438 (initial) or G0439 (subsequent), each once in a 12-month period. CMS's component list does not include a routine physical examination.
- MIPS (Merit-based Incentive Payment System)
- The CMS program that adjusts Medicare payments based on performance in quality, promoting interoperability, improvement activities and cost. Through the 2028 performance year the threshold is 75 points; the maximum negative adjustment is 9 percent and positive adjustments are scaled for budget neutrality.
- Risk-Adjustment (CMS-HCC) Documentation
- The diagnosis documentation that drives CMS's risk-adjusted payment to Medicare Advantage plans. For CY2026 CMS uses 100 percent of the 2024 CMS-HCC model (clinical classification version 28). Chronic conditions must be documented and coded from a face-to-face encounter each calendar year; they do not carry forward.
- Transition Care Management (TCM)
- Post-discharge care coordination after a qualifying inpatient, observation or partial-hospitalization discharge. Requires interactive contact within 2 business days. 99495 needs at least moderate-complexity decision-making and a face-to-face visit within 14 calendar days; 99496 needs high-complexity decision-making and a face-to-face visit within 7 calendar days. Only one TCM service per patient in the 30-day period.
- Advance Care Planning (ACP)
- Billable counseling (99497/99498) on advance directives, living wills and healthcare proxy designations. It can be furnished during an AWV at the patient's discretion - Medicare waives the deductible and coinsurance once a year when it is billed with modifier 33 on the same AWV claim by the same provider - or as a standalone service with its own time documentation.
- Remote Physiologic Monitoring (RPM)
- Technology-enabled monitoring of physiologic data (blood pressure, glucose, weight) with clinical review. Billed with 99453 for device setup, 99454 for the monthly device supply (which requires documented transmissions on at least 16 days in a 30-day period), and 99457/+99458 for treatment-management time. The monitoring is a clinical service the practice furnishes, not a billing function.

Common Questions
Common questions about primary care billing services.
Request a Specialty Billing Review
See how specialty-specific billing support can improve reimbursement visibility for primary care billing services.
Request ReviewWhat does chronic care management actually pay, and what has to be in the record?
On the CY2026 Medicare national non-facility amounts, 99490 (first 20 minutes of clinical-staff time in a calendar month) is about $66 and each additional 20 minutes on +99439 is about $50; the facility-setting amounts are lower. We will not quote you an annual program total, because it depends on how many of your patients are eligible, consent, and actually receive 20 documented minutes in a given month - that is measurable on your own data and not before. What the claim needs is fixed: consent recorded before billing, a comprehensive care plan, 24/7 access to a practitioner, a certified EHR, a defensible time log, and confirmation that no other practitioner billed CCM for that patient that month. Requirements and codes are in CMS MLN909188, Chronic Care Management Services, verified 17 September 2026.
How do you help with MIPS reporting?
We track eligible quality measures through the reporting year, code so the measures are captured, monitor performance against benchmarks and submit through the mechanism you qualify for, focusing on measures where your practice can score well. For context on the stakes: under traditional MIPS the performance threshold is 75 points through the 2028 performance year, a final score of 18.75 points or below draws the maximum negative adjustment of 9 percent, scores between that and the threshold draw a sliding negative adjustment, positive adjustments above the threshold are scaled to keep the program budget neutral, and the adjustment applies to claims in the payment year that begins one year after the performance year ends. CMS publishes the current thresholds and adjustment table on the Quality Payment Program site at qpp.cms.gov; figures verified 17 September 2026.
Can you run our remote patient monitoring program?
No - we bill it, we do not run it. RPM (99453-99458) is a clinical service: your practice selects and supplies the devices, your clinical staff reviews the data and provides the treatment-management time, and a practitioner in your practice is responsible for the care. What we do is the billing administration on top of that: the device-setup code, the monthly supply code (99454 requires documented transmissions on at least 16 days in a 30-day period), the treatment-management time codes, the concurrent-billing checks against CCM and TCM, and the denial work. The same split applies to chronic care management and transitional care management. If a billing company offers to supply the clinical side of these programs, that is a different kind of arrangement with its own compliance questions, and it is not what we do.
Are G0438 and G0439 CCM codes?
No. G0438 (initial) and G0439 (subsequent) are Medicare Annual Wellness Visit codes; Chronic Care Management uses CPT 99490 with add-on 99439, or 99487/99489 for complex CCM. Both can apply to the same patient in the same year, and an AWV can share a date with a significant, separately identifiable, medically necessary office E/M reported with modifier 25. Each AWV code is billable only once in a 12-month period, and neither may be billed within 12 months of the initial preventive physical examination (G0402). See CMS, Annual Wellness Visit, verified 17 September 2026.
