Where We Fit In
The Difference a Specialty-Trained Billing Team Makes
Most internal medicine practices do not lose revenue because claims go unsubmitted. They lose it because a 99214 gets billed as a 99213, a chronic care management month goes untracked, or an Annual Wellness Visit is billed under the wrong G-code and denies outright. Thrive’s internal medicine medical billing team codes, submits, and follows up on every encounter your practice generates, with the specific rules of E/M leveling, chronic care timing, and Medicare wellness sequencing built into how we work.
We are not a billing platform you log into and manage yourself. Your account is handled by a team that reviews documentation, catches undercoding before submission, and stays on aged claims until they resolve.

Scope of Work
Behind the Scenes of Your Internal Medicine Billing
Every task in the billing cycle, handled with the specific coding and timing rules internal medicine requires — not a generic checklist applied across specialties.
Eligibility & Benefits Verification
Prior Authorization
Imaging, specialist referrals, and diagnostic testing cleared ahead of the visit, including the extra layers Medicare Advantage plans add on top of standard Medicare rules.
Coding & Claim Scrubbing
E/M level selection by medical decision-making or time, CCM/TCM code assignment, and modifier review completed before a claim ever leaves the building.
Claims Submission
Complete claims submitted to Medicare, Medicare Advantage, Medicaid, and commercial payers on a same-day cadence.
Denial Management & Appeals
Root-cause review on every denial — from downcoded E/M visits to AWV frequency edits — with appeals filed inside payer deadlines.
AR Follow-Up
Aged claims worked on a set schedule instead of sitting in a queue until timely-filing limits pass.
Patient Billing & Collections
Clear statements and respectful follow-up handled without creating front-desk complaints.
Payment Posting & Reconciliation
Every remit matched against the expected allowable so underpayments get flagged instead of quietly absorbed.
Credentialing & Payer Enrollment
Reporting
Revenue reporting and review
Clean claim rate, AR aging, denial rate, and CCM/AWV capture tracked and shared monthly.
Internists' RCM Doesn't Look Like Everyone Else's
Procedure-heavy specialties bill for what was done. Internal medicine bills for how much complexity was managed and how carefully that complexity was documented — which means two internists seeing the same volume of patients can post very different revenue depending on coding discipline alone. That’s why we staff internal medicine accounts with coders trained specifically in E/M leveling and chronic care timing, not a rotating pool assigned across every specialty we serve.
Coding Reference
Internal Medicine CPT Codes We Bill Most
The evaluation and management, wellness, and chronic care codes that make up the majority of internal medicine claim volume.
- 99202–99205
New patient office visit
Initial E/M encounter, level set by medical decision-making or total time on the date of service.
- 99211–99215
Established patient office visit
Follow-up and chronic-condition management visits for patients seen within the prior three years.
- G0402
Initial preventive exam
One-time "Welcome to Medicare" visit, available in the first 12 months of Part B enrollment.
- G0438
Initial Annual Wellness Visit
First-ever Medicare AWV; billable once per beneficiary, ever, at any practice.
- G0439
Subsequent Annual Wellness Visit
Annual AWV following the initial visit, billable every 12 months after.
- 99490 / 99439
Chronic care management
Staff-directed monthly care coordination for patients with two or more chronic conditions.
- 99487 / 99489
Complex chronic care management
Higher-complexity CCM requiring moderate-to-high medical decision-making.
- 99424–99427
Principal care management
Monthly care management for a single high-risk chronic condition.
- 99495 / 99496
Transitional care management
Post-discharge coordination requiring a face-to-face visit within 14 or 7 days.
- 99497 / 99498
Advance care planning
Counseling on advance directives, billed with or without the same-day AWV.
- 93000
Electrocardiogram
In-office EKG with tracing, physician interpretation, and report.
- 36415
Venipuncture
Routine diagnostic blood draw.
- G2211
Visit complexity add-on
Recognizes ongoing, longitudinal management alongside a base E/M code; not billable on its own.
What's the difference between MDM-based and time-based E/M coding?
Medical decision-making measures the number and complexity of problems addressed, data reviewed, and risk of complications. Time-based coding instead counts total minutes spent on the date of service, including chart review and orders. A claim can only be built one way — mixing the two is a common cause of downcoding.
What is CPT add-on code G2211?
G2211 recognizes the added complexity of serving as a patient's ongoing point of contact for a chronic or serious condition. It's billed alongside an office visit E/M code, and under the 2026 Medicare fee schedule it adds a modest per-visit amount that many internal medicine practices leave unbilled simply through inconsistency.
Where Revenue Leaks
Eight Ways Internal Medicine Claims Lose Revenue
Every one of these is specific to how internal medicine gets billed — not a generic denial list copied across specialties.
- Sequencing Error
AWV billed out of order
Billing G0439 before a G0438 has ever been on file denies outright. G0438 billed a second time is an automatic denial — both are lifetime-tracking errors, not one-time mistakes.
- Audit Risk
E/M downcoding on review
Payers increasingly recoup 99214 claims when documentation shows a stable, routine-refill visit rather than the exacerbation or data review the code requires.
- Bundling
Modifier 25 disputes
Payers bundle the E/M into the preventive visit when the “separately identifiable” problem isn’t documented with its own assessment, even when the care was genuinely provided.
- Documentation Gap
CCM time logs incomplete
Chronic care management requires a documented care plan, patient consent, and at least 20 minutes of qualifying staff time per month — missing time logs are a leading CCM denial reason.
- Missed Window
TCM follow-up deadline missed
99495 requires a face-to-face visit within 14 days of discharge, 99496 within 7. Miss the window and the entire 30-day claim is unbillable, not just downgraded.
- Frequency Flag
New-vs-established miscoding
Billing a new-patient code for someone seen by the same specialty group within the last three years is a frequency error most clearinghouses won’t catch before submission.
- Payer Variance
Medicare Advantage prior-auth layering
Advantage plans frequently add documentation or prior-auth requirements on top of standard Medicare rules for imaging and referrals — standard workflows miss them.
- Medical Necessity
Unspecified ICD-10 coding
Ordering labs or imaging under a vague diagnosis code instead of the specific one supported by the chart is a leading cause of medical-necessity denials on ancillary services.
Our Process
How We Fix It: Our Internal Medicine Billing Process
Each step is built to catch the specific failure points above before they turn into a denial.
Verify eligibility and AWV history
Before the visit, we confirm active coverage and check whether a G0438 has ever been billed anywhere, so the correct wellness code goes out the first time.
Code and scrub every claim
E/M level, CCM/TCM code, and modifier selection are reviewed against the documentation before submission, not after a denial arrives.
Submit clean claims same-day
Completed encounters go out within an average 48-hour turnaround, keeping AR moving instead of stacking up.
Investigate every denial at the root
We identify whether a denial is a documentation gap, a sequencing error, or a payer-specific rule, and fix the pattern, not just the individual claim.
Work the AR on a set cadence
Aged claims are followed up on a schedule, not left to sit until they age past the point of recovery.
Report what actually matters
Clean claim rate, AR aging, denial rate, and CCM/AWV capture are tracked and shared with you every month.

Questions practice leaders ask before switching
Internal Medicine Billing Questions, Answered
How much does billing for internal medicine cost?
Pricing is based on your practice's visit volume, service mix, and current AR condition rather than a flat rate, since chronic care management and transitional care volume affect workload differently than office visits alone. We'll walk through your specific fee schedule during your free revenue review, with no obligation.
How long does onboarding take?
Most internal medicine practices are fully onboarded in under a week. We start with a free billing audit of your current claims, denial rates, and coding, then align our workflow to your existing processes before taking over live billing.
Can you take over our existing AR and open claims?
Yes. We review your current aged claims, prioritize what's still recoverable, and continue working them alongside new claims, so revenue already earned under your prior process isn't abandoned mid-cycle.
Do you bill Annual Wellness Visits and chronic care management correctly?
Yes. We track each Medicare patient's AWV history to bill G0438 or G0439 correctly, and we maintain the time logs, care plans, and consent documentation chronic and transitional care management require before submission.
How do you handle denials and appeals?
Every denial gets a root-cause review, not just a resubmission. We identify whether it's a documentation gap, a coding error, or a payer-specific rule, correct the claim, and file the appeal within the payer's deadline.
Is your billing process HIPAA compliant?
Yes. Every workflow we use to handle patient and claims data follows HIPAA requirements, and the coders and billers on your account are certified professionals working within those standards on every claim.
How do we track our numbers once you take over billing?
You receive monthly reporting on clean claim rate, AR aging, denial rate, and collections, along with a direct point of contact for questions, so you're not waiting on a year-end summary to know how billing is performing.
Do you work with internal medicine practices in every state?
Yes. As an internal medicine billing company working nationwide, we bill for practices across Medicare, Medicare Advantage, Medicaid, and commercial payers in all 50 states, whether you're a solo internist or a multi-location group.
