Find every dollar your coding misses.
Every code that drives outpatient internal medicine and medicine subspecialty revenue. When to use it, what to document, what gets denied, and how much it pays at your bonus rate.
What do you need?
Search by code, description, or specialty. Each code has its own page with when-to-use, documentation checklist, modifiers, and ICD-10 pairings.
See the top codes that drive revenue in your specialty, common visit scenarios, and the modifier rules unique to your practice setting.
Our AI auditor reads a vignette and tells you the right primary E/M, the add-ons you missed, the modifiers you need, and the dollars left on the table.
Codes that move the needle
Six codes worth re-reading if you bill outpatient E/M. Most underbilled in primary care.
Add-on to office E/M (99202-99215) when you are the continuing focal point for all needed care (primary care) OR the ongoing care provider for a single serious/complex condition.
The workhorse code. Two or more chronic problems with progression/treatment changes, OR one undiagnosed new problem with uncertain prognosis, OR prescription drug management.
Every year after the initial AWV. Cannot be billed within 12 months of the prior AWV.
Patient with mild cognitive impairment, dementia, or suspicion thereof. Once per 180 days.
Annual ASCVD risk calculation in patients without known ASCVD. New 2025 code; pairs naturally with AWV.
Discussion of advance directives, healthcare proxy, goals of care. Patient must be present at start unless meeting with a surrogate is explicitly billed.
By specialty
Top codes, common visit patterns, and modifier rules per medicine specialty.
The bread and butter: established office visits, new-patient workups, complex chronic disease bundles, and wellness add-ons. The codes that move primary care RVUs are E/M time/MDM, G2211, and the wellness stack.
Heavy on Medicare wellness, chronic care management, transitional care, advance care planning, cognitive assessment, and SDOH. These are time-based codes with strict documentation; getting the documentation right turns 20 minutes of phone work into real RVUs.
Mixed E/M plus high-volume diagnostic procedures: EKGs, echos, stress tests, Holters, device interrogations, vascular ultrasound. Most cardiology procedures split into professional, technical, and global components.
Cognitive specialty, mostly E/M. Procedural revenue comes from CGM interpretation, thyroid ultrasound and biopsy, and MNT supervision. CGM coding is a regulatory layer cake — get the time, sensor source, and patient setup right or the claim gets denied.
Procedure-heavy. Most outpatient GI revenue comes from upper and lower endoscopy with modifier-driven add-ons (biopsy, polypectomy, dilation). Screening vs diagnostic coding has different patient cost shares and modifier rules.
Office spirometry, pulmonary function testing, bronchoprovocation, sleep medicine. Spirometry is one of the most under-coded ancillaries in primary-care-adjacent practices because the bronchodilator add-on gets forgotten.
ESRD monthly capitation drives outpatient nephrology revenue (MCP, 90951-90970), plus CKD E/M, vascular access procedures, and home dialysis training. MCP coding is age-stratified and visit-frequency stratified.
Cognitive specialty with high-yield joint and soft tissue injections, plus chronic infusion management. Joint injection coding is anatomic-site stratified, and ultrasound guidance is its own bundled code.
Almost entirely cognitive. Revenue depends on accurate complexity coding (99214/99215 with G2211), outpatient infusion management, and prolonged service coding for long visits. Antimicrobial stewardship rounds are not billable.
Infusion-driven revenue dominates: chemotherapy administration codes are time-stratified and drug-type stratified, with strict hierarchy rules. Cognitive E/M with G2211 is critical for survivorship and chronic disease management.
Cognitive specialty with high-RVU diagnostic procedures: EEG, EMG/NCS, evoked potentials, cognitive assessment. Most procedures split into professional and technical components. Cognitive assessment care plan (99483) is one of the highest-RVU outpatient codes in medicine.
Three revenue pillars: percutaneous and intradermal allergy testing (per-test billing), immunotherapy preparation and administration (95115-95170), and biologic injection management. Testing codes are billed per-test, so unit counts matter.
