Specialties

Pick a specialty for top-billed codes, common visit scenarios, and modifier rules tailored to that practice setting.

Outpatient IM
Internal Medicine

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.

Geri / CCM
Geriatrics & Care Management

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.

Cardiology
Cardiology

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.

Endo
Endocrinology

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.

GI
Gastroenterology

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.

992149921545378453804538545381+4
Pulm
Pulmonology

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.

Nephro
Nephrology

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.

992149921590951909549095790960+4
Rheum
Rheumatology

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.

9921499215G2211206102061120605+4
ID
Infectious Disease

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.

99204992059921499215G221199417+4
Heme/Onc
Hematology / Oncology

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.

9920599215G2211964139641596417+4
Neurology
Neurology

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.

99204992059921499215G221199483+4
Allergy
Allergy / Immunology

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.
