Internal Medicine Billing — Built for Your Practice
Internal medicine practices see complex patients with multiple chronic conditions — and they routinely underbill the E&M complexity they actually provide. The difference between a 99213 and a 99215 can be $150 per visit. Multiply that by 20 patients a day and the annual underbilling is staggering.
Our internal medicine billers use the 2021 AMA E&M guidelines to document medical decision-making and correctly level every encounter. We also capture every chronic care management code, transitional care code, and wellness visit that most practices miss.
Why Internal Medicine Billing Is Complex
Internal medicine billing complexity includes:
- E&M level selection under 2021 MDM guidelines
- Chronic Care Management (CCM) time-tracking requirements
- Annual Wellness Visit (AWV) vs. preventive vs. sick visit billing
- Transitional Care Management (TCM) codes after discharge
- Advance Care Planning codes and documentation requirements
- Hospital medicine admission/subsequent visit/discharge billing
- ✓ Specialty-specific denial prevention
- ✓ Certified coders trained on your CPT codes
- ✓ Payer-specific rules for Internal Medicine

Top Internal Medicine Claim Denial Reasons — and How We Eliminate Them
Most Internal Medicine denials are preventable. Our team knows exactly what to look for before submission.
❌ AWV vs. Preventive vs. Sick Visit Confusion
Billing Annual Wellness Visit and a preventive service on the same date without proper modifier results in denial of one visit.
✓ Our Fix
We correctly split AWV and significant separate E&M visits using modifier -25 when clinically and documentarily supported.
❌ CCM Without Required Documentation
Chronic Care Management requires a documented care plan, patient consent, and tracked time. Missing any element = denial.
✓ Our Fix
Our CCM billing workflow verifies consent, care plan documentation, and time tracking before submitting every monthly CCM claim.
❌ TCM Code Incorrect Day Requirements
TCM codes have specific day-from-discharge and communication requirements that are frequently violated.
✓ Our Fix
Our system tracks discharge dates and TCM deadlines automatically, flagging cases where TCM requirements haven't been met.
❌ E&M Downcoding by Payer
Payers routinely downcode high-complexity E&M visits claiming insufficient documentation. Most practices accept the downcode.
✓ Our Fix
We appeal every downcode with the specific documentation supporting the coded MDM level, and our overturn rate exceeds 80%.

The 2021 AMA E&M guidelines changed leveling from history/exam/MDM to MDM or total time. Our coders are trained on the current MDM-based leveling system and document the specific elements of medical decision-making for every encounter.
Yes, and this is one of the most commonly missed revenue opportunities in internal medicine. CCM (99490, 99491, 99487, 99489) reimburses $40–$130+ per patient per month for managing chronic conditions. We identify eligible patients and implement a CCM billing program for your practice.
Yes. TCM codes (99495, 99496) reimburse $140–$230 per discharge transition. Most practices miss these because the timing requirements are strict (contact within 2 business days, visit within 7 or 14 days). We track all discharges and flag TCM opportunities before the window closes.
AWV billing requires specific Medicare IPPE (Initial Preventive Physical Examination) and AWV codes that differ from standard preventive care codes. We bill the correct G-codes, capture all eligible add-on services, and ensure the beneficiary has only one AWV per calendar year to avoid duplicate billing issues.
Yes. Hospital medicine billing (admission codes 99221-99223, subsequent visit codes 99231-99233, discharge codes 99238-99239) requires different expertise from outpatient billing. Our hospital medicine billing team handles the full inpatient encounter spectrum.
