SPECIALTIES / INTERNAL MEDICINE

Internal Medicine Medical Billing Services

Internal medicine practices manage the most clinically complex patient panels in primary care — chronic conditions, multi-system disease, high-acuity visits, and a payer mix dominated by Medicare and Medicare Advantage. Your billing needs to match that complexity.

THE CHALLENGE

What's costing your internal medicine practice money right now?

E/M Downcoding

High-complexity visits (99214–99215) require precise documentation. Payers routinely downcode when notes don't fully support the level billed — and most billers miss the nuances that protect your revenue. We flag downcoding risk before claims go out, not after the denial arrives.

Underutilized Chronic Care Management

CCM codes (99490, 99491) are among the most frequently underbilled services in internal medicine. Most practices either don't capture eligible time or lack the workflow to bill it compliantly every month. We build that workflow for you.

Missed HCC / Risk Adjustment Capture

With Medicare Advantage making up a growing share of most internal medicine panels, incomplete HCC coding doesn't just cost a claim — it understates your patients' risk profile and suppresses your capitated revenue for the entire year. We audit chart documentation against active HCC categories so chronic conditions are captured accurately and completely, every encounter.

Transitional Care Billing Gaps

Post-discharge TCM codes (99495, 99496) are time-sensitive and documentation-heavy. Missed or late-filed TCM claims are a direct revenue loss for every patient you follow after a hospital stay. We track discharge notifications and file the moment documentation clears.

ICD-10 Specificity for Chronic Conditions

Hypertension, diabetes, CKD, COPD — internal medicine diagnoses demand specificity at every encounter. A non-specific or incorrect ICD-10 code triggers denials, understates acuity, and puts you at audit risk. Our coders are trained specifically on chronic-disease specificity requirements, not general ICD-10 basics.

Complex Payer Mix

Internal medicine panels skew heavily Medicare and Medicare Advantage, with each plan applying different coverage policies, prior authorization rules, and reimbursement schedules for the same visit. We track payer-specific rules by plan so your team isn't relearning them claim by claim.

Prior Authorization Delays

Specialist referrals, diagnostic imaging, and certain medications require pre-authorization — and delays create gaps in patient care and cash flow alike. We manage the prior auth queue proactively so approvals land before the appointment, not after.

WHAT WE DO

Our Services for Internal Medicine Practices

Billing built for the way internists actually practice. Every service is delivered by coders and A/R specialists with direct internal medicine experience — not generalists managing your account alongside pediatricians and orthopedic surgeons.

WHY RED HOUSE?

Three reasons internal medicine practices switch to us

Team and Culture

Specialized coders and account managers with deep internal medicine expertise — not generalists assigned to your account. Our team understands chronic-disease coding, HCC capture, and CCM/TCM workflows because it's what we work on daily, not occasionally.

Technology

Integrated clearinghouse leveraging AI, analytics, and RPA with HL7 integrations and denial tracking to rapidly identify revenue leakage — including HCC gap analysis and CCM/RPM time-tracking tools built for chronic-care-heavy panels. We integrate directly with the EHRs internal medicine practices actually run on: Epic, athenahealth, eClinicalWorks, and others.

Patient & Payor Management

Patient billing handled with empathy; payors managed with persistence — including the plan-by-plan prior authorization and Medicare Advantage rules that make internal medicine billing uniquely complex. You stay out of the middle.

"We had no idea how much CCM revenue we were leaving behind until Red House ran an audit. We were eligible to bill CCM for over a third of our patient panel and hadn't touched it. Within 90 days, that alone covered more than the cost of their service."

FAQ

Questions internal medicine practices ask us

Do you bill chronic care management compliantly?

Yes. CCM is one of the highest-yield, most consistently underbilled service lines in internal medicine. We audit your patient panel, identify qualifying chronic conditions, track clinical staff time, and build a monthly billing workflow so no eligible minute is lost. All documentation meets CMS compliance standards.

How do you handle high-complexity E/M coding?

Our coders are trained on both the 2021 AMA E/M guidelines and medical decision-making (MDM) criteria. We review visit documentation before submission, flag downcoding risk, and communicate directly with your clinical team when notes need strengthening — before the claim goes out.

Can you bill transitional care management for our discharged patients?

Yes. We track discharge notifications, prompt your team on follow-up timing, and file TCM claims the moment documentation is complete to protect the billing window.

Do you handle HCC coding and risk adjustment for Medicare Advantage patients?

Yes. We review chart documentation against active HCC categories each year to confirm chronic conditions are coded to the correct specificity, so your risk-adjusted revenue reflects the actual acuity of your panel, not an undercounted version of it.

How do you manage prior authorizations without slowing down patient care?

We track referral, imaging, and medication authorization requirements by payer, submit proactively, and follow up on pending requests so approvals are in hand before the appointment or fill date whenever possible — instead of causing delays after the fact.

How do you handle ICD-10 specificity for chronic conditions like diabetes and CKD?

Our coders are trained specifically on chronic-disease documentation requirements — staging, complications, and payer-specific specificity rules — so claims go out coded to the level your documentation actually supports, reducing denials and audit exposure.

Our patients are split across a dozen different Medicare Advantage plans — can you actually keep up with that?

That's the core of what we do for internal medicine practices. We track coverage policies, authorization rules, and reimbursement schedules by plan, so your team doesn't have to relearn the rules every time a different plan's patient walks in.
