Expert internal medicine billing and coding for internists, hospitalists, and adult medicine groups in Las Vegas, Henderson, Reno, and across Nevada.
Internists treat the most complex adult patients, and payers scrutinize those claims the hardest. Nevada Medical Billing helps internal medicine practices get paid in full for high-level E/M visits, hospital and nursing facility rounds, chronic care management, and in-office diagnostics. We handle coding, claims, denials, and A/R follow-up for Medicare, Medicare Advantage, Nevada Medicaid managed care, and commercial plans.
We'll review 90 days of your claims and show where revenue is leaking. No cost, no obligation.
Internal medicine claims carry more diagnoses, more settings, and more payer scrutiny than almost any other outpatient specialty. One visit for a patient with diabetes, CKD, heart failure, and depression must be coded to the right complexity, linked to the right diagnoses, and supported by documentation that survives an audit.
Nevada has 1,525 active internists and needs about 316 more to match the national rate, according to the Nevada Health Authority's 2026 workforce assessment. Busy internists document fast, and fast documentation is where E/M levels and HCC codes get missed.
Internists bill more 99214 and 99215 visits than most specialties because their patients are complex. Payers know this and target those codes with downcoding and record requests. Every level must be supported by medical decision making (MDM) or total time.
Many Nevada internists see patients in the office, round at hospitals like UMC Southern Nevada or Renown Regional Medical Center, and visit skilled nursing facilities. Each setting has its own code family, place-of-service rules, and frequency limits. Missed hospital and nursing home charges are one of the biggest revenue leaks we find.
Internists care for many Medicare and Medicare Advantage patients. MA plans pay based on documented risk under CMS-HCC V28. If chronic conditions aren't documented and coded every calendar year, your RAF scores, and your value-based payments, drop.
Since January 2026, Nevada Medicaid managed care covers all counties. Internists treating adult Medicaid patients may now bill up to five MCOs, each with separate credentialing, authorization, and timely filing rules.
99214/99215 visits downcoded because MDM isn't clearly documented
Hospital, observation, and SNF visits never entered as charges
Split/shared visits billed under the wrong provider or without modifier FS
CCM and TCM time tracked but never billed
G2211 missed on eligible Medicare visits
HCC conditions not recaptured each year
In-office EKGs, spirometry, injections, and CLIA-waived labs left off the claim
Modifier 25 missing when a procedure and E/M happen on the same day
We run the complete internal medicine revenue cycle, in the office and outside it. Pick full-service RCM or the modules you need.
We collect and reconcile charges from every place you practice: clinic, hospital, observation unit, skilled nursing facility, and telehealth. Daily census and rounding-list reconciliation means no hospital or nursing home visit goes unbilled.
Certified coders assign CPT, ICD-10-CM, and HCPCS codes based on MDM or total time. We run periodic E/M audits that show your level distribution against peers, so you're neither undercoding nor exposed to audit risk. Medical Coding
Our CRC-certified coders review charts for complete, MEAT-supported HCC capture under CMS-HCC V28. We flag suspected conditions for provider review and track annual recapture across your Medicare Advantage panel.
We verify coverage, MA plan, and Medicaid MCO before each visit. Eligibility Verification
We handle authorizations for imaging, specialty drugs, infusions, and referrals across Medicare Advantage, Medicaid MCOs, and commercial plans. Prior Authorization
Claims pass payer-specific edits, NCCI checks, and LCD/NCD medical necessity checks before submission, usually within 24–48 hours of the visit.
We post ERAs line by line and compare every payment to your contracted fee schedule. Payment Posting
We appeal E/M downcoding, medical necessity, and bundling denials with documentation support, then fix the root cause. Denial Management
We work aged claims by value and timely filing risk, including legacy A/R from a previous biller. AR Follow-Up
We enroll internists, hospitalists, NPs, and PAs with Medicare, Nevada Medicaid, every MCO, and commercial payers, and keep CAQH current. Credentialing
Clear statements, payment plans, and a patient billing line that protects your patient relationships. Patient Billing
We help capture quality data codes and track MIPS performance so you avoid negative Medicare payment adjustments.
Collections, days in A/R, denial rate, E/M distribution, and payer mix, by provider and location. Revenue Cycle Management
Our coders know the internist code set end to end, from a 99215 in clinic to a nursing facility discharge.

Under current E/M rules, office visit levels rest on MDM (problems, data, risk) or total time on the date of service. We code what the note supports, educate providers on documentation gaps, and track your 99214/99215 distribution so you're not an outlier.
When NPs or PAs share a visit with a physician, the substantive portion decides who bills. We apply modifier FS for split/shared hospital visits and follow incident-to rules in the office, so you get the 100% physician rate only when it's allowed.
We use modifier 25 for significant, separate E/M services on procedure days, 59 or X{EPSU} for distinct services, QW for CLIA-waived tests, and 95 for telehealth where required.
We code diabetes with complications, CKD stage, heart failure type, COPD, morbid obesity, and major depression to full specificity. This supports medical necessity, protects against RADV audits, and keeps RAF scores accurate.
