Outsourced Hospital Billing That Fails Differently Than Practice Billing.
Hospital revenue loss rarely comes from one big mistake. It comes from thousands of small ones: missed CC/MCCs, incorrect POA indicators, downcoded ED visits, and revenue code errors that quietly drain reimbursement every month. GenMediTech is a specialized hospital medical billing company providing outsourced hospital billing and hospital revenue cycle management solutions, built around the exact coding, compliance, and reimbursement requirements that keep hospital revenue protected at every level of care.

What Are Hospital Billing Services?
Hospital billing services manage the full hospital revenue cycle management process, including charge capture, facility coding, claim submission, payment posting, denial resolution, and A/R follow-up. The work spans inpatient DRG billing, outpatient APC and OPPS, and emergency department services, each with its own coding rules and payer requirements. Every setting requires a different discipline — and most revenue leaks happen when they are treated the same.

Inpatient claims follow DRG-based reimbursement. Outpatient claims follow APC and OPPS rules. Emergency department visits follow their own E&M leveling. Each is a separate billing discipline. Most hospital billing problems come from treating them the same way.
DRG Assigned at the Wrong Severity Level
MS-DRG assignment depends on the principal diagnosis, secondary diagnoses, procedures, discharge status, and documented complications. Our AI-assisted coding validation helps identify unsupported code combinations, documentation gaps, and potential undercoding before the facility claim is finalized.
POA Indicators Coded Incorrectly
Every diagnosis needs a Present on Admission indicator. Get it wrong, and a condition that should raise the DRG severity gets ignored, or a hospital-acquired condition gets paid as pre-existing. Both are audit triggers.
Observation vs Inpatient Misclassification
Medicare's two-midnight rule decides inpatient vs observation status. Wrong call either way means audit risk or lost reimbursement — and the difference in payment can be substantial.
ED E&M Levels Not Supported by Documentation
ED visits bill under five levels, 99281 through 99285. CPT 99283 and 99284 carry the highest volume. Undocumented MDM means downcoding, and at high ED volume, that adds up fast.
Charge Capture Gaps
OR procedures, ED visits, critical care, device implants. Missed supplies or undocumented procedures mean revenue lost before the claim ever exists. Gaps in the CDM compound this daily.
APC and OPPS Errors
Incorrect procedure grouping, missing status indicators, and device-intensive procedure errors mean systematic underpayment on outpatient services across every department.
Missing or Outdated Revenue Codes
Hospital claims run on the UB-04, not the CMS-1500. Every line needs a revenue code. 2026 NUBC updates tightened formatting for telehealth and remote monitoring codes, raising rejection risk for outdated mapping.
Our Hospital Billing Services:
Inpatient, Outpatient, and Facility Billing
Every engagement covers the full hospital billing stack — from DRG optimization and POA review to denial management and patient collections.
Inpatient DRG Billing and Optimization
Complete review of diagnoses, procedures, and documented complications. Every MCC and CC gets captured, maximizing legitimate DRG weight on every inpatient claim.
POA Indicator Review
Every diagnosis verified against documentation for correct POA status. Hospital-acquired conditions flagged correctly, pre-existing conditions never miscoded — audit-ready before the claim goes out.
Outpatient APC and OPPS Billing
Outpatient facility claims are reviewed against the current CMS Hospital Outpatient Prospective Payment System, including APC assignments, status indicators, packaging rules, and device-intensive procedure requirements.
Emergency Department Billing
ED E&M levels are assigned from documented medical decision-making, critical care under 99291 is billed correctly, and modifier 25 requirements are reviewed whenever a significant, separately identifiable E&M service occurs on the same day as another procedure.
Observation vs Inpatient Status Management
Admission status is reviewed against the physician's documented expectation, medical necessity, length of stay, and the latest CMS inpatient-status review guidance before the claim is assigned to inpatient or observation billing.
Charge Capture, CDM, and Revenue Code Management
Charges are reconciled across departments, while high-cost devices, implants, procedure codes, and revenue codes are validated before the UB-04 is transmitted. A structured process for claim scrubbing before submission helps catch invalid code combinations, missing fields, outdated mappings, and payer-specific errors before they trigger rejections.
Hospitalist Medical Billing
Daily inpatient E&M visits, 99231 through 99233, discharge management, and critical care billed correctly across every payer without downcoding or missed levels.
Hospital AR and Patient Collections
AR worked by aging bucket, payer, and service line, with high-value inpatient claims prioritized. Patient balances handled with clear statements and Good Faith Estimate compliance under the No Surprises Act.
Denial Management and Appeals
Every denial is traced to its root cause, including DRG assignment, patient status, revenue-code mapping, authorization, or documentation. Claims requiring extended payer follow-up, correction, appeal, or resubmission move through our hospital A/R and denial management workflow until they are resolved.

Frequently Asked Questions
Common questions about hospital billing, MS-DRG, POA indicators, and the two-midnight rule.
What is the difference between hospital billing and physician billing?
Hospital billing covers facility charges on a UB-04. Physician billing covers professional services on a CMS-1500. Different coding systems, different reimbursement rules, different compliance requirements — they cannot be managed the same way.
What is MS-DRG and why does it matter for inpatient billing?
MS-DRG is the payment system Medicare uses for inpatient claims. It sets a flat rate per stay based on diagnoses, procedures, POA indicators, and documented complications — regardless of actual cost. Missed comorbidities mean lower DRG severity and systematic underpayment on every affected stay.
What is a POA indicator and why does it affect reimbursement?
A POA indicator tells Medicare whether a condition existed before admission or developed during the stay. Hospital-acquired conditions do not count toward a higher DRG and can trigger payment reductions. Required on all IPPS claims and a frequent Recovery Audit Contractor target.
What is the two-midnight rule?
Inpatient admission is appropriate when a physician expects care to span at least two midnights. Below that threshold, the patient should be in observation, billed differently and at a lower rate. Misclassification in either direction creates audit risk or lost reimbursement.
What is a Charge Description Master?
The CDM is a database of every billable service, supply, and procedure your hospital provides, with its revenue code, CPT code, and charge. An outdated CDM means missed charges and wrong revenue codes — creating losses before any claim is even submitted.
Do you handle both inpatient and outpatient hospital billing?
Yes. DRG, APC, OPPS, ED, observation, and hospitalist billing — all under one team. No hand-offs between departments, no gaps between service lines.
Does the No Surprises Act apply to hospital billing?
Yes. Hospitals must provide Good Faith Estimates for self-pay and uninsured patients and follow federal independent dispute resolution rules for certain out-of-network claims. We handle compliance on every patient balance.
What happens when a hospital claim gets denied?
We identify the exact reason — DRG error, status issue, revenue code error, authorization gap — correct it, and resubmit with proper documentation. Complex denials get formal appeals with clinical evidence attached.
Is our patient data secure?
Yes. HIPAA-compliant workflows, encrypted data, controlled access at every step. GenMediTech operates under a signed BAA with every hospital partner.
Hospital Revenue Lost to Billing Errors Does Not Show Up as One Big Number. It Shows Up as Thousands of Small Ones.
Missed comorbidities. Incorrect POA indicators. Downcoded ED visits. Misclassified admissions. Missing revenue codes. Each one looks manageable. Together they represent millions in systematic underpayment your hospital absorbs every year.
