Hospital Billing

Hospital billing operates in a completely different regulatory universe from physician billing. UB-04 claims, DRG optimization, revenue codes, condition codes β€” it requires specialists who live in this world daily.

Inpatient vs. Outpatient: Different Rules, Different Expertise

These two billing environments have entirely separate code sets, claim forms, and reimbursement structures. We are experts in both.

Inpatient Hospital Billing

CMS-1450 (UB-04) Β· ICD-10-PCS Β· DRG-Based Reimbursement

Inpatient billing is complex, high-value, and DRG (Diagnosis-Related Group) driven. A single MS-DRG assignment can be worth $15,000–$80,000+ per admission. Accurate principal diagnosis selection and ICD-10-PCS procedure coding directly determines your DRG weight β€” and therefore your entire reimbursement for that stay.

  • Principal diagnosis optimization for correct DRG assignment
  • CC/MCC (Complication & Comorbidity) documentation capture
  • ICD-10-PCS procedure coding for surgical inpatient stays
  • UB-04 revenue code assignment and charge master reconciliation

Outpatient Hospital Billing

CMS-1450 (UB-04) Β· APC-Based Β· OPPS Rules

Hospital Outpatient Prospective Payment System (HOPD) billing is governed by Ambulatory Payment Classifications (APCs) and strict CMS bundling rules. Packaging rules, composite APCs, and status indicator assignments all affect payment β€” and non-compliance creates significant audit risk.

  • APC assignment optimization and status indicator review
  • Observation vs. inpatient status decision support
  • Emergency department E&M and critical care coding
  • OPPS packaging rule compliance to prevent RAC audit triggers

Revenue Intelligence

Every Admission Is a Revenue Opportunity

Hospital billing is unlike any other healthcare billing environment. The dollars involved per claim are significantly higher, the compliance risk is greater, and the complexity of charge capture β€” across dozens of departments β€” makes revenue leakage almost inevitable without specialized oversight.

Our hospital billing specialists conduct concurrent chart reviews during patient stays to identify documentation gaps before discharge β€” not after, when it's too late to amend the record.

Charge Master Reconciliation

We review and reconcile your charge master (CDM) annually to ensure all billable services map to current revenue codes and CPT codes β€” preventing systematic under-billing.

Clinical Query Program

We facilitate compliant physician queries to clarify documentation that supports higher-weighted DRGs β€” adding specificity without altering clinical facts.

Denial Prevention Protocol

Hospital claims are high-value targets for payer audits and RAC reviews. We pre-screen high-risk DRGs before submission to prevent costly post-payment retractions.
