Hospital Billing Services

Institutional billing operates in a fundamentally different universe than professional physician billing. We bridge the structural complexities of UB-04 and 837I claims, dual prospective payment systems, and comprehensive chargemaster oversight to protect earned facility revenue.

How Can Medical Billing Data Support Your Practice Growth?

Medical billing is not just paperwork-it is the financial heartbeat of your practice. When denial patterns, reimbursement velocity, and payer contracts are visible in real time, practice leadership can make informed staffing and clinical decisions.

PNW provides scheduled executive dashboards, transparent collections reporting, and proactive consultation to keep your practice financially sound.

One Admission Collapses into One MS-DRG

Under the Inpatient Prospective Payment System (IPPS), an entire hospital stay is reimbursed as a predetermined lump-sum weight based on the assigned Medicare Severity Diagnosis Related Group (MS-DRG), regardless of the actual line charges incurred.

Principal Diagnosis & Procedures: Coded using ICD-10-CM and ICD-10-PCS to establish the primary clinical reason for admission.
CC / MCC Comorbidity Capture:The primary lever that shifts a DRG into higher reimbursement is documenting supported complications (CC) or major complications (MCC).
Discharge Status Codes:Post-acute transfer rules require accurate discharge status (e.g., home health, skilled nursing) to prevent per-diem payment downgrades.
Present on Admission (POA):Distinguishing pre-existing conditions from hospital-acquired conditions (HAC) to avoid non-payment penalties.

Line-by-Line Packaging Under Ambulatory Payment Classifications

Under the Outpatient Prospective Payment System (OPPS), services provided in emergency departments, observation units, and hospital outpatient departments are categorized into Ambulatory Payment Classifications (APCs) governed by complex packaging rules.

Status Indicators (SI):Determine whether a service is paid separately (S, T, V), packaged into another service (N), or paid under a clinical lab fee schedule.
Comprehensive APCs (C-APCs):J1 and J2 indicators automatically bundle almost all secondary adjunctive outpatient services into a single primary encounter payment.
Observation Services (Rev Code 0762):Requiring HCPCS G0378 with precise start/stop hours to cross the 8-hour threshold for composite APC adjudication.
NCCI & PTP Edits:Preventing unbundling errors and validating applicable modifier usage (such as modifier 59 or XE/XP/XS/XU) on hospital claims.

Core Institutional Claim Fields (UB-04 / 837I)

The institutional code sets that determine whether a facility claim processes cleanly on the first pass or gets rejected.

Revenue Codes

Four-digit numbers (e.g., 0450 Emergency Room, 0360 Operating Room, 0762 Observation) identifying where or how care was administered.

Condition Codes

Flags indicating special circumstances, such as Condition Code 44 for changing inpatient orders to outpatient observation before discharge.

Occurrence Codes

Specific event dates (accident dates, onset of symptoms, insurance retirement dates) paired with date fields required for coordination of benefits.

Value Codes

Monetary amounts and quantifiable figures required by Medicare (such as blood pints administered, lifetime reserve days, or working aged amounts).

Discharge Status

Two-digit status code defining patient disposition (e.g., 01 routine home, 02 other short-term hospital, 03 SNF) regulating DRG transfer calculations.

POA Flags

Present on Admission indicator flags (Y, N, U, W, 1) assigned to secondary diagnoses ensuring legitimate comorbidities are reimbursed.

ICD-10-PCS

Seven-character procedural coding system used exclusively for inpatient hospital facility claims to capture surgical and inpatient interventions.

Electronic 837I

The HIPAA standard EDI transaction set used to transmit institutional UB-04 data electronically directly to clearinghouses and payers.

Where Hospital Revenue Cycle Problems Can Occur

Facility revenue loss frequently stems from structural workflow disconnects rather than overt clinical rejections.

Incomplete Charge Capture

Delivered bedside nursing, surgical trays, or pharmacy items never charged in the EHR. Because no claim was ever billed, no denial occurs to alert management.

Thin Documentation & Downgrades

A clinical record that supported a higher-weighted MS-DRG but lacked explicit physician diagnostic linkage, causing silent underpayment upon adjudication.

Two-Midnight Status Discrepancies

Inpatient admissions that fail to meet the two-midnight benchmark without documented clinical expectation, triggering post-payment RAC recoupments.

Outpatient OPPS Packaging Errors

Incorrect revenue-to-HCPCS pairing causing separately payable outpatient items to be mistakenly bundled or unbundled into billing compliance edits.

Underpayment on Contract Allowables

Accepting commercial remittance payments at face value without validating payments against negotiated per-diem or case-rate contract schedules.

Aging Facility Receivables

High-dollar institutional claims stalled in pending review without active payer outreach until filing deadlines or timely appeal clocks expire.

Not Every Revenue Cycle Problem Appears as a Denial.

A standard denial report only reveals what payers have actively rejected. The most costly revenue losses in hospitals occur silently – where delivered services were never charged, chargemaster rates remained outdated, or admissions were billed under a lower DRG tier than the medical chart justified.

Addressing these vulnerabilities requires proactive charge reconciliation, ongoing chargemaster maintenance, and disciplined clinical documentation queries before claims leave the hospital.

Why Charge-Capture Leakage Evades Notice

NO DENIAL

Unbilled care generates zero remittance rejection

NO REPORT

Standard analytics only monitor submitted claims

SOLUTION

Reconciliation between clinical schedules & billed items

Where Hospital Revenue Cycle Problems Can Occur

Facility revenue loss frequently stems from structural workflow disconnects rather than overt clinical rejections.

01 Eligibility & Authorization

Verification of commercial and government coverage, inpatient pre-certification, and observation notifications prior to elective admission.

02 Documentation & Coding

Certified facility coders assigning ICD-10-CM/PCS and HCPCS, validating CC/MCC comorbidity capture and establishing POA indicators.

03 Charge Capture & Claim Review

Reconciliation between clinical charting and chargemaster entries. Scrubbing claims against Medicare institutional edits before transmission.

04 Claims Submission

Electronic 837I transmission to institutional clearinghouses and primary, secondary, and tertiary payers with immediate tracking of electronic confirmations.

05 Denial & A/R Follow-Up

Systematic appeal of medical necessity denials and DRG downgrades on the clinical record. Rigorous follow-up on aged facility accounts.

06 Posting & Reconciliation

Electronic remittance advice (ERA/835) posting, variance checking against contracted rates, and operational trend reporting for facility administrators.
