Hospital internal audit checklist.

Hospital internal audit must connect clinical operations to revenue and control evidence. The file should tie admissions, discharge billing, TPA claims, pharmacy, consumables, OT, diagnostics, doctor payouts, biomedical assets, cash, compliance and HIS access into one RCM.

  • Reconcile OT register to patient bills

  • Review cancelled tests and procedure reversals
  • Test interface exceptions
Evidence

OT register, procedure notes, lab/radiology order, test completion report, billing extract, cancellation log and interface report.

Doctor payouts, referral fees and consultant contracts

Risk: Consultant payouts, retainers, revenue share, incentives or referral arrangements are computed incorrectly or outside approved contracts.

Controls
  • Approved consultant contract
  • Payout computation review
  • Referral/marketing policy
  • TDS and GST review
Tests
  • Recompute selected doctor payouts against contract terms
  • Match procedure revenue to payout base
  • Review manual adjustments and exceptions
  • Tie TDS/GST treatment to payout support
Evidence

Consultant contract, payout working, procedure revenue report, adjustment approval, TDS working, GST invoice/support and payment proof.

Cash, deposits, refunds and receivables

Risk: Patient deposits, cash collections, refunds, credit bills or old receivables are not reconciled or authorised.

Controls
  • Daily cash count
  • Deposit ledger review
  • Refund approval matrix
  • Receivables ageing review
Tests
  • Reconcile cash/card/UPI receipts to bills and bank
  • Test patient deposit adjustments and refunds
  • Age credit bills and TPA receivables
  • Review write-offs and waivers
Evidence

Cash count, receipt register, bank statement, patient deposit ledger, refund note, ageing report, write-off approval and waiver support.

Biomedical equipment, capex and maintenance

Risk: Medical equipment, AMC/CMC, calibration, downtime, capex or asset tagging is not controlled, affecting service continuity and asset records.

Controls
  • Capex approval
  • Asset tagging
  • AMC/CMC tracker
  • Calibration and downtime log
Tests
  • Match biomedical asset register to physical equipment
  • Review calibration and preventive maintenance status
  • Test capex approvals and capitalisation
  • Inspect downtime and service reports
Evidence

Capex approval, invoice, installation report, fixed asset register, asset tag, AMC/CMC contract, calibration certificate and downtime log.

Compliance, patient data and ITGC

Risk: Licences, statutory registers, HIS access, billing master changes or patient-data access are not controlled or evidenced.

Controls
  • Licence and compliance calendar
  • HIS role-based access
  • Billing master change approval
  • Audit-log review
Tests
  • Review licence/compliance tracker and renewals
  • Test HIS/POS users, leavers and privileged access
  • Sample billing/tariff master changes
  • Inspect audit logs for sensitive patient/billing activity
Evidence

Licence tracker, statutory returns, HIS user list, role matrix, leaver list, master change log, UAT approval and audit-log extract.

Continuous monitoring

Hospital rules worth automating rules

RuleException logic
Unbilled serviceOT, lab, radiology, pharmacy or consumable issue exists without matching patient bill line.
Claim ageingTPA, insurer or government-scheme claim remains unsubmitted, rejected or unsettled beyond threshold.
Refund anomalyRefunds, waivers or discounts cluster by cashier, doctor, department, package or approval user.
Expired stockMedicine, implant or consumable batch is expired, near expiry or written off without approved reason.
Doctor payout exceptionConsultant payout differs from contract formula, approved rate or eligible revenue base.
HIS leaver accessExited or transferred user remains active in HIS, billing, pharmacy or finance system.

FAQ

Hospital internal audit FAQs questions

What should a hospital internal audit cover?

A hospital internal audit should cover patient registration, admissions, discharge billing, tariff and package controls, TPA/insurance/government-scheme claims, pharmacy and consumables, OT/diagnostics revenue, doctor payouts, cash/refunds, biomedical assets, compliance, patient-data access and ITGC.

How is hospital internal audit different from a normal finance audit?

Hospital internal audit must connect operational records to financial records. OT registers, lab orders, pharmacy issues, discharge summaries, TPA claims and consultant contracts are as important as ledgers because revenue leakage and compliance gaps often begin before accounting entry.

Which hospital audit checks are best for continuous monitoring?

Useful recurring checks include unbilled OT/lab/pharmacy services, old TPA claim ageing, rejected claims, unusual refunds or discounts, expired stock, high-value implant movement, doctor payout variances and leaver access in HIS or billing systems.

Can this checklist be used for clinics and diagnostic centres?

Yes, but tailor it. A clinic may remove OT and inpatient sections, while a diagnostic centre should go deeper on order-to-test-to-report-to-bill matching, sample handling, machine utilisation, refunds, packages and referral/doctor payout controls.
