3°COHORTE MÓDULO 4 SEMANA 1: Clase asincrónica A.P.M. Facundo Romero

Main ideas, concepts, and lessons

• Module purpose (Module 4: Auditing of Billing)

  • Explains why medical billing auditing is essential in Argentina’s health system.
  • Links auditing and correct coding/nomenclatures to the ability to defend scarce resources, avoid billing problems, and optimize health system financing.
  • Emphasizes that auditing is not only technical—it supports compliance, transparency, ethics, and efficiency.

• Core definition: medical billing auditing

  • A systematic process that evaluates issued invoices to ensure they are:
    • Accurate and compliant
    • Consistent with documentation
    • Properly coded according to the relevant nomenclature
  • Auditing verifies that diagnoses, procedures, treatments, and services match the supporting clinical and administrative records.
  • Invoices alone are not enough: they must be backed by supporting documentation.

• Supporting documentation is mandatory

  • Examples explicitly mentioned:
    • Patient medical history and summaries
    • Reports
    • Surgical sheet/templates
    • Complete anesthesia records
    • Other required records needed to justify billing and coding decisions

• Billing starts at the point of care

  • The process begins when a professional/institution provides care, from:
    • outpatient consultations to
    • complex surgical procedures.
  • Services must be coded using coding systems/nomenclatures (diagnostic coding is partly based on ICD—International Classification of Diseases).
  • Coding and invoicing occur per code assigned to each performed service, under regulation.

• Regulatory and oversight framework

  • Mentions key regulations/laws:
    • Law 24.901 (mental health law; clarifies inclusions/exclusions)
    • Law 26.682 (basic benefits for comprehensive health care)
  • The Superintendency of Health Services (Superintendencia de Servicios de Salud):
    • supervises health insurance providers
    • audits both service providers and financing entities
    • ensures transparency and compliance in billing and provision.

• Why auditing matters

  • Prevents:
    • deviations/findings
    • delays in collection
    • billing delays
    • debits
    • lost or rejected billing.
  • Quality auditing reduces errors and improves resource allocation.

Methodology and tools for medical billing auditing (detailed bullet list)

A) Audit approaches and information reviewed

• Random sample audit
  • Selects a representative sample of invoices (instead of auditing all).
  • Performs an in-depth audit to find patterns of:
    • errors and
    • fraud
  • Reviews supporting documentation and consistency, including:
    • patient records/medical history updates
    • completeness of surgical and anesthetic records
    • completeness of informed consent
    • consistency between:
      • what was billed and
      • what was actually used/performed.

B) Coding and tariff controls

• Coding correctness (“building the coding”)

  • Verify that the correct codes were assigned to the services provided.

• Tariffs and contractual agreement checks

  • Confirm tariffs are:
    • current
    • correct
    • not outdated
    • consistent with contract terms
  • Validate that billed services were actually provided.

C) Systems and automation tools (with cautions)

• Management and billing platforms

  • Software systems that:
    • store/upload medical and administrative data
    • automatically generate invoices/settlements assigned to professionals using codes.

• System validations

  • Platforms validate codes and fee rates, but:
    • codes and fee-rate data must be kept up to date

• Automatic audits

  • Some platforms offer automatic audit checks when properly parameterized.
  • Warning lesson: even the best system fails if the data loading process is incomplete or incorrect.
  • Key control principle:
    • load the “most information” correctly,
    • keep it updated,
    • maintain oversight/validation.

D) Common irregularities the audit aims to detect

• billing for services not provided
• overbilling
• duplicate billing
• coding errors
• omission of procedures
• missing supporting documentation
• incorrect rate/tariff usage
• incorrect or misapplied medical orders

Debits: definition and required management workflow

Debit definition

• A debit in medical billing = an adjustment/correction to a previously issued invoice due to detected errors, such as:
  • incorrect rates
  • incorrect codes/services charged
  • omitted supporting documentation

Common debit causes mentioned

• coding error
• incorrect tariff
• duplicate billing
• omission of/incorrect “medical order” (as referred to in the transcript)

Recommended debit management approach (implied steps)

• In each debit process:
  • identify the reason for the error/debit
  • record how/when the debit is issued
  • ensure notification occurs both ways (informing and being informed)
• Register the debit because:
  • annual statistical analysis should identify the main debit-generating reasons and institutional patterns
  • results should feed future training plans
• Provide feedback for continuous improvement rather than treating debits as isolated paperwork.

---

Continuous improvement strategies (people + process + controls)

• Ongoing training

  • Train staff and administrative personnel (e.g., billing clerk)
  • Emphasize correct administrative support by healthcare professionals

• Data completeness and required records

  • Avoid incomplete ERP/orders missing:
    • data
    • informed consent

• Control/validation systems

  • Use internal/regular audits
  • Randomly check findings and correct them
  • Use a non-punitive improvement mindset:
    • mistakes can be used to improve transparency, professional ethics, and reduce future errors

---

Nomenclatures: what they are and why they matter for auditing

Definition of a nomenclature (general)

• A health-services nomenclature is:
  • a list/compendium of medical practice codes
  • used by providers, doctors, clinics, funders, etc.
  • so billing to health agents is reasonable, orderly, coherent.

Public Hospitals with Decentralized Management nomenclature (HPGD)

• Central purpose:

  • standardize and detail medical services/procedures
  • define reference values (often lower than private agreements)
  • facilitate organization and control of budgets in public services.

• Rationale in the transcript:

  • Many patients using public services have private coverage (social/prepaid/cooperative/insurance).
  • The system aims to recover costs from the relevant health insurance agent when applicable.

• Auditing + nomenclature linkage:

  • auditors verify billing consistency using the nomenclature
  • billing calculation supports planning (billed vs settled amounts)

Structure characteristics described

• categorized by features including:
  • reference values
  • codes and descriptions for each feature

Insurance entities: roles in coverage and why auditing is essential

Definition

• Insurance entities are institutions that provide financial coverage to members to access health services without immediate out-of-pocket costs.

Types listed

• social welfare organizations
• private health insurance companies
• workers’ compensation insurers / occupational risk insurers (ARTs)

Coverage categories mentioned

• basic benefits (e.g., PMO—mandatory medical plan)
• extended/complementary benefits
• additional distinct services offered with extra cost/deductions
• direct payment/reimbursement to providers

Role of auditing in insurance entities

• Similar goal to other auditing contexts:
  • audit services for correctness
  • detect findings/errors
  • address them to increase:
    • quality of care
    • efficiency

Quality evaluation aspect

• Patient satisfaction surveys are used to evaluate patient perception.

---

PAMI nomenclature and equity concept

• PAMI: National Institute of Social Services for retirees and pensioners.

• The PAMI nomenclature is described as:

  • a compendium of services with codes and stipulated fees
  • standardizes mandatory care and improves transparency and fairness.

• Equity vs equality

  • Equity = provide resources to those who need them most.

• Coverage examples listed:

  • outpatient consultations and practices
  • high-complexity treatments
  • special high-cost medications (e.g., oncology medications, dialysis)

• Auditing role in PAMI:

  • ensures the billed service matches what was provided
  • ensures the service aligns with what should be provided to the beneficiary/subsidiary

---

Provincial nomenclatures (local differences) and CSPRA harmonization

• Each province has its own service list of medical services:

  • managed by provincial social welfare organizations and/or health ministries
  • adapted to local epidemiology, infrastructure, and regional characteristics

• Differences may include:

  • distinct codes from the national nomenclature
  • tariff variations by region

• Importance of “mixer”/agreement terms:

  • audits must follow regional coding rules and contractual annexes.

CSPRA involvement

• CSPRA = Provincial Social Works Commission of the Argentine Republic.
• Role described:
  • coordinate provincial social works
  • provide regulatory framework to unify criteria
  • harmonize and update nomenclatures with tariffs and coverage levels
  • standardize/homologate service codes
  • regulate fees/tariffs and oversee/control implementation

---

Anesthesiology nomenclature: auditing focus for patient safety

• Why it is important:

  • guarantees patient safety
  • includes anesthesia record and participation form with key data:
    • surgical risk level
    • patient status at start
    • what was used
    • final conditions on leaving procedure
    • recovery details and any special particularities.

• Auditing checks also include:

  • correct billing and compliance with regulations
  • required documentation for billing
  • quality/safety verification:
    • suitability of equipment
    • operating room conditions
    • biosafety standards (e.g., positive/negative pressure, filtered air)
    • infection control (infectious disease committee; postoperative infection indicators).

Examples of anesthesia procedure types mentioned

• local anesthesia
• regional anesthesia

• general anesthesia

• Need for consistency with surgical timing:

  • surgery start time and end time must match records

---

“Non-nomenclature practices” (non-listed services) and how they are handled

• Definition

  • services not included in national or agreed nomenclatures because they may be:
    • new, specialized, uncommon
    • not yet updated in the nomenclature
    • cutting-edge or experimental
    • needed for complex personalized clinical cases outside existing lists.

• Handling approach

  • requires agreement/negotiation with the health insurance agent
  • must be framed and formally coded for billing purposes.

• Challenge highlighted

  • Lack of specific codes means the requesting professional must justify medical necessity, using:
    • medical history summaries/copies
    • evidence-based medicine
    • compliance with each health agent’s rules for code request/submission.

---

Final conclusions / recommendations

• Medical billing auditing is a fundamental component of health service management:
  • Ensures fair remuneration and reduces fraud/administrative errors.
  • Optimizes scarce health resources.
• Nomenclature use is essential
  • not only for auditors but for the whole health management team.
• Recommendation:
  • pursue ongoing training and continuous education
  • stay up to date with changing regulatory frameworks
  • apply changes only after publication in the Official Gazette (avoid informal/unofficial updates)
