What is Physician Medical Billing?

Physician medical billing is defined as the process by which healthcare providers are reimbursed for services delivered to patients. This process is governed by standardized coding systems, payer-specific rules, and compliance regulations issued by both government and commercial payers.

Each encounter between a physician and a patient must be documented accurately within the medical record. From this documentation, specific diagnosis codes (ICD-10) and procedure codes (CPT or HCPCS) must be abstracted. These codes are then used to generate claims that are submitted to insurance companies.

The claims are reviewed by payers for completeness, coding accuracy, and medical necessity. If the codes submitted do not support the service rendered or fail to justify the treatment based on clinical evidence, reimbursement may be reduced or denied entirely.

Physician billing encompasses both professional services and evaluation and management (E/M) components. Unlike facility billing, which includes technical services, physician billing focuses solely on provider effort, skill, and time spent. Relative Value Units (RVUs) are often applied to determine the provider’s compensation based on the complexity and intensity of services.

Timely submission and accuracy of these claims impact not only revenue flow but also audit risk and payer trust. Payers rely on the billing data to validate treatment relevance and cost-efficiency. Inconsistent billing patterns or overuse of high-level codes can trigger payer audits or recoupment requests.

How Does the Physician Medical Billing Process Work?

The physician medical billing process follows a structured, multi-step workflow that begins with patient registration and ends with final reimbursement or denial.

1. Patient Registration and Insurance Verification
The process begins when a patient schedules an appointment. Demographic information, insurance details, and payer coverage are recorded. Insurance eligibility is verified in real time to confirm active status, plan limits, and co-payment requirements. Failure at this stage can result in denied claims later due to coverage issues.

2. Clinical Documentation
After the visit, the physician documents the encounter. This includes the patient’s chief complaint, history, diagnosis, procedures performed, and follow-up care. Proper documentation is essential as it directly supports the medical necessity of billed services.

3. Medical Coding
Certified coders extract diagnostic codes (ICD-10), procedural codes (CPT/HCPCS), and any applicable modifiers. These codes must be accurate and specific. Incorrect code combinations, undercoding, or upcoding can lead to claim rejection or audit flags.

4. Charge Entry and Claim Creation
Charges are assigned based on coded data and entered into the billing software. A claim is generated, structured in ANSI X12 837 format, containing patient data, provider credentials, service details, and charge amounts.

5. Claim Scrubbing and Submission
Claims undergo automated validation via claim scrubbing tools that detect common errors like missing modifiers or mismatched diagnosis-to-procedure codes. Clean claims are submitted electronically to payers through clearinghouses or directly via payer portals.

6. Payer Review and Adjudication
Payers receive claims and begin adjudication. They assess medical necessity, coding accuracy, patient eligibility, and fee schedule alignment. Reimbursement is approved, adjusted, or denied based on contractual agreements and coverage policies.

7. Payment Posting and Denial Management
Approved claims generate Electronic Remittance Advices (ERA). Payments are posted against the patient’s account. Denials are categorized (e.g., coding error, eligibility issue, authorization lapse), and appeals are initiated when appropriate.

8. Patient Billing and Follow-Up
Any patient responsibility (deductibles, co-insurance, non-covered services) is billed. Accounts receivable staff follows up on unpaid balances or resubmits corrected claims for denied charges.

9. Reporting and Compliance Audits
Billing activity is monitored through key metrics such as Days in A/R, denial rates, and first-pass resolution rate. Periodic internal audits ensure coding compliance, charge integrity, and HIPAA security.

Common CPT Codes Used in Physician Medical Billing

Current Procedural Terminology (CPT) codes are central to Physician Medical Billing, defining the medical, surgical, and diagnostic services provided by physicians. These codes standardize billing and enable accurate reimbursement from insurance payers. CPT codes are maintained by the American Medical Association (AMA) and are revised annually to reflect new procedures, changes in technology, and evolving clinical practices.

CPT codes used in physician billing services are categorized into three types: Category I, Category II, and Category III.

Category I CPT Codes

These codes represent the bulk of procedures billed by physicians. Each code is five digits and grouped into six main sections:

• Evaluation and Management (E/M) codes (99202–99499)
  Used to bill for office visits, consultations, and hospital rounds. These are among the most frequently used codes in Physician Medical Billing, as they cover routine patient encounters. Code selection depends on complexity, time spent, and medical decision-making level.

• Surgery (10004–69990)
  Covers a wide range of surgical interventions, from minor excisions to major operations. Modifiers like -50 (bilateral procedure) or -59 (distinct procedural service) are often appended for claim specificity.

• Radiology (70010–79999)
  Includes diagnostic imaging services such as X-rays, CT scans, and MRIs. Radiology CPTs are supported by ICD-10 codes that confirm the necessity of imaging based on clinical symptoms.

• Pathology and Laboratory (80047–89398)
  Encompasses blood tests, cultures, biopsies, and molecular diagnostics. These codes often require CLIA compliance and must align with national coverage determinations (NCDs).

• Medicine (90281–99607)
  Used for non-surgical services like immunizations, infusions, and psychiatric evaluations. Some medicine codes require documentation of time duration, such as infusions billed in 15-minute increments.

Category II CPT Codes

These are supplemental tracking codes used for performance measurement and quality reporting under value-based care initiatives. They are alphanumeric and typically end with an “F” (e.g., 1123F). While not reimbursed directly, they help fulfill MIPS or HEDIS reporting requirements.

Category III CPT Codes

These are temporary codes for emerging technologies, procedures, and services. They allow for data collection before a service becomes eligible for Category I status. These codes begin with a zero (e.g., 0075T). Inclusion in Physician Medical Billing systems allows providers to track innovation-related services even if payer coverage is limited.

Code pairing rules, payer-specific edits, and modifier usage are critical when applying CPT codes. All CPTs must be linked to a medically necessary diagnosis, and codes must reflect the exact services rendered to avoid denials, audits, or payment delays.

​In Physician Medical Billing, accurate use of ICD-10 codes is crucial for proper documentation and reimbursement. Below is a comprehensive table of ICD-10 codes commonly encountered in physician services, along with their descriptions.

This selection encompasses a range of conditions and scenarios pertinent to physician services. For a complete and detailed list of ICD-10 codes, resources such as the Centers for Medicare & Medicaid Services (CMS) ICD-10 page that offer comprehensive and up-to-date information.

Insurance and Reimbursement Policies Governing Physician Medical Billing

1.0 Medicare Part B Reimbursement Policy Framework

Physician Medical Billing under Medicare Part B operates within the CMS-administered Resource-Based Relative Value Scale (RBRVS) system. Each physician service is assigned a Relative Value Unit (RVU) based on:

• Physician work

• Practice expense

• Professional liability insurance

The formula:
Payment = [(RVU work × Work GPCI) + (RVU PE × PE GPCI) + (RVU PLI × PLI GPCI)] × Conversion Factor

The annual Conversion Factor, determined by CMS via the Final Rule publication, directly influences allowed reimbursements. Physicians are mandated to bill using CPT/HCPCS codes, aligned with ICD-10-CM diagnoses to support medical necessity.

Documentation Standards:

• CMS E/M Guidelines (2021) dictate that time-based or medical decision-making criteria may be used.

• Claims are subject to National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs), enforceable by Medicare Administrative Contractors (MACs).

2.0 Medicaid Physician Billing Requirements (State-Dependent)

Each U.S. state operates its own Medicaid State Plan, with physician billing policies published via state provider manuals. Variations include:

• Accepted procedure codes (CPT/HCPCS)

• EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) billing frameworks

• Telemedicine codes and POS requirements

• Reimbursement methodology: Fee-for-Service (FFS) or Managed Medicaid Organization (MMO)

Example:
In Texas, the Texas Medicaid Provider Procedures Manual outlines prior authorization protocols and separate reimbursement rates for in-office procedures versus facility-based care.

3.0 Private Payer Contractual Billing Terms

Physician Medical Billing for private payers is governed by individually negotiated provider agreements. These contracts outline:

• Fee schedules (proprietary, not public)

• Medical necessity definitions (specific to the payer)

Insurance and Reimbursement Policies Governing Physician Medical Billing

1.0 Medicare Reimbursement Guidelines

Medicare Part B provides coverage for a wide range of physician services, with reimbursement based on the Resource-Based Relative Value Scale (RBRVS) system. This system assigns a Relative Value Unit (RVU) to each service, factoring in:

• Physician work: The time, mental effort, and technical skill required.

• Practice expense: The cost of supplies, equipment, and office overhead.

• Professional liability insurance: The cost of insurance for the service.

Medicare uses the RVU system to calculate reimbursements for physician services. The formula used is:

Payment = [(Work RVU × Work GPCI) + (Practice Expense RVU × PE GPCI) + (PLI RVU × PLI GPCI)] × Conversion Factor

The Conversion Factor (CF) is a fixed dollar amount that adjusts each year, as defined by CMS in the Final Rule. These values determine how much the physician will be reimbursed for services provided under Medicare Part B.

Note: It’s crucial for physicians to use the correct CPT codes and match them with ICD-10 codes to document medical necessity for services provided. Incorrect coding or incomplete documentation may lead to denials or audits.

2.0 Medicaid Billing Standards

Each state has its own Medicaid billing policies, as governed by state-specific Medicaid plans. These plans establish:

• The services covered by Medicaid

• The reimbursement rates for physician services

• Prior authorization and documentation requirements for certain services

• Guidelines for telemedicine and outpatient services

State Medicaid programs operate on either Fee-for-Service (FFS) models or through Managed Medicaid Organizations (MCOs). Depending on the state, reimbursement can differ. For example, some states may provide higher reimbursement rates for preventive services or chronic disease management.

Physicians must refer to state-specific Medicaid provider manuals for accurate billing instructions, as rules can vary significantly across states. Understanding local requirements ensures compliance and prevents payment delays or denials.

3.0 Private Payer Policies

Private insurance payers, such as UnitedHealthcare, Aetna, Cigna, and Blue Cross Blue Shield (BCBS), typically require physicians to follow strict billing guidelines as outlined in their payer contracts. These contracts often specify:

• Fee schedules for physician services

• Definitions for medical necessity that align with the insurer’s standards

• Documentation requirements to prove that the services were medically necessary

• Policies regarding prior authorization for certain procedures or services

Payers also provide medical policy bulletins that outline specific billing instructions and updates for CPT codes and ICD-10 diagnoses. For example, insurers like Aetna or UnitedHealthcare may update policies to reflect changes in medical evidence or industry standards.

Example:

• UnitedHealthcare Policy 0123: This policy details how to bill for specialist services and the necessary documentation for reimbursement approval.

It’s important to stay updated on these bulletins to prevent underpayment or claim denials.

4.0 Key Legal Considerations in Physician Medical Billing

Physicians must adhere to legal standards and compliance regulations when submitting claims for reimbursement. Key issues include:
