Introduction

Modifier 32 is used to indicate that a service was mandated by a third party, such as a government agency, court, employer, workers’ compensation program, or other organization with legal authority. Unlike routine medical care that is initiated by the patient or physician, services reported with Modifier 32 are performed because an external entity requires the examination, evaluation, or treatment.

Although Modifier 32 is not used frequently in everyday medical billing, it is important for billers, coders, and AR callers to understand its purpose. Correct use helps identify services that were legally or administratively required and may affect claim processing, reimbursement, or documentation requirements.

Plain English Explanation

Modifier 32 tells the payer:

“This medical service was performed because it was required by a third party, not solely because the patient or physician requested it.”

The provider still performs a medically appropriate service, but the reason for the visit is a legal, regulatory, or administrative requirement.

Purpose of Modifier 32

Modifier 32 is used to:

Identify services required by law or regulation.
Distinguish mandated services from routine patient-requested care.
Inform the payer that the examination or evaluation was required by a third party.
Support correct claim processing according to payer policies.

When to Use Modifier 32

Modifier 32 may be appropriate when a medical service is required by:

A court order.
A government agency.
Workers’ compensation authority.
State or federal regulations.
An employer, when permitted by payer policy.
An insurance carrier requiring an independent medical evaluation.
Child protective services or other authorized agencies.

Common Examples

Example 1 – Court-Ordered Medical Examination

A court orders a physician to evaluate an individual after a legal proceeding.

The physician performs:

Complete medical history.
Physical examination.
Written medical report.

Modifier 32 may be appropriate if payer policy allows.

Example 2 – Workers’ Compensation Evaluation

An employee sustains a workplace injury.

The employer’s workers’ compensation carrier requires an independent medical examination.

The provider performs the examination and documents findings.

Modifier 32 may be reported when appropriate under payer guidelines.

Example 3 – Government Agency Examination

A state agency requests a physician evaluation to determine medical eligibility for a public program.

The physician performs the requested examination and completes the required documentation.

When NOT to Use Modifier 32

Do not use Modifier 32 when:

The patient voluntarily schedules the visit.
The physician independently recommends the service.
Routine preventive care is performed.
An insurance company merely requests additional records.
The service is medically necessary but not legally mandated.
Another modifier more accurately describes the service.

Medicare Rules

Modifier 32 is recognized within the CPT coding system, but its use under Medicare is relatively uncommon.

Important considerations include:

Medicare reimbursement depends on coverage rules, medical necessity, and claim requirements.
Modifier 32 does not automatically establish Medicare coverage.
Supporting documentation may be requested.
Certain mandated examinations may not be covered by Medicare if they do not meet Medicare benefit requirements.

Always review current CMS manuals and Medicare Administrative Contractor (MAC) guidance before billing.

Commercial Insurance Rules

Commercial insurance policies vary.

Some payers may:

Accept Modifier 32.
Require documentation proving the service was mandated.
Process the claim differently depending on the responsible payer.
Require prior authorization or supporting legal documentation.

Always verify payer-specific requirements before claim submission.

Documentation Requirements

Documentation should include:

The reason the service was mandated.
Name of the requesting agency, court, employer, or organization.
Medical necessity of the evaluation performed.
Complete examination findings.
Assessment and recommendations.
Any required reports or legal documentation.

The documentation should clearly demonstrate who required the service and why.

Real Billing Examples

Example 1 – Independent Medical Examination

An insurance carrier requests an independent medical evaluation following a workplace injury.

The physician performs:

Comprehensive history.
Physical examination.
Functional assessment.
Written report.

Coding Example

Appropriate E/M code with Modifier 32 (if payer policy permits).

Example 2 – Court-Ordered Physical Examination

A judge orders a physical examination during a legal case.

The physician performs the required evaluation and submits findings to the court.

Modifier 32 may be appropriate when the payer recognizes its use.

Example 3 – Incorrect Use

A patient voluntarily schedules an annual physical examination.

Modifier 32 should not be reported because the visit was not legally or administratively mandated.
