CPT® Code 83655 is used to report laboratory testing for lead in a patient's specimen. Lead testing is commonly performed to identify lead exposure or elevated blood lead levels, particularly in children and individuals with potential occupational, environmental, or household exposure.
Lead exposure can affect multiple organ systems, making timely testing important when exposure is suspected or when screening is recommended based on age, risk factors, or applicable public health guidelines.
This code represents the laboratory lead test itself, not specimen collection or separate evaluation and management services, which may be reported separately when appropriate.
Key Facts About CPT® 83655
- Service type: Laboratory toxicology test
- Test: Lead level
- Specimen type: Typically blood
- Test purpose: Detect and measure lead exposure
- Provider type: Physicians, laboratories, and qualified healthcare professionals
Common clinical indications:
- Suspected lead exposure
- Childhood lead screening
- Occupational exposure
- Environmental exposure
- Follow-up of previously elevated blood lead levels
- Evaluation of symptoms potentially associated with lead toxicity
When to Use CPT® 83655
CPT 83655 is appropriate when:
- A provider orders lead testing to evaluate potential exposure
- Screening is indicated based on the patient's age, risk factors, or applicable recommendations
- Monitoring is needed following a previously elevated blood lead level
- Occupational or environmental exposure is suspected
Examples:
- Screening a child who lives in an older home where lead exposure may be possible
- Testing an individual with potential occupational exposure to lead
- Rechecking blood lead levels after a previous elevated result
- Evaluating a patient following a known environmental lead exposure
Documentation Requirements
To support CPT 83655 billing, documentation should include:
- Patient identifiers and date of service
- Clinical indication for lead testing
- Relevant exposure history or screening rationale
- Specimen type and collection information
- Lead test performed
- Test result and date reported
- Ordering provider information
Complete documentation helps establish medical necessity and supports accurate laboratory billing.
Reimbursement and Coding Considerations
- CPT 83655 is used to report lead testing
- Diagnosis coding should support screening, suspected exposure, elevated blood lead levels, or another medically necessary indication
- Screening recommendations and coverage requirements can vary based on age, risk factors, state requirements, and payer policy
- Follow-up testing may be medically necessary when an elevated blood lead level is identified
- Specimen collection may be billed separately when permitted by payer guidelines
Always verify payer-specific laboratory and lead screening requirements before submitting claims.
