Z15.0

Genetic susceptibility to malignant neoplasm

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z15.0 is a billable code used to indicate a diagnosis of genetic susceptibility to malignant neoplasm.

Key Diagnostic Point:

Z15.0 indicates a genetic predisposition to malignant neoplasms, which can significantly influence patient health status and their interactions with healthcare services. Individuals with a known genetic susceptibility, such as BRCA mutations, may require enhanced screening protocols, preventive measures, and tailored aftercare strategies. Social determinants of health, including access to genetic counseling, socioeconomic status, and education, play a crucial role in how these patients manage their health. Preventive care may involve regular screenings, lifestyle modifications, and discussions about risk-reducing surgeries. Screening protocols should be adjusted based on family history and genetic findings, while aftercare may include ongoing monitoring and psychological support. Proper documentation of genetic testing results and patient education is essential for accurate coding and reimbursement.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for comprehensive family history documentation
  • Variability in genetic testing results interpretation
  • Integration of social determinants of health in care planning
  • Potential for multiple related diagnoses

Audit Risk Factors

  • Inadequate documentation of genetic testing results
  • Failure to link Z15.0 with appropriate screening codes
  • Misinterpretation of family history relevance
  • Lack of evidence for preventive measures taken

Specialty Focus

Medical Specialties

Primary Care

Documentation Requirements

Document family history, genetic testing results, and preventive care plans.

Common Clinical Scenarios

Routine checkups for patients with known genetic risks, discussions about preventive measures, and referrals for genetic counseling.

Billing Considerations

Consider social determinants such as access to care, education level, and patient understanding of genetic risks.

Public Health

Documentation Requirements

Collect population-level data on genetic predispositions and their impact on health outcomes.

Common Clinical Scenarios

Epidemiological studies assessing the prevalence of genetic mutations in specific populations and their correlation with cancer rates.

Billing Considerations

Focus on health equity and access to genetic testing and counseling services.

Coding Guidelines

Inclusion Criteria

Use Z15.0 When
  • Z codes are used to indicate factors influencing health status and should be sequenced appropriately
  • 0 should be used when genetic susceptibility is a significant factor in the patient's care plan
  • Payer requirements may vary, so it's essential to verify coverage for genetic testing and related preventive services

Exclusion Criteria

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding genetic susceptibilities, enabling better tracking of patient populations at risk for malignancies and improving preventive care strategies.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding genetic susceptibilities, enabling better tracking of patient populations at risk for malignancies and improving preventive care strategies.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding genetic susceptibilities, enabling better tracking of patient populations at risk for malignancies and improving preventive care strategies.
