CPT Code 99395: Age Group for Wellness Examination
CPT code 99395 is used for comprehensive preventive medicine wellness examinations for established patients aged 18-39 years.
Understanding the CPT Preventive Medicine Code Series
The CPT preventive medicine codes follow a structured age-based system for established patients (codes 99391-99397). Based on the evidence provided, code 99395 specifically falls within the adult preventive care series 1.
Age-Based CPT Code Structure for Preventive Care
The preventive medicine codes for established patients are organized as follows:
- 99391-99394: Pediatric and adolescent age groups (under 18 years)
- 99395: Young adults aged 18-39 years
- 99396-99397: Older adult age groups (40+ years)
The evidence consistently references the range 99381-99394 for EPSDT (Early and Periodic Screening, Diagnostic and Treatment program), which covers pediatric populations 1. Code 99395 falls immediately after this pediatric series, indicating it represents the first adult age bracket.
Clinical Context
This code is used for:
- Annual wellness examinations for established patients in the young adult age range
- Comprehensive preventive services including health risk assessment, counseling, and anticipatory guidance
- Disease detection and prevention activities appropriate for this age group 2
Important Coding Considerations
- This code applies only to established patients (those with a prior relationship with the practice)
- For new patients in the same age group, a different code series (99381-99387) would apply
- The examination should include age-appropriate preventive counseling and risk screening 2
- When acute problems are identified during the preventive visit, the -25 modifier may be used to bill for same-day problem-focused care 2
The 18-39 year age range represents a critical period for establishing healthy lifestyle patterns and screening for early risk factors that impact long-term morbidity and mortality.
