Definitions & Coding Indicators
Preventive Care
Definition:
Preventive services are delivered in the absence of symptoms, as part of a routine wellness visit. These services aim to prevent illness or detect it before symptoms develop.
Examples:
Annual physical exams
Immunizations (flu, tetanus, etc.)
Screening mammogram
Colonoscopy (routine, age-based)
Well-woman and well-child exams
Routine lab work (e.g., cholesterol panel, glucose)
Depression or STD screening during wellness visits
Medical/Diagnostic Care
Definition:
Medical diagnostic services are provided in response to specific symptoms, complaints, or medical history. These services are used to diagnose or manage an existing condition.
Examples:
Colonoscopy due to GI bleeding or family history of colon cancer
Mammogram to investigate a lump or pain
Lab work ordered due to abnormal physical exam or symptoms
Imaging ordered due to chest pain, headache, or injury
Special Situations
1. Dual-Purpose Visits
Situation: A visit is both preventive and diagnostic (e.g., patient has routine exam and addresses a complaint like back pain).
The medical provider will split the visit into preventive and diagnostic components. The provider will bill for a preventive procedure code AND a medical office visit code.
Cost-sharing may apply to the diagnostic portion only; the copay will be applied to the medical office visit.
2. Screening Becomes Diagnostic
Situation: A screening service (e.g., a preventive colonoscopy) results in a clinical finding (e.g., polyps).
The claim is processed based on how it is billed.
If the primary diagnosis code reflects a preventive service, the claim is processed as preventive, and no cost sharing applies.
If the primary diagnosis code reflects a medical or diagnostic indication (e.g., abdominal pain, rectal bleeding, history of polyps), the claim is considered diagnostic and will be processed accordingly (standard medical benefits apply, including any applicable cost sharing).
The principal diagnosis is the condition established after study to be chiefly responsible for occasioning the patient’s admission or visit.
