D0180 is the CDT code for a comprehensive periodontal evaluation — a detailed exam focused on the gums and supporting bone, with full pocket charting. It's used for new or returning patients who show signs of gum disease or have risk factors for it.
What D0180 means
D0180 covers a comprehensive periodontal evaluation for new or established patients. "D" is dental, "01" is the diagnostic family, and "80" is this periodontal-focused exam. Unlike a general comprehensive exam (D0150), it centers on the health of the gums and the bone that supports the teeth.
It includes detailed periodontal probing and charting — measuring the pocket depth around each tooth — along with assessment of gum recession, bleeding, tooth mobility, and the supporting bone, usually with X-rays. This builds the baseline needed to diagnose gum disease and plan treatment like scaling and root planing.
It's appropriate for patients who show signs or symptoms of periodontal disease, or who have risk factors such as smoking, diabetes, or a family history. Because it overlaps with other exams, plans typically won't pay D0180 and a comprehensive (D0150) or periodic (D0120) exam on the same day; the dentist chooses the one that fits the visit.
When it's typically used
D0180 is reported for new or returning patients with signs, symptoms, or risk factors for periodontal disease, when a detailed gum-and-bone evaluation with full pocket charting is performed to diagnose and plan treatment.
How much does D0180 cost?
A comprehensive periodontal evaluation is comparable to other thorough exams, often roughly 50 to 150 USD depending on region and office. Supporting X-rays are coded and charged separately.
Is D0180 covered by insurance?
Coverage varies; some plans reimburse D0180 under diagnostic benefits, others pay it at the standard comprehensive-exam rate or fold it into exam frequency limits. It generally can't be billed the same day as another comprehensive or periodic exam.
