How is D16.4 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to D16.4. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Cyst › calcifying odontogenic › upper jaw (colloid) (mucous) (simple) (retention)

Excludes2 — not included here

The conditions below are not part of D16.4, but a patient may have both at the same time. When documentation supports it, D16.4 and the excluded code may both be reported.

  • benign neoplasm of lower jaw bone (D16.5)

Inclusion terms

Alternative wording in documentation that is classified to D16.4.

  • Benign neoplasm of maxilla (superior)
  • Benign neoplasm of orbital bone
  • Keratocyst of maxilla
  • Keratocystic odontogenic tumor of maxilla

Excludes1 — never code together — inherited from D16

The conditions below can never be reported together with D16.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • benign neoplasm of connective tissue of ear (D21.0)
  • benign neoplasm of connective tissue of eyelid (D21.0)
  • benign neoplasm of connective tissue of larynx (D14.1)
  • benign neoplasm of connective tissue of nose (D14.0)
  • benign neoplasm of synovia (D21.-)

How long has D16.4 existed?
