Is J16 billable?
No — J16 is a non-billable header code. J16 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 2 billable codes beneath J16.

Excludes1 — never code together
The conditions below can never be reported together with J16 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before J16. J16 describes a manifestation and cannot be the principal or first-listed diagnosis.
Code also
Two codes may be needed to describe the condition fully. Whether J16 is sequenced first depends on the reason for the encounter.
