7th character note

This category requires a 7th character to indicate additional clinical detail (e.g. encounter type: initial, subsequent, sequela). The code is incomplete without it.

The appropriate 7th character is to be added to each code from subcategories S89.0, S89.1, S89.2, and S89.3

Documentation support

General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.

•This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
•This code describes an unspecified presentation. If the medical record documents a more specific detail (e.g. laterality, type, or affected site), a more specific sibling code should be used instead — see Related codes below.
•This category requires a 7th character. Documentation should clearly indicate the episode of care (initial encounter, subsequent encounter, or sequela).
•As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
