• •This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
• •Confirm the excluded condition(s) listed above are not also present — Excludes1 conditions cannot be coded together with this one.
• •This category requires a 7th character. Documentation should clearly indicate the episode of care (initial encounter, subsequent encounter, or sequela).
