Code first
The underlying condition below must be sequenced before E08. E08 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code
Report an additional code alongside E08 to fully describe the condition. E08 is sequenced first.
Excludes1 — never code together — inherited from Chapter 4
The conditions below can never be reported together with E08 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- transitory endocrine and metabolic disorders specific to newborn (P70-P74)
