Excludes1 — never code together — inherited from M14
The conditions below can never be reported together with M14.842 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 — inherited from M14.8
The underlying condition below must be sequenced before M14.842. M14.842 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 13
