About L41

L41 is the ICD-10-CM diagnosis code for parapsoriasis. It belongs to block L40-L45 (papulosquamous disorders) and chapter 12 (diseases of the skin and subcutaneous tissue). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: L41.0 (acuta), L41.1 (chronica), L41.3 (parapsoriasis), L41.4 (parapsoriasis), L41.5 (parapsoriasis), L41.8 (parapsoriasis) and L41.9 (unspecified).

Don't report L41 together with the conditions in its Excludes1 note: poikiloderma vasculare atrophicans (L94.5).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
