About coding feigning illness person
The ICD-10-CM code for feigning illness person is Z76.5 (Malingerer [conscious simulation]).
Within Z76 (persons encountering health services in other circumstances), Z76.5 is specifically for Malingerer [conscious simulation]. Related codes cover encounter for issue of repeat prescription (Z76.0), encounter for health supervision and care of foundling (Z76.1), encounter for health supervision and care of other healthy infant and child (Z76.2), healthy person accompanying sick person (Z76.3), other boarder to healthcare facility (Z76.4) and persons encountering health services in other specified circumstances (Z76.8).
Don't report Z76.5 together with the conditions in its Excludes1 note: factitious disorder (F68.1-, F68.A) and peregrinating patient (F68.1-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
