R45.8Other symptoms and signs involving emotional state

R45.8 is the ICD-10-CM diagnosis code for other symptoms and signs involving emotional state. It belongs to category R45 (symptoms and signs involving emotional state), block R40-R46 (symptoms and signs involving cognition, perception, emotional state and behavior) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

Within R45, choose R45.8 (Other symptoms and signs involving emotional state) only when documentation doesn't support a more specific option: Nervousness (R45.0), Restlessness and agitation (R45.1), unhappiness (R45.2), Demoralization and apathy (R45.3), irritability and anger (R45.4), Hostility (R45.5), Violent behavior (R45.6) and state of emotional shock and stress, unspecified (R45.7).

To report this condition, pick the subcode that matches the documentation: R45.81 (self-esteem), R45.82 (Worries), R45.83 (adult), R45.84 (Anhedonia), R45.85 (ideations), R45.86 (lability), R45.87 (Impulsiveness), R45.88 (self-harm) and 1 more.

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