About coding Pseudocyesis
The ICD-10-CM code for Pseudocyesis is F45.8 (Other somatoform disorders).
Within F45, choose F45.8 (Other somatoform disorders) only when documentation doesn't support a more specific option: Somatization disorder (F45.0), Undifferentiated somatoform disorder (F45.1), hypochondriacal disorders (F45.2), pain disorders related to psychological factors (F45.4) and somatoform disorder, unspecified (F45.9).
Don't report F45.8 together with the conditions in its Excludes1 note: sleep related teeth grinding (G47.63).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for F45.8)
- sleep related teeth grinding (G47.63)
