About coding Fecalith
The ICD-10-CM code for Fecalith is K56.41 (Fecal impaction). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K56.41.
Within K56.4 (other impaction of intestine), K56.41 is specifically for fecal impaction. Related codes cover other impaction of intestine (K56.49).
The conditions in its Excludes2 note aren't part of K56.41, but may be coded alongside it if the patient has both: incomplete defecation (R15.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
