About coding Encopresis
The ICD-10-CM code for Encopresis is R15.9 (Full incontinence of feces). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R15.9.
Within R15 (fecal incontinence), R15.9 is specifically for full incontinence of feces. Related codes cover incomplete defecation (R15.0), fecal smearing (R15.1) and fecal urgency (R15.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
