ICD-10 code for febrile convulsions

The ICD-10-CM code for febrile convulsions is R56.00 (Simple febrile convulsions). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R56.00.

Within R56.0 (febrile convulsions), R56.00 is specifically for simple febrile convulsions. Related codes cover complex febrile convulsions (R56.01).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 100 (Seizures with MCC, relative weight 1.9233), DRG 101 (Seizures without MCC, relative weight 0.8952), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
