MDC 01 Diseases & Disorders of the Nervous System is broken down into subgroups, listed here from most to least resource intensive. If a patient received qualifying treatment in listed in more than one subgroup, the first one listed will determine the DRG assigned to the patient.
To determine if a patient qualifies for a subgroup, click on the subgroup name and check the requirements listed. Typically, each subgroup requires one of a serious of ICD-10-CM diagnostic codes or PCS codes to have been assigned to the patient.
To qualify for any subsection in this MDC, the patient's primary diagnostic code must be included in this list.
