It is also suitable for:

  • Neurogenic bladder due to cauda equina syndrome

Complications & Comorbid Conditions (CC/MCC) Rules for G83.4

When G83.4 is used as a secondary diagnostic code, the patient's visit may be considered to have Complications & Comorbid Conditions (CC) or Major Complications & Comorbid Conditions (MCC).

DRG Mapping Rules for G83.4

Diagnostic codes are the first step in the DRG mapping process.

The patient's primary diagnostic code is the most important. Assuming the patient's primary diagnostic code is G83.4, look in the list below to see which MDC's "Assignment of Diagnosis Codes" is first. That is the MDC that the patient will be grouped into.

From there, check the subsections of the MDC listed. The patient will be mapped into the first subsection for which the treatment performed on the patient meet the listed requirements of that subsection.

DRG grouping rules are adjusted each year, so make sure to check the rules for the fiscal year of the patient's discharge date.
