Coding Guidelines for G63

G63 is a valid ICD-10-CM diagnosis code meaning 'Polyneuropathy in diseases classified elsewhere'.

Purely Excluded Conditions

These diag codes should never be used at the same time as G63 because these conditions cannot occur together:

  • polyneuropathy (in):
  • diabetes mellitus (E08-E13 with .42)
  • diphtheria (A36.83)
  • infectious mononucleosis (B27.0-B27.9 with 1)
  • Lyme disease (A69.22)
  • mumps (B26.84)
  • postherpetic (B02.23)
  • rheumatoid arthritis (M05.5-)
  • scleroderma (M34.83)
  • systemic lupus erythematosus (M32.19)
Must Code Etiology Before Coding G63

Some conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation.

G63 is a manifestation code. For it to be valid, one of the following etiology codes must also be coded first:

  • underlying disease, such as:
  • amyloidosis (E85.-)
  • endocrine disease, except diabetes (E00-E07, E15-E16, E20-E34)
  • metabolic diseases (E70-E88)
  • neoplasm (C00-D49)
  • nutritional deficiency (E40-E64)

Complications & Comorbid Conditions (CC/MCC) Rules for G63

G63 is not a CC or MCC.

DRG Mapping Rules for G63

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 G63, 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.
