Coding Guidelines for G32.0

G32.0 is a valid ICD-10-CM diagnosis code meaning 'Subacute combined degeneration of spinal cord in diseases classified elsewhere'.

It is also suitable for:

  • Dana-Putnam syndrome
  • Sclerosis of spinal cord (combined) (dorsolateral) (posterolateral)

Purely Excluded Conditions

These diag codes should never be used at the same time as G32.0 because these conditions cannot occur together:

  • syphilitic combined degeneration of spinal cord (A52.11)

Must Code Etiology Before Coding G32.0

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.

G32.0 is a manifestation code. For it to be valid, one of the following etiology codes must also be coded first:

  • underlying disease, such as:
  • other dietary vitamin B12 deficiency anemia (D51.3)
  • vitamin B12 deficiency anemia due to intrinsic factor deficiency (D51.0)
  • vitamin B12 deficiency anemia, unspecified (D51.8)
  • vitamin B12 deficiency (E53.8)

Complications & Comorbid Conditions (CC/MCC) Rules for G32.0

When G32.0 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).

Exclusions apply. When the primary diagnostic code is is in the exclusion list, the patient visit CC/MCC does not qualify for a CC or MCC.

CC/MCC grouping rules are adjusted each year, so check the rules for the fiscal year of the patient's discharge date.

DRG Mapping Rules for G32.0

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 G32.0, 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.
