Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Polyneuropathies and other disorders of the peripheral nervous system
      (G60-G65)
      • Sequelae of inflammatory and toxic polyneuropathies
        (G65)

G65 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of sequelae of inflammatory and toxic polyneuropathies. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

G65 is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like e of inflammatory and toxic polyneuropathies. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Specific Coding Applicable to Sequelae of inflammatory and toxic polyneuropathies

Non-specific codes like G65 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for sequelae of inflammatory and toxic polyneuropathies:

  • Use G65.0 for Sequelae of Guillain-Barre syndrome - BILLABLE CODE

  • Use G65.1 for Sequelae of other inflammatory polyneuropathy - BILLABLE CODE

  • Use G65.2 for Sequelae of toxic polyneuropathy - BILLABLE CODE

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
