Coding Guidelines for G70.1

G70.1 is a valid ICD-10-CM diagnosis code meaning 'Toxic myoneural disorders'.

Must Code Etiology Before Coding G70.1

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.

G70.1 is a manifestation code. For it to be valid, one of the following etiology codes must also be coded first:

  • (T51-T65) to identify toxic agent

Complications & Comorbid Conditions (CC/MCC) Rules for G70.1

G70.1 is not a CC or MCC.

DRG Mapping Rules for G70.1

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 G70.1, 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.
