2021 ICD-10-CM Codes for Chronic gout (M1A)

Instructional Notations

Use Additional Code Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

  • code to identify:
  • Autonomic neuropathy in diseases classified elsewhere G99.0
  • Calculus of urinary tract in diseases classified elsewhere N22
  • Cardiomyopathy in diseases classified elsewhere I43
  • Disorders of external ear in diseases classified elsewhere H61.1 H62.8
  • Disorders of iris and ciliary body in diseases classified elsewhere H22
  • Glomerular disorders in diseases classified elsewhere N08

Type 1 Excludes Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • acute gout M10

7th Character Note 7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category M1A

7th Character 7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.

  • 0 - without tophus (tophi)
  • 1 - with tophus (tophi)
