About coding Clubnail
The ICD-10-CM code for Clubnail is R68.3 (Clubbing of fingers). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R68.3.
Within R68 (other general symptoms and signs), R68.3 is specifically for Clubbing of fingers. Related codes cover hypothermia, not associated with low environmental temperature (R68.0), nonspecific symptoms peculiar to infancy (R68.1), dry mouth, unspecified (R68.2) and other general symptoms and signs (R68.8).
Don't report R68.3 together with the conditions in its Excludes1 note: congenital clubfinger (Q68.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
