About R68.3

R68.3 is the ICD-10-CM diagnosis code for Clubbing of fingers. It belongs to category R68 (other general symptoms and signs), block R50-R69 (general symptoms and signs) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 205 (Other Respiratory System Diagnoses with MCC, relative weight 1.8244) and DRG 206 (Other Respiratory System Diagnoses without MCC, relative weight 0.9257), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 781.5 (Clubbing of fingers).
