Extracting diagnosis codes from a variable

[mosadoluwa]

Hello,

I need help extracting unique ICD 10 diagnosis codes from a character variable (ICD10_with_Description):

Have

ICD9  ICD10_with_Description

431 I61.0 Nontraumatic intracerebral hemorrhage in hemisphere, subcortical I61.1 Nontraumatic intracerebral hemorrhage in hemisphere, cortical I61.2 Nontraumatic intracerebral hemorrhage in hemisphere

431 I61.4 Nontraumatic intracerebral hemorrhage in cerebellum I61.5 Nontraumatic intracerebral hemorrhage, intraventricular

431 I61.6 Nontraumatic intracerebral hemorrhage, multiple localized I61.8 Other nontraumatic intracerebral hemorrhage

437.7 G45.4 Transient global amnesia

I want a dataset with 1 var

Unique_dx

I610

I611

I612

I614

I615

I616

I618

G454

Thank you for your help!

Do digits occur anywhere in that description other than in the codes?

I would be very leery of discarding that decimal. I don't use ICD codes much but would worry about complications such as

I6.11 and I61.1 ending up as the same value.

@ballardw Digits occur only in the codes.
