How is S63.64 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to S63.64. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Sprain › thumb › metacarpophalangeal (joint) (ligament)

Excludes1 — never code together — inherited from S63.6

The conditions below can never be reported together with S63.64 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • traumatic rupture of ligament of finger at metacarpophalangeal and interphalangeal joint(s) (S63.4-)

Use additional code — inherited from Chapter 19

Report an additional code alongside S63.64 to fully describe the condition. S63.64 is sequenced first.
