About coding thumb bite
The ICD-10-CM code for thumb bite is S61.05 (Open bite of thumb without damage to nail). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S61.05.
Within S61.0, choose S61.05 (Open bite of thumb without damage to nail) only when documentation doesn't support a more specific option: unspecified open wound of thumb without damage to nail (S61.00), laceration without foreign body of thumb without damage to nail (S61.01), laceration with foreign body of thumb without damage to nail (S61.02), puncture wound without foreign body of thumb without damage to nail (S61.03) and puncture wound with foreign body of thumb without damage to nail (S61.04).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
Don't report S61.05 together with the conditions in its Excludes1 note: superficial bite of thumb (S60.36-, S60.37-).
