About coding toe s bite
The ICD-10-CM code for toe s bite is S91.15 (Open bite of toe without damage to nail). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S91.15.
Within S91.1, choose S91.15 (Open bite of toe without damage to nail) only when documentation doesn't support a more specific option: unspecified open wound of toe without damage to nail (S91.10), laceration without foreign body of toe without damage to nail (S91.11), laceration with foreign body of toe without damage to nail (S91.12), puncture wound without foreign body of toe without damage to nail (S91.13) and puncture wound with foreign body of toe without damage to nail (S91.14).
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 S91.15 together with the conditions in its Excludes1 note: superficial bite of toe (S90.46-, S90.47-).
