About coding toe s wound
The ICD-10-CM code for toe s wound is S91.109 (Unspecified open wound of unspecified toe(s) without damage to nail). The official index lists 13 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S91.109.
Within S91.10, choose S91.109 (unspecified toe(s) without damage to nail) only when documentation doesn't support a more specific option: right great toe without damage to nail (S91.101), left great toe without damage to nail (S91.102), unspecified great toe without damage to nail (S91.103), right lesser toe(s) without damage to nail (S91.104), left lesser toe(s) without damage to nail (S91.105) and unspecified lesser toe(s) without damage to nail (S91.106).
