About coding vulva wound
The ICD-10-CM code for vulva wound is S31.40 (Unspecified open wound of vagina and vulva). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on S31.40.
Within S31.4, choose S31.40 (Unspecified open wound of vagina and vulva) only when documentation doesn't support a more specific option: laceration without foreign body of vagina and vulva (S31.41), laceration with foreign body of vagina and vulva (S31.42), puncture wound without foreign body of vagina and vulva (S31.43), puncture wound with foreign body of vagina and vulva (S31.44) and open bite of vagina and vulva (S31.45).
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
