About coding penis wound
The ICD-10-CM code for penis wound is S31.20 (Unspecified open wound of penis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on S31.20.
Within S31.2, choose S31.20 (Unspecified open wound of penis) only when documentation doesn't support a more specific option: laceration without foreign body of penis (S31.21), laceration with foreign body of penis (S31.22), puncture wound without foreign body of penis (S31.23), puncture wound with foreign body of penis (S31.24) and open bite of penis (S31.25).
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.
