About coding pelvis bite
The ICD-10-CM code for pelvis bite is S31.050 (Open bite of lower back and pelvis without penetration into retroperitoneum). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S31.050.
Within S31.05, choose S31.050 (without penetration into retroperitoneum) only when documentation doesn't support a more specific option: with penetration into retroperitoneum (S31.051).
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.
