About coding nose bite
The ICD-10-CM code for nose bite is S01.25 (Open bite of nose). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S01.25.
Within S01.2 (open wound of nose), S01.25 is specifically for open bite of nose. Related codes cover unspecified open wound of nose (S01.20), laceration without foreign body of nose (S01.21), laceration with foreign body of nose (S01.22), puncture wound without foreign body of nose (S01.23) and puncture wound with foreign body of nose (S01.24).
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 S01.25 together with the conditions in its Excludes1 note: superficial bite of nose (S00.36, S00.37).
