S52.136Nondisplaced fracture of neck of unspecified radius

S52.136 is the ICD-10-CM diagnosis code for nondisplaced fracture of neck of unspecified radius. It belongs to category S52 (fracture of forearm), block S50-S59 (injuries to the elbow and forearm) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 16 subcodes must be used instead.

Within S52.13, choose S52.136 (Nondisplaced fracture of neck of unspecified radius) only when documentation doesn't support a more specific option: displaced fracture of neck of right radius (S52.131), displaced fracture of neck of left radius (S52.132), displaced fracture of neck of unspecified radius (S52.133), nondisplaced fracture of neck of right radius (S52.134) and nondisplaced fracture of neck of left radius (S52.135).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture type I or II, C for initial encounter for open fracture type IIIA, IIIB, or IIIC, D for subsequent encounter for closed fracture with routine healing, E for subsequent encounter for open fracture type I or II with routine healing, F for subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing and 10 more. 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.
