ICD-10 code for lumbosacral sprain

The ICD-10-CM code for lumbosacral sprain is S33.9 (Sprain of unspecified parts of lumbar spine and pelvis).

Within S33, choose S33.9 (Sprain of unspecified parts of lumbar spine and pelvis) only when documentation doesn't support a more specific option: traumatic rupture of lumbar intervertebral disc (S33.0), subluxation and dislocation of lumbar vertebra (S33.1), dislocation of sacroiliac and sacrococcygeal joint (S33.2), dislocation of other and unspecified parts of lumbar spine and pelvis (S33.3), traumatic rupture of symphysis pubis (S33.4), sprain of ligaments of lumbar spine (S33.5), sprain of sacroiliac joint (S33.6) and sprain of other parts of lumbar spine and pelvis (S33.8).

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.
