About M48.50

M48.50 is the ICD-10-CM diagnosis code for Collapsed vertebra, not elsewhere classified, site unspecified. It belongs to category M48 (other spondylopathies), block M45-M49 (spondylopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within M48.5, choose M48.50 (site unspecified) only when documentation doesn't support a more specific option: occipito-atlanto-axial region (M48.51), cervical region (M48.52), cervicothoracic region (M48.53), thoracic region (M48.54), thoracolumbar region (M48.55), lumbar region (M48.56), lumbosacral region (M48.57) and sacral and sacrococcygeal region (M48.58).

Codes in this range require a 7th character: A for initial encounter for fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing and S for sequela of fracture. 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.

7th character

The appropriate 7th character is to be added to each code from subcategory M48.5:

  • Ainitial encounter for fractureM48.50XA
  • Dsubsequent encounter for fracture with routine healingM48.50XD
  • Gsubsequent encounter for fracture with delayed healingM48.50XG
