About L89.142

L89.142 is the ICD-10-CM diagnosis code for pressure ulcer of left lower back, stage 2. It belongs to category L89 (pressure ulcer), block L80-L99 (other disorders of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within L89.14 (pressure ulcer of left lower back), L89.142 is specifically for pressure ulcer of left lower back, stage 2. Related codes cover unstageable (L89.140), stage 1 (L89.141), stage 3 (L89.143), stage 4 (L89.144), Pressure-induced deep tissue damage of left lower back (L89.146) and unspecified stage (L89.149).

Code first: any associated gangrene (I96).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 573 (Skin Graft for Skin Ulcer or Cellulitis with MCC, relative weight 6.3575), DRG 574 (Skin Graft for Skin Ulcer or Cellulitis with CC, relative weight 3.5674), DRG 575 (Skin Graft for Skin Ulcer or Cellulitis without CC/MCC, relative weight 1.8797), DRG 592 (Skin Ulcers with MCC, relative weight 1.9101), DRG 593 (Skin Ulcers with CC, relative weight 1.1575) and DRG 594 (Skin Ulcers without CC/MCC, relative weight 0.7801), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 707.03 (pressure ulcer, lower back) and 707.22 (pressure ulcer, stage II).
