About L97.215

L97.215 is the ICD-10-CM diagnosis code for Non-pressure chronic ulcer of right calf with muscle involvement without evidence of necrosis. It belongs to category L97 (Non-pressure chronic ulcer of lower limb, not elsewhere classified), 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 L97.21, choose L97.215 (with muscle involvement without evidence of necrosis) only when documentation doesn't support a more specific option: limited to breakdown of skin (L97.211), with fat layer exposed (L97.212), with necrosis of muscle (L97.213), with necrosis of bone (L97.214), with bone involvement without evidence of necrosis (L97.216), with other specified severity (L97.218) and with unspecified severity (L97.219).

Code first any associated underlying condition, such as: any associated gangrene (I96), atherosclerosis of the lower extremities (I70.23-, I70.24-, I70.33-, I70.34-, I70.43-, I70.44-, I70.53-, I70.54-, I70.63-, I70.64-, I70.73-, I70.74-), chronic venous hypertension (I87.31-, I87.33-), diabetic ulcers (E08.621, E08.622, E09.621, E09.622, E10.621, E10.622, E11.621, E11.622, E13.621, E13.622) and 3 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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 was added in FY2018, effective October 1, 2017.

Before ICD-10, this condition was coded in ICD-9-CM as 707.12 (ulcer of calf).
