From the official ICD-10-CM alphabetic index entry “Ulcer, ulcerated, ulcerating, ulceration, ulcerative › lower limb (atrophic) (chronic) (neurogenic) (perforating) (pyogenic) (trophic) (tropical)”. Page updated September 29, 2026.

About coding lower limb ulcer

The ICD-10-CM code for lower limb ulcer is L97.909 (Non-pressure chronic ulcer of unspecified part of unspecified lower leg with unspecified severity). The official index lists 242 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L97.909.

Within L97.90, choose L97.909 (with unspecified severity) only when documentation doesn't support a more specific option: limited to breakdown of skin (L97.901), with fat layer exposed (L97.902), with necrosis of muscle (L97.903), with necrosis of bone (L97.904), with muscle involvement without evidence of necrosis (L97.905), with bone involvement without evidence of necrosis (L97.906) and with other specified severity (L97.908).

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.
