What This Code Means

A chronic open sore on the buttock with a severity level that does not fit into the other specified categories of tissue damage.

Coding Tips

•Use this code only when the ulcer severity does not clearly match L98.411-L98.416 categories
•Document the specific characteristics of the ulcer in detail to justify use of this 'other specified' code

Clinical Significance

This code captures non-pressure chronic ulcers of the buttock with severity characteristics that do not fit standard depth-based categories. This may include unusual wound characteristics such as tunneling, undermining, or mixed-depth presentations. Proper documentation and coding ensure appropriate risk adjustment and reflect the true complexity of wound management.

Documentation Requirements

✓Provider documentation of the ulcer as chronic (present for extended duration, not acute)
✓Anatomical location clearly specified as buttock
✓Confirmation that the ulcer is non-pressure in etiology (e.g., venous, arterial, inflammatory, or other documented cause)
✓Description of wound bed characteristics and tissue involvement depth
✓Detailed description of the specific severity characteristics that differentiate this from standard categories
✓Wound measurements (length, width, depth) and assessment of wound edges and surrounding tissue
✓Current treatment plan including wound care interventions

Commonly Confused Codes

L89.3xx — Pressure ulcer of buttock; use when ulcer is caused by sustained pressure, not for non-pressure etiologies L98.42x — Non-pressure chronic ulcer of back; differs by anatomical location (back vs. buttock)L98.49x — Non-pressure chronic ulcer of other sites; use only when location does not match buttock, back, or specified sites L97.x — Non-pressure chronic ulcer of lower leg; different anatomical site entirely
