Non-prs chronic ulcer of unsp upper arm with oth severity

This code signifies a persistent, non-pressure-related open sore located on an unspecified area of the upper arm. The ulcer's depth or tissue involvement is not specified beyond "other specified severity," indicating it's not a simple superficial erosion but also not fully categorized by a specific stage.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the upper arm, and the severity is described in a way that doesn't fit a specific stage (e.g., "partial thickness," "full thickness," but without further detail like muscle or bone involvement), or is otherwise specified without a direct stage assignment. This code is appropriate when the exact location on the upper arm (e.g., anterior, posterior) is not documented.

• Ensure the documentation explicitly states "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Avoid this code if a specific stage (e.g., stage 2, stage 3) is documented; instead, use the appropriate staged ulcer code.
• If the exact location on the upper arm is specified (e.g., right upper arm, left upper arm), a more specific code within the L98.A1- series should be sought.
