Bruises

A bruise is a mark on your skin caused by blood trapped under the surface. It happens when an injury crushes small blood vessels but does not break the skin. Those vessels break open and leak blood under the skin.

Questions About R23.3Overview

Is R23.3 (Other skin changes) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report spontaneous ecchymoses on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can R23.3 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the spontaneous ecchymoses is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R23.3?

Under the General Equivalence Mappings, spontaneous ecchymoses converts to ICD-9-CM 782.7 (spontaneous ecchymoses). The mapping is a direct match.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
