Questions About R23.8Overview

Is R23.8 (Other skin changes) a billable code?

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

What MS-DRG does R23.8 group to?

When other skin changes is the principal diagnosis on an inpatient stay, it groups to MS-DRG 606, 607, with relative weights from 0.9064 to 1.5132 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R23.8 be a principal diagnosis?

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

What is the ICD-9 equivalent of R23.8?

Under the General Equivalence Mappings, other skin changes converts to ICD-9-CM 782.9 (integument tiss symp NEC). The mapping is approximate, so confirm the match fits the documentation.

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.
