Questions About L92.9Overview

Is L92.9 (Granulomatous disorders of skin and subcutaneous tissue) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report granulomatous disorder of the skin and subcutaneous tissue, unspecified on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does L92.9 group to?

When granulomatous disorder of the skin and subcutaneous tissue, unspecified 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.

What is the ICD-9 equivalent of L92.9?

Under the General Equivalence Mappings, granulomatous disorder of the skin and subcutaneous tissue, unspecified converts to ICD-9-CM 701.5 (abnormal granulation 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.
