ICD-10-CM R93.6
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R93.6 is a billable ICD-10-CM diagnosis code for abnormal findings on diagnostic imaging of limbs. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 564 through 566. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Abnormal findings without diagnosis.

Questions About R93.6Overview

Is R93.6 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report abnormal findings on diagnostic imaging of limbs on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does R93.6 group to?

When abnormal findings on diagnostic imaging of limbs is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 565, 566, with relative weights from 0.7493 to 1.5436 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R93.6 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal findings on diagnostic imaging of limbs is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R93.6?

Under the General Equivalence Mappings, abnormal findings on diagnostic imaging of limbs converts to ICD-9-CM 793.7 (nonsp abn find-ms system). 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.
