ICD-10-CM R93.89
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R93.89 is a billable ICD-10-CM diagnosis code for abnormal findings on diagnostic imaging of other specified body structures. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 947 through 948. 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.

Clinical InformationClinical

  • Chorionic Plate Vessel Thrombus with or without Dystrophic Calcification

    a focus of thrombus adhered to the wall of a fetal blood vessel in the chorionic plate. it can be completely or partially obstructive and may lead to downstream villous injury and calcification.

  • Dystrophic Calcification

    calcium deposits in degenerated or necrotic tissue without abnormalities in blood calcium.

  • Fetal Stem Vessel Thrombus with or without Dystrophic Calcification

    a focus of thrombus adhered to the wall of a fetal stem vessel. it can be completely or partially obstructive and may lead to downstream villous injury and calcification.

  • Mediastinal Shift

    displacement of structures in the thoracic cavity in one direction due to increased pleural pressure on the contralateral side.

Questions About R93.89Overview

Is R93.89 a billable code?

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

What MS-DRG does R93.89 group to?

When abnormal findings on diagnostic imaging of other specified body structures is the principal diagnosis on an inpatient stay, it groups to MS-DRG 947, 948, with relative weights from 0.8005 to 1.2694 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R93.89 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 other specified body structures is established, that condition takes the principal position instead.

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.
