Questions About R19.2Overview
Is R19.2 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report visible peristalsis on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does R19.2 group to?
When visible peristalsis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 391, 392, with relative weights from 0.7796 to 1.2683 depending on complications. Higher weights mean higher Medicare reimbursement.
Can R19.2 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the visible peristalsis is established, that condition takes the principal position instead.
What is the ICD-9 equivalent of R19.2?
Under the General Equivalence Mappings, visible peristalsis converts to ICD-9-CM 787.4 (visible peristalsis). 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.
