R41.3 is a billable ICD-10-CM diagnosis code for other amnesia. 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 Nervous system signs and symptoms.

Clinical InformationClinical

  • Amnesia

    pathologic partial or complete loss of the ability to recall past experiences (amnesia, retrograde) or to form new memories (amnesia, anterograde). this condition may be of organic or psychologic origin. organic forms of amnesia are usually associated with dysfunction of the diencephalon or hippocampus. (from adams et al., principles of neurology, 6th ed, pp426-7)

  • Amnesia, Anterograde

    loss of the ability to form new memories beyond a certain point in time. this condition may be organic or psychogenic in origin. organically induced anterograde amnesia may follow craniocerebral trauma; seizures; anoxia; and other conditions which adversely affect neural structures associated with memory formation (e.g., the hippocampus; fornix (brain); mammillary bodies; and anterior thalamic nuclei). (from memory 1997 jan-mar;5(1-2):49-71)

  • Amnesia, Retrograde

    loss of the ability to recall information that had been previously encoded in memory prior to a specified or approximate point in time. this process may be organic or psychogenic in origin. organic forms may be associated with craniocerebral trauma; cerebrovascular accidents; seizures; dementia; and a wide variety of other conditions that impair cerebral function. (from adams et al., principles of neurology, 6th ed, pp426-9)

  • Amnesia, Transient Global

    a syndrome characterized by a transient loss of the ability to form new memories. it primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours. during the period of amnesia, immediate and recent memory abilities are impaired, but the level of consciousness and ability to perform other intellectual tasks are preserved. the condition is related to bilateral dysfunction of the medial portions of each temporal lobe. complete recovery normally occurs, and recurrences are unusual. (from adams et al., principles of neurology, 6th ed, pp429-30)

  • Temporal Lobe

    lower lateral part of the cerebral hemisphere responsible for auditory, olfactory, and semantic processing. it is located inferior to the lateral fissure and anterior to the occipital lobe.

Patient EducationClinical

Memory

Every day, you have different experiences and you learn new things. Your brain cannot store all of that information, so it has to decide what is worth remembering. Memory is the process of storing and then remembering this information. There are different types of memory. Short-term memory stores information for a few seconds or minutes.

Questions About R41.3Overview

Is R41.3 a billable code?

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

What MS-DRG does R41.3 group to?

When other amnesia 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 R41.3 be a principal diagnosis?

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

What is the ICD-9 equivalent of R41.3?

Under the General Equivalence Mappings, other amnesia converts to ICD-9-CM 780.93 (memory loss). 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.
