Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to R41.3: its own notes plus those printed at R41, block R40-R46, and Chapter 18. A note printed at a category, block or chapter applies to every code under it.

Applicable To

Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.

  • Amnesia NOS
  • Memory loss NOS

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On R41.3 itself
  • amnestic disorder due to known physiologic condition (F04)
  • amnestic syndrome due to psychoactive substance use (F10-F19 with 5th character .6)
  • mild memory disturbance due to known physiological condition (F06.8)
  • transient global amnesia (G45.4)
From R41 Other symptoms and signs involving cognitive functions and awareness applies to 16 codes
  • dissociative [conversion] disorders (F44.-)
  • mild cognitive impairment of uncertain or unknown etiology (G31.84)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block R40-R46 Symptoms and signs involving cognition, perception, emotional state and behavior applies to 157 codes
  • symptoms and signs constituting part of a pattern of mental disorder (F01-F99)
From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • certain conditions originating in the perinatal period (P04-P96)
  • signs and symptoms classified in the body system chapters
  • signs and symptoms of breast (N63, N64.5)

Notes

General instructions on how these codes are used.

From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill-defined conditions regarding which no diagnosis classifiable elsewhere is recorded.
  • Signs and symptoms that point rather definitely to a given diagnosis have been assigned to a category in other chapters of the classification. In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'. The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. The residual subcategories, numbered .8, are generally provided for other relevant symptoms that cannot be allocated elsewhere in the classification.
  • The conditions and signs or symptoms included in categories R00-R94 consist of:
  • (a) cases for which no more specific diagnosis can be made even after all the facts bearing on the case have been investigated;
  • (b) signs or symptoms existing at the time of initial encounter that proved to be transient and whose causes could not be determined;
  • (c) provisional diagnosis in a patient who failed to return for further investigation or care;
  • (d) cases referred elsewhere for investigation or treatment before the diagnosis was made;
  • (e) cases in which a more precise diagnosis was not available for any other reason;
  • (f) certain symptoms, for which supplementary information is provided, that represent important problems in medical care in their own right.

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)

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

What is the ICD-10 code for other amnesia?

The ICD-10-CM code for other amnesia is R41.3 (sometimes written as R413). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

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, 2026 through September 30, 2027.

What MS-DRG does R41.3 group to?

When other amnesia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 948, 947, with relative weights from 0.7833 to 1.2608 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.

Can R41.3 be reported with F04?

Not as a rule. The Excludes1 note on R41.3 lists "amnestic disorder due to known physiologic condition (F04)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
