R41 is a non-billable ICD-10-CM category code for other symptoms and signs involving cognitive functions and awareness, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R41.0, R41.1, R41.2, and R41.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Instructional NotesGuidance

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

Excludes1

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

  • 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.

Questions About R41Overview

What is the ICD-10 code for other symptoms and signs involving cognitive functions and awareness?

R41 is the ICD-10-CM category for other symptoms and signs involving cognitive functions and awareness, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is R41 a billable code?

No. This is a category header that groups the codes for other symptoms and signs involving cognitive functions and awareness, and headers cannot be submitted on claims. Claims for other symptoms and signs involving cognitive functions and awareness need a more specific code from this category, such as R41.0, R41.1, and R41.2.

Can R41 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the other symptoms and signs involving cognitive functions and awareness is established, that condition takes the principal position instead.

Can R41 be reported with a code from F44?

Not as a rule. The Excludes1 note on R41 lists "dissociative [conversion] disorders (F44.-)". 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).
