Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to R41.843: its own notes plus those printed at R41.84, R41, 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.
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.
Code First
The underlying condition named in the note is sequenced before this code.
Notes
General instructions on how these codes are used.
- 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 R41.843Overview
What is the ICD-10 code for psychomotor deficit?
The ICD-10-CM code for psychomotor deficit is R41.843 (sometimes written as R41843). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is R41.843 (Other specified cognitive deficit) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report psychomotor deficit on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does R41.843 group to?
When psychomotor deficit is the principal diagnosis on an inpatient stay, it groups to MS-DRG 884 (organic Disturbances and Intellectual Disability), which carries a relative weight of 1.5998. Higher weights mean higher Medicare reimbursement.
Can R41.843 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the psychomotor deficit is established, that condition takes the principal position instead.
Can R41.843 be reported with a code from I69.01?
Not as a rule. The Excludes1 note at R41.84, which applies to R41.843, lists "cognitive deficits as sequelae of cerebrovascular disease (I69.01-, I69.11-, I69.21-, I69.31-, I69.81-, I69.91-)". 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).
