CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

R93.41 is a billable ICD-10-CM diagnosis code for abnormal radiologic findings on diagnostic imaging of renal pelvis, ureter, or bladder. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 695 through 696. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. Coders also document this condition as cystoscopy abnormal. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Abnormal findings without diagnosis.

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.

  • Filling defect of bladder found on diagnostic imaging
  • Filling defect of renal pelvis found on diagnostic imaging

Excludes1

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

From Block R90-R94 Abnormal findings on diagnostic imaging and in function studies, without diagnosis applies to 64 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • diagnostic abnormal findings classified elsewhere - see Alphabetical Index

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 R93.4 Abnormal findings on diagnostic imaging of urinary organs applies to 5 codes
  • hypertrophy of kidney (N28.81)
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)

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 R93.41Overview

Is R93.41 (Abnormal findings on diagnostic imaging of urinary organs) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report abnormal radiologic findings on diagnostic imaging of renal pelvis, ureter, or bladder on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does R93.41 group to?

When abnormal radiologic findings on diagnostic imaging of renal pelvis, ureter, or bladder is the principal diagnosis on an inpatient stay, it groups to MS-DRG 696, 695, with relative weights from 0.6677 to 1.1136 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R93.41 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal radiologic findings on diagnostic imaging of renal pelvis, ureter, or bladder is established, that condition takes the principal position instead.

Can R93.41 be reported with a code from O28?

Not as a rule. The Excludes1 note at block R90-R94, which applies to R93.41, lists "abnormal findings on antenatal screening of mother (O28.-)". 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).

What is the ICD-9 equivalent of R93.41?

Under the General Equivalence Mappings, abnormal radiologic findings on diagnostic imaging of renal pelvis, ureter, or bladder converts to ICD-9-CM 793.5 (nonsp abn find-gu organs). The mapping is approximate, so confirm the match fits the documentation.
