ICD-10-CM R97.20
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R97.20 is a billable ICD-10-CM diagnosis code for elevated prostate specific antigen [PSA]. 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. The code is restricted by the Medicare Code Editor to adult patients (age 15 through 124) and flagged as a questionable admission, since it rarely justifies inpatient admission on its own. 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 prostate specific antigen above reference range. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Abnormal findings without diagnosis.

Code EditsBilling

Medicare Code Editor checks that affect claim validity for R97.20.

Adult diagnoses
The Medicare Code Editor detects inconsistencies in adult cases by checking a patient's age and any diagnosis on the patient's record. The adult code edits apply to patients age range is 15–124 years inclusive (e.g., senile delirium, mature cataract).
Questionable admission codes
Some diagnoses are not usually sufficient justification for admission to an acute care hospital. For example, if a patient is given code R030 for elevated blood pressure reading, without diagnosis of hypertension, then the patient would have a questionable admission, since elevated blood pressure reading is not normally sufficient justification for admission to a hospital. The following list contains diagnosis codes identified as questionable admission when used.

Prostate Cancer Screening

Cancer is a disease when the cells of the body grow out of control. Cancer screening is having tests to look for signs of cancer before you have any symptoms. By the time cancer causes symptoms, it may have already spread to other parts of your body. A screening test may help find cancer early, when it may be easier to treat.
