Valid for Submission
R03.1 is a billable diagnosis code used to specify a medical diagnosis of nonspecific low blood-pressure reading. The code R03.1 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code R03.1 might also be used to specify conditions or terms like decreased blood pressure, not hypotension, decreased diastolic arterial pressure, decreased mean arterial pressure, decreased systolic arterial pressure or low blood pressure reading.
According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code R03.1:
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code R03.1 are found in the index:
- - Abnormal, abnormality, abnormalities - See Also: Anomaly;
- - Blood
- - pressure
- - low - See Also: Hypotension;
- - pressure
- - Low
- - Pressure
- - hyposystolic - See Also: Hypotension;
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Decreased blood pressure, not hypotension
- Decreased diastolic arterial pressure
- Decreased mean arterial pressure
- Decreased systolic arterial pressure
- Low blood pressure reading

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Information for Patients
Low Blood Pressure
You've probably heard that high blood pressure is a problem. Sometimes blood pressure that is too low can also cause problems.
Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Your blood pressure reading uses these two numbers. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure.
Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of a medical condition or certain medicines. Some people may have symptoms of low blood pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.
