ICD-10-CM Code R03.1

Nonspecific low blood-pressure reading

Version 2020 Billable Code No Valid Principal Dx

Valid for Submission

R03.1 is a billable code used to specify a medical diagnosis of nonspecific low blood-pressure reading. The code is valid for the year 2020 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, low blood pressure reading, o/e - blood pressure decreased, etc

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.

Short Description:Nonspecific low blood-pressure reading

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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code R03.1:

Type 1 Excludes

Type 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.
  • hypotension I95
  • maternal hypotension syndrome O26.5
  • neurogenic orthostatic hypotension G90.3

Index to Diseases and Injuries

  • O/E - BP reading very low

Diagnostic Related Groups

The ICD-10 code R03.1 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2019 through 09/30/2020.

  • 314 - OTHER CIRCULATORY SYSTEM DIAGNOSES WITH MCC
  • 315 - OTHER CIRCULATORY SYSTEM DIAGNOSES WITH CC
  • 316 - OTHER CIRCULATORY SYSTEM DIAGNOSES WITHOUT CC/MCC

Convert R03.1 to ICD-9

  • 796.3 - Low blood press reading

Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00–R99)
    • Symptoms and signs involving the circulatory and respiratory systems (R00-R09)

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.
