ICD-10-CM R09
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

R09 is a non-billable ICD-10-CM category code for other symptoms and signs involving the circulatory and respiratory system, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R09.01, R09.02, R09.1, and R09.2. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Specific Coding for Oth symptoms and signs involving the circ and resp sysOverview

Non-specific codes like R09 require more characters. Use one of these billable codes instead:

  • R09.0 for Asphyxia and hypoxemia

  • Use R09.01 for Asphyxia

  • Use R09.02 for Hypoxemia

  • Use R09.1 for Pleurisy

  • Use R09.2 for Respiratory arrest

  • Use R09.3 for Abnormal sputum

  • R09.8 for Other specified symptoms and signs involving the circulatory and respiratory systems

  • Use R09.81 for Nasal congestion

  • Use R09.82 for Postnasal drip

  • Use R09.89 for Other specified symptoms and signs involving the circulatory and respiratory systems

  • R09.A for Foreign body sensation of the circulatory and respiratory system

  • Use R09.A0 for Foreign body sensation, unspecified

  • Use R09.A1 for Foreign body sensation, nose

  • Use R09.A2 for Foreign body sensation, throat

  • Use R09.A9 for Foreign body sensation, other site

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to R09: its own notes plus those printed at 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.

  • acute respiratory distress syndrome (J80)
  • respiratory arrest of newborn (P28.81)
  • respiratory distress syndrome of newborn (P22.0)
  • respiratory failure (J96.-)
  • respiratory failure of newborn (P28.5)

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 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)
  • signs and symptoms classified in the body system chapters
  • signs and symptoms of breast (N63, N64.5)

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.

Breathing Problems

When you're short of breath, it's hard or uncomfortable for you to take in the oxygen your body needs. You may feel as if you're not getting enough air. Sometimes you can have mild breathing problems because of a stuffy nose or intense exercise. But shortness of breath can also be a sign of a serious disease.

Questions About R09Overview

Is R09 a billable code?

No. This is a category header that groups the codes for other symptoms and signs involving the circulatory and respiratory system, and headers cannot be submitted on claims. Claims for other symptoms and signs involving the circulatory and respiratory system need a more specific code from this category, such as R09.01, R09.02, and R09.1.

Can R09 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the other symptoms and signs involving the circulatory and respiratory system is established, that condition takes the principal position instead.

Can R09 be reported with J80?

Not as a rule. The Excludes1 note on R09 lists "acute respiratory distress syndrome (J80)". 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).
