2027 ICD-10-CM Diagnosis Code R06.3Periodic breathing
ICD-10-CM Codes›R00–R99›R00-R09›R06
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
R06.3 is a billable ICD-10-CM diagnosis code for periodic breathing. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 204. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 24 closely related codes. 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 breathing pattern disorder. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory signs and symptoms and Sleep wake disorders.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to R06.3: its own notes plus those printed at R06 and Chapter 18. A note printed at a category, block or chapter applies to every code under it.
Applicable To
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.
- Cheyne-Stokes breathing
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
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.
Notes
General instructions on how these codes are used.
- 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 R06.3Overview
What is the ICD-10 code for periodic breathing?
The ICD-10-CM code for periodic breathing is R06.3 (sometimes written as R063). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is R06.3 (Abnormalities of breathing) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report periodic breathing on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does R06.3 group to?
When periodic breathing is the principal diagnosis on an inpatient stay, it groups to MS-DRG 204 (respiratory Signs and Symptoms), which carries a relative weight of 0.8208. Higher weights mean higher Medicare reimbursement.
Is R06.3 a CC or MCC?
CMS lists R06.3 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 24 closely related codes in its exclusion list.
Can R06.3 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the periodic breathing is established, that condition takes the principal position instead.
