J47.0 is a billable ICD-10-CM diagnosis code for bronchiectasis with acute lower respiratory infection. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 190 through 192. 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 21 closely related codes. Coders also document this condition as acute bronchitis co-occurrent with bronchiectasis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Chronic obstructive pulmonary disease and bronchiectasis.
For Medicare Advantage risk adjustment, J47.0 maps to CMS-HCC Category 280 (Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders) under the V28 model, adding a risk factor of about 0.319 for a community, non-dual, aged beneficiary in payment year 2027.

Notes
General instructions on how these codes are used.
- When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).

Bronchial Disorders
When you breathe in, the air travels down through your trachea (windpipe). It then goes through two tubes to your lungs. These tubes are your bronchi. Bronchial disorders can make it hard for you to breathe.

Questions About J47.0Overview
What is the ICD-10 code for bronchiectasis with acute lower respiratory infection?
The ICD-10-CM code for bronchiectasis with acute lower respiratory infection is J47.0 (sometimes written as J470). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is J47.0 (Bronchiectasis) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report bronchiectasis with acute lower respiratory infection on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does J47.0 group to?
When bronchiectasis with acute lower respiratory infection is the principal diagnosis on an inpatient stay, it groups to MS-DRG 192, 190, 191, with relative weights from 0.6285 to 1.0749 depending on complications. Higher weights mean higher Medicare reimbursement.
Is J47.0 a CC or MCC?
CMS lists J47.0 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 21 closely related codes in its exclusion list.
Can J47.0 be reported with Q33.4?
Not as a rule. The Excludes1 note at J47, which applies to J47.0, lists "congenital bronchiectasis (Q33.4)". 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).
What HCC is J47.0?
J47.0 (bronchiectasis with acute lower respiratory infection) maps to CMS-HCC Category 280 (Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders), commonly written as HCC 280, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 112 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 229.
Does J47.0 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, J47.0 adds a risk adjustment factor of about 0.319 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.209 to 0.390 depending on the payment segment). A more severe related category (HCC 276, HCC 277, HCC 278, and HCC 279) supersedes it when both are reported. See the full factor table on the HCC 280 category page.
