- Billable — Valid for Submission
- Risk Adjusts — HCC 280
- Chronic Condition
J44.89 is a billable ICD-10-CM diagnosis code for other specified chronic obstructive pulmonary disease. 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. Coders also document this condition as chronic bronchiolitis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Chronic obstructive pulmonary disease and bronchiectasis.
For Medicare Advantage risk adjustment, J44.89 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.

A second code may be needed to fully describe the condition; the note gives no sequencing direction.
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).

Questions About J44.89Overview
What is the ICD-10 code for other specified chronic obstructive pulmonary disease?
The ICD-10-CM code for other specified chronic obstructive pulmonary disease is J44.89 (sometimes written as J4489). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is J44.89 (Other specified chronic obstructive pulmonary disease) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified chronic obstructive pulmonary disease on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does J44.89 group to?
When other specified chronic obstructive pulmonary disease 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.
Can J44.89 be reported with J68.0?
Not as a rule. The Excludes1 note at block J40-J4B, which applies to J44.89, lists "bronchitis due to chemicals, gases, fumes and vapors (J68.0)". 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 J44.89?
J44.89 (other specified chronic obstructive pulmonary disease) 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 111 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 J44.89 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, J44.89 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.
