CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

J69.1 is a billable ICD-10-CM diagnosis code for pneumonitis due to inhalation of oils and essences. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 177 through 179. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 125 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Aspiration pneumonitis and Lung disease due to external agents.

For Medicare Advantage risk adjustment, J69.1 maps to CMS-HCC Category 282 (Aspiration and Specified Bacterial Pneumonias) under the V28 model, adding a risk factor of about 0.440 for a community, non-dual, aged beneficiary in payment year 2026.

Questions About J69.1Overview

What is the ICD-10 code for pneumonitis due to inhalation of oils and essences?

The ICD-10-CM code for pneumonitis due to inhalation of oils and essences is J69.1 (sometimes written as J691). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Is J69.1 (Pneumonitis due to solids and liquids) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report pneumonitis due to inhalation of oils and essences on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does J69.1 group to?

When pneumonitis due to inhalation of oils and essences is the principal diagnosis on an inpatient stay, it groups to MS-DRG 177, 178, 179, with relative weights from 0.7550 to 1.5627 depending on complications. Higher weights mean higher Medicare reimbursement.

Is J69.1 a CC or MCC?

CMS lists J69.1 as an MCC (major complication or comorbidity) for FY 2026. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 125 closely related codes in its exclusion list.

What is the ICD-9 equivalent of J69.1?

Under the General Equivalence Mappings, pneumonitis due to inhalation of oils and essences converts to ICD-9-CM 507.1 (oil/essence pneumonitis). The mapping is a direct match.

What HCC is J69.1?

J69.1 (pneumonitis due to inhalation of oils and essences) maps to CMS-HCC Category 282 (Aspiration and Specified Bacterial Pneumonias), commonly written as HCC 282, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2026. It mapped to HCC 114 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does J69.1 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, J69.1 adds a risk adjustment factor of about 0.440 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.173 to 0.538 depending on the payment segment). HCC 282 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 282 category page.
