ICD-10 Code J98.19 – Other pulmonary collapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J98.19 – Other pulmonary collapse
What it is
J98.19 identifies collapse of lung tissue that is not otherwise specified as classic atelectasis. Use it when the record describes a pulmonary collapse diagnosis without a more exact code.
Clinical signs
Clinical features vary; refer to documentation. Commonly, notes may describe reduced air entry, decreased breath sounds, or imaging showing partial lung collapse.
When to use this code
Use J98.19 when the provider documents “other pulmonary collapse” or a similar non-specific collapse diagnosis. It is appropriate when the chart does not support a more detailed atelectasis or related pulmonary code. Check documentation if the cause or anatomic site is unclear.
Do not use for
Do not use this code for routine postoperative atelectasis or when a more specific diagnosis is documented. If the record names a different lung disorder, code that condition instead.
Coding tip
Confirm the exact wording in the assessment and imaging report before assigning J98.19.
