ICD-10 Code J98.6 – Disorders of diaphragm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J98.6 – Disorders of diaphragm
What it is
J98.6 identifies disorders affecting the diaphragm, the main muscle used for breathing. Use it for documented diaphragm abnormalities, dysfunction, or related conditions when the record does not specify a more precise code.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see dyspnea, reduced chest expansion, orthopnea, or imaging evidence of diaphragmatic elevation or weakness.
When to use this code
Use J98.6 when the provider documents a diaphragm disorder without naming a more specific diagnosis. It may fit cases such as diaphragmatic paralysis, weakness, or dysfunction when the record supports a diaphragm problem but lacks detail. Check documentation if the cause is known and coded elsewhere.
Do not use for
Do not use this code for nonspecific shortness of breath or for disorders clearly arising from another organ system. If the chart identifies a different primary condition, code that condition instead.
Coding tip
Confirm whether the note names paralysis, eventration, or another specific diaphragm diagnosis before defaulting to J98.6.
