This classification is used in medical billing and clinical recording to specify the clinical criteria for caisson disease decompression sickness (ICD-10-CM T70.3), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Official Registry Overview & Definition
Caisson disease decompression sickness is a non-billable ICD-10-CM category code T70.3. A more specific billable subcode must be selected for claims submission. Inclusion terms: Compressed-air disease; Diver's palsy or paralysis.
