Common ICD-10-CM Codes for Clinical Concepts for OB/GYN ICD-10-CM

Clinical Concepts for OB/GYN providers see a recurring set of conditions, and this reference collects the 363 ICD-10-CM codes they report most often, organized into 11 clinical concepts from abnormal female genital cytology onward. Billable codes carry the green check; entries with the amber note point at a category where a more specific code should be considered first. Every code links to its full code page for verification.
