ICD-10 code for adhesions
From the official ICD-10-CM alphabetic index entry “Adhesions, adhesive (postinfective)”. Page updated September 29, 2026.
About coding adhesions
The ICD-10-CM code for adhesions is K66.0 (Peritoneal adhesions (postprocedural) (postinfection)). The official index lists 110 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K66.0.
Within K66 (other disorders of peritoneum), K66.0 is specifically for peritoneal adhesions (postprocedural) (postinfection). Related codes cover Hemoperitoneum (K66.1), other specified disorders of peritoneum (K66.8) and disorder of peritoneum, unspecified (K66.9).
Don't report K66.0 together with the conditions in its Excludes1 note: peritoneal adhesions with intestinal obstruction (K56.5-).
The conditions in its Excludes2 note aren't part of K66.0, but may be coded alongside it if the patient has both: female pelvic adhesions [bands] (N73.6) and female pelvic postprocedural adhesions (N99.4).
