Ulcerative colitis, unspecified with other complication

This code signifies ulcerative colitis where the specific type (e.g., pancolitis, proctitis) is not documented, and the patient is experiencing a complication other than hemorrhage, fistula, or abscess. These "other complications" could include strictures, toxic megacolon, or extraintestinal manifestations.

Assign this code when documentation confirms a diagnosis of ulcerative colitis, but the anatomical extent is not specified, and a complication is present that does not have a more specific ICD-10-CM code. This code is appropriate when the physician explicitly states "ulcerative colitis with other complication" or describes a complication not otherwise classified.

• Always attempt to clarify the anatomical extent of the ulcerative colitis and the specific type of complication for more precise coding.
• Do not use this code if the complication is hemorrhage (K51.x11), fistula (K51.x12), or abscess (K51.x13); use the appropriate specific code.
• Sequence this code as the primary diagnosis if the ulcerative colitis with complication is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity affecting care.
