ICD-10 code K63.1: Perforation of intestine (nontraumatic)
ICD-10 code K63.1 is the billable diagnosis code for perforation of the intestine (nontraumatic): a full-thickness breach of the bowel wall caused by disease rather than an external injury. It covers spontaneous and disease-related perforations from diverticulitis, Crohn’s disease, malignancy, and ischemic bowel, and it excludes perforations caused by trauma. This reference covers K63.1’s billable […]
ICD-10 code M43.4: Other recurrent atlantoaxial dislocation
ICD-10 code M43.4 reports other recurrent atlantoaxial dislocation: repeated displacement of the C1-C2 joint without myelopathy. Coders assign it when the clinical record supports a recurring pattern, backed by imaging and documented episode history, rather than a single traumatic event. This ICD-10-CM code sits within category M43, alongside a small family of related dorsopathy codes. […]
ICD-10 code M16.7: Other unilateral secondary osteoarthritis of hip
A claim for hip osteoarthritis gets denied for one of two reasons more often than any other: the secondary cause never made it into the note, or nobody recorded which hip is affected. ICD-10 code M16.7 covers unilateral secondary hip OA, and it only holds up when both of those details are on the record. […]
ICD-10 code S82.155P: left tibial tuberosity fracture guide
ICD-10 code S82.155P identifies a nondisplaced fracture of the left tibial tuberosity – the bony prominence just below the knee where the patellar tendon attaches – at a subsequent encounter where the fracture has healed with malunion. This guide breaks down the code’s structure, correct clinical use, and the billing codes practices commonly pair with […]
ICD-10 Code S92.301K: Metatarsal fracture with nonunion
ICD-10 Code S92.301K identifies a fracture of unspecified metatarsal bone(s) of the right foot at a subsequent encounter where the bone has failed to unite. It’s the code coders reach for once imaging confirms nonunion rather than routine or delayed healing. This page covers the full 7th-character set for S92.3 fractures, the coding hierarchy, related […]
ICD-10 Code S82.232M: Left tibial shaft fracture with nonunion
ICD-10 Code S82.232M is a billable code for a displaced oblique fracture of the shaft of the left tibia, subsequent encounter for an open fracture type I or II with nonunion. It applies once the fracture has stopped healing rather than simply healing slowly, which changes both the encounter type and the code itself. Getting […]
ICD-10 Code N96: Recurrent pregnancy loss
N96 is the ICD-10-CM code for recurrent pregnancy loss (RPL): a history of two or more pregnancy losses before 22 weeks gestation in a patient who is not currently pregnant. It’s also one of the more documentation-sensitive codes in the ICD-10-CM genitourinary chapter. Coders and reproductive medicine clinicians frequently hit claim denials not because the […]
ICD-10 Code M15.8: Other polyosteoarthritis
Claims for multi-joint osteoarthritis get denied more often than coders expect, usually for the same reason: the wrong M15 code went on the claim. ICD-10 code M15.8, other polyosteoarthritis, is the code for exactly that situation, osteoarthritis across several joints that the provider has documented as a specific type, yet one that doesn’t fit a […]
ICD-10 Code M16.6: Other bilateral secondary osteoarthritis of hip
ICD-10 code M16.6 is the billable diagnosis code for other bilateral secondary osteoarthritis of hip, valid for FY2026. It applies when both hip joints show osteoarthritis and physician documentation names a cause that isn’t dysplasia or a prior injury. The catch is documentation. Most M16.6 denials come down to one missing detail: the note confirms […]
ICD-10 Code I15.1: Hypertension secondary to other renal disorders
ICD-10 Code I15.1 is the billable diagnosis code for hypertension secondary to other renal disorders: high blood pressure caused by a kidney condition other than a renovascular mechanism, such as chronic kidney disease, glomerulonephritis, or polycystic kidney disease. Coders often default to I10 (essential hypertension) even when the record documents a renal cause, which is […]
