ICD-10 Code I00: Rheumatic fever without heart involvement
ICD-10 Code I00: definition, billable status, and 2026 validity Most claim denials for acute rheumatic fever trace back to a single documentation error: the coder chose I00 when the patient’s record showed early-stage carditis. ICD-10 Code I00 is a billable, specific ICD-10-CM diagnosis code representing rheumatic fever without heart involvement. That distinction drives every coding […]
ICD-10 Code H67.3: Otitis media in diseases classified elsewhere, bilateral
ICD-10 Code H67.3 reports otitis media in diseases classified elsewhere, bilateral – middle ear inflammation in both ears that develops as a manifestation of an underlying systemic disease rather than as a primary ear condition. It sits in the H67 category, which requires the underlying disease to be sequenced first and depends on the chart […]
ICD-10 Code H54.7: Unspecified visual loss
ICD-10 Code H54.7: Definition and clinical description ICD-10 Code H54.7 is a billable diagnosis code for unspecified visual loss, used when the medical record does not document laterality or WHO-graded visual acuity. Most other vision-related diagnoses in ICD-10-CM require the coder to specify which eye is affected and how severely; H54.7 exists for the cases […]
ICD-10 Code H82.2: Vertiginous syndromes, left ear
ICD-10 Code H82.2 identifies vertiginous syndromes in diseases classified elsewhere, left ear. It’s a manifestation code, so it’s only ever assigned alongside the underlying disease code — typically Meniere’s disease or labyrinthitis — that’s producing the vertigo. Missing either code triggers claim denials, which is why accurate medical coding depends on capturing both together. This […]
ICD-10 Code N28.0: Ischemia and infarction of kidney
ICD-10 Code N28.0 is the official ICD-10-CM diagnosis code for ischemia and infarction of kidney. It is a billable/specific code, meaning it meets the required level of specificity for HIPAA-covered transaction submission. The code sits within chapter 14 (Diseases of the genitourinary system), block N25-N29 (Other disorders of kidney and ureter), under category N28 (Other […]
ICD-10 Code E67.1: Hypercarotenemia diagnosis and coding guide
E67.1 is the billable ICD-10 code for hypercarotenemia, high blood carotene that yellows skin but spares the sclera, unlike jaundice.
ICD-10 Code H92.13: Otorrhea, bilateral
ICD-10 Code H92.13 is the billable, laterality-specific code for otorrhea, bilateral: ear discharge affecting both ears at once. It applies whenever a clinician’s note confirms both ears are involved, replacing the unspecified default, H92.10, that many practices default to out of habit. This reference covers the code’s clinical definition, billable status, the full H92 sibling […]
ICD-10 Code H10.9: Unspecified conjunctivitis
ICD-10 Code H10.9 is the billable code for conjunctivitis when documentation does not specify the type, cause, or affected eye. It’s the correct choice most of the time, but a meaningful share of H10.9 claims have documentation that supports a more specific code the coder did not dig for. This reference covers the official code […]
ICD-10 Code D43.2: Neoplasm of uncertain behavior of brain, unspecified
ICD-10 Code D43.2: Definition and billable status ICD-10 Code D43.2 is a billable ICD-10-CM code for neoplasm of uncertain behavior of brain, unspecified. It applies when a pathology report or imaging note documents that a brain mass cannot be classified as malignant, benign, or in-situ, and the record does not specify whether the location is […]
ICD-10 Code H50.30: Unspecified intermittent heterotropia
ICD-10 Code H50.30 is a billable, specific ICD-10-CM diagnosis code for unspecified intermittent heterotropia. Coders assign it when the clinical record does not specify whether the deviation is esotropia or exotropia, or which eye is affected. This reference covers the code hierarchy, sibling codes, includes and excludes notes, CPT pairings for strabismus surgery and vision […]
