How this service works
Search ICD-10-CM diagnosis codes by words in the description, with the matching codes and their chapters.
Output
Returns a list of matching ICD-10-CM diagnosis codes, each with the code string, official description, and chapter number. Also includes total match count, the number shown, query echo, data source, and an optional summary. Result count is configurable from 1 to 25 (default 10).
Example use cases
Medical billing code lookup for clinicians
“I need to find the right ICD-10-CM codes for a patient with congestive heart failure — can you search for 'heart failure' and show me the top 10 results with their chapter numbers?”
EHR auto-coding workflow
“For our EHR system, search ICD-10-CM for 'major depressive disorder' and give me up to 20 matching diagnosis codes with descriptions so I can pre-populate the dropdown.”
Medical research code set assembly
“Can you find all ICD-10-CM diagnosis codes related to 'chronic obstructive pulmonary disease' and list their codes, descriptions, and chapters — give me up to 25 results?”
Technical details
Endpoint
GEThttps://medical-codes.x402tookit.com/icd10-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search ICD-10-CM codes by natural language description keywords rather than looking up a specific known code. Ideal for billing automation, EHR pre-population, clinical documentation assistance, or any workflow where a diagnosis term needs to be mapped to one or more ICD-10-CM codes. Prefer this over exact-code lookup endpoints when the user knows the condition name but not the specific code.
Side effects
- No matching codes found for an ambiguous or misspelled query
- Query too vague returns unrelated codes
- Limit parameter outside 1-25 range may cause validation error
- Degraded mode may return partial results with a degraded flag set to true
- Missing required 'q' parameter returns an error
