In homecare, Ecodes assist in medical review where an trauma or injury occurs.

LevelI of HCPCS

InHCPCS, level I comprises of Current Procedural Terminology (CPT-4)that is a numeric system for coding used by American MedicalAssociation (AMA). Level I comprises of a uniform coding system madeup of the descriptive terms and identifies the codes that are usedspecifically in identifying medical services as well as theprocedures that are furnished by the physicians and otherprofessionals within the healthcare. Level I enhances identificationof procedures and services for billing the private or publicinsurance programs. This does not include codes that are separatelyrequired to report medical services or the items.

LevelII of HCPCS

LevelII of HCPCS refers to a standardized system used for coding, and ismajorly used in identifying the products, services and supplies thatare not included in CPT-4 codes, like durable medical equipment andambulance services, orthotics, prosthetics and supplies when usedoutside the office of the physician. The equipment and supplies arenot covered by CPT-4 codes since Medicare and some other insurers areinvolved in various services. The establishment of level II codes wasto enhance submission of claims for such items.
