Mapping rules for ICD10CM

1. If we have kind of group T22.042 Burn of unspecified degree of left axilla T22.042A Burn of unspecified degree of left axilla, initial encounter T22.042D Burn of unspecified degree of left axilla, subsequent encounter T22.042S Burn of unspecified degree of left axilla, sequela

T22.042 Burn of unspecified degree of left axilla T22.042A Burn of unspecified degree of left axilla, initial encounter T22.042D Burn of unspecified degree of left axilla, subsequent encounter we map to 84493007 Burn of axilla (condition described in parent node itself)

and T22.042S Burn of unspecified degree of left axilla, sequela we map to 77890001 Late effect of burn of extremities, except wrist AND hand (consequence of this condition as a distinct concept in a target vocabulary)

The same rule if we have more concepts there like

S62.299A Other fracture of first metacarpal bone, unspecified hand, initial encounter for closed fracture S62.299B Other fracture of first metacarpal bone, unspecified hand, initial encounter for open fracture S62.299D Other fracture of first metacarpal bone, unspecified hand, subsequent encounter for fracture with routine healing S62.299G Other fracture of first metacarpal bone, unspecified hand, subsequent encounter for fracture with delayed healing S62.299K Other fracture of first metacarpal bone, unspecified hand, subsequent encounter for fracture with nonunion S62.299P Other fracture of first metacarpal bone, unspecified hand, subsequent encounter for fracture with malunion S62.299S Other fracture of first metacarpal bone, unspecified hand, sequela or even S82.62 Displaced fracture of lateral malleolus of left fibula S82.62XA Displaced fracture of lateral malleolus of left fibula, initial encounter for closed fracture S82.62XB Displaced fracture of lateral malleolus of left fibula, initial encounter for open fracture type I or II S82.62XC Displaced fracture of lateral malleolus of left fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC S82.62XD Displaced fracture of lateral malleolus of left fibula, subsequent encounter for closed fracture with routine healing S82.62XE Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type I or II with routine healing S82.62XF Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing S82.62XG Displaced fracture of lateral malleolus of left fibula, subsequent encounter for closed fracture with delayed healing S82.62XH Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type I or II with delayed healing S82.62XJ Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing S82.62XK Displaced fracture of lateral malleolus of left fibula, subsequent encounter for closed fracture with nonunion S82.62XM Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type I or II with nonunion S82.62XN Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion S82.62XP Displaced fracture of lateral malleolus of left fibula, subsequent encounter for closed fracture with malunion S82.62XQ Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type I or II with malunion S82.62XR Displaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion S82.62XS Displaced fracture of lateral malleolus of left fibula, sequela S as last symbol of code means sequela
